N-doped porous carbon materials were produced from palm male flower using hydrothermal carbonization processes at 200 C for 24 h followed by N-Doping and carbonization at 700C for 2 h. N-doping was carried out by impregnation using NH4OH at 0.5, 1.0, 1.5 M and 2 M. Products were characterized by means of chemical composition and morphology using SEM, XPS, and XRD to characterize specific properties such as physical morpholog, porosity, elemental composition on surface and crystalline structure of PMF. After applying hydrothermal carbonization processes, the results showed substantially increased porosity and surface area with suitable microstructure for N-doped electrodes applications. The highest porosity was obtained at NPC-1.5 M.

The utilization of biomass has recently gained great attention in recent years owing to growth of global environmental concerns. The aim of this work is to study the morphology of carbon materials derived from biomass oil palm empty fruit bunch (EFB) via hydrothermal carbonization (HTC) at different temperatures (160-200 °C) and times (4-12 h) followed by carbonization at 300-900 °C under nitrogen atmosphere for 2 h. The physiochemical properties of carbon sample were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and surface area analysis. The results demonstrated that the increase of hydrothermal temperature, hydrothermal time, and carbonization temperature resulted in the formation of carbon materials with higher surface area, porosity and carbon content. Our results revealed that carbon derived from EFB via HTC at optimal condition exhibited porous structure with high surface area, which can be further applied for absorbent applications.

In this article we address the process perspective of anodization for fabrication of nickel coating materials. In this work, we also report the mechanical properties and morphology of coating materials with various parameters. We investigated the effect of temperature and plating time with 0.3 (A/cm3) of current density. Light microscopes, Scanning Electron Microscopy and Hardness tester were used to confirm morphology and hardness of target object, respectively. In general it was observed that anodization process also affected on properties of target object. The hardness of target object with anodization process will be increased in first period and slightly decreased with high temperature and longer plating time. The chemical etching treatment had an impact on the morphological features of the AAO templates lead to morphological features of nickel coating materials. © (2013) Trans Tech Publications, Switzerland.

Carbon nanoparticles (CNPs) were successfully synthesized from the mixture of used motor oil and benzene via a solution plasma process (SPP). The synthesis was achieved within a single step at room temperature and atmospheric pressure. The effects of mixing ratio between used motor oil and benzene on the physical and chemical properties of CNPs were investigated by means of field-emission scanning electron microscopy (FESEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Raman spectroscopy. The results revealed that there were no significant changes in morphological feature and chemical functional groups on CNPs at different mixing ratios. The CNPs exhibited the aggregates of fine particles with the diameter of about 20-30 nm. The crystallinity of CNPs was found to be slightly increased when synthesized under the presence of used motor oil, possibly due to the effect of aliphatic hydrocarbons and polycyclic aromatic hydrocarbons in used motor oil. We expect that the conversion of used motor oil into CNPs by SPP could be another attractive way to add the value to used motor oil prior to disposing.

Disposal and recycle of waste biomass is of great concern. Thermochemically converting the waste biomass to carbon nanomaterials is an interesting because of environmental friendly, low cost and local availability. In this work, magnetic carbon nanofibers have been synthesized by hydrothermal and carbonization of the magnetite preloaded on horse manure which is controllable temperature and additive of catalyst. It was found that Fe is able to form magnetic carbon nanofibers (M-CNFs). Furthermore, magnetic carbon nanofibers were used as an adsorbent for methylene blue adsorption. Synthesized magnetic sorbents exhibited high performance on methylene blue adsorption and it is successfully separated from the water by magnetic separation.

Pb (II) is one of the toxic heavy metal ions, which is released from the industry, especially the manufacture of batteries and electronics-devices. Its release into the water effluents causes environmental problems and affects the humans’ and animals’ health. Adsorption is one of the conventional techniques for removal of Pb (II) in water treatment processes. The adsorbents with effective adsorption properties with their easy operation are then desired. In this study, hierarchically porous carbon monoliths with magnetic properties have been designed and successfully fabricated by incorporating sodium alginate and black liquor in ferric chloride solution. The resulting monoliths have been used to study their adsorption efficiency towards Pb (II) in aqueous solution. The interconnected macroporous structures of the materials were generated by the freeze-drying process, while the increase in microporosity was observed after pyrolysis at 700 °C (SA-BL-Fe-700). SA-BL-Fe-700 showed a magnetization of 8.79 emu/g, and high porosity, with a BET specific surface area of 945.45 m2/g and pore size distribution calculated by DFT was less than 2 nm, which is suitable to adsorb Pb (II) ions. Furthermore, the materials obtained showed a monolith feature in a cylindrical shape with strong mechanical stability, which renders them with the easy operation. The adsorption properties of SA-BL-Fe-700 monolith toward Pb (II) ions demonstrated a maximum adsorption capacity of 75.19 mg/g at pH 5 with retaining the magnetic properties. The study of adsorption behaviours illustrated that equilibrium data and kinetic study fitted with Langmuir isotherm model and pseudo-second-order model, respectively.

The livestock manure was suddenly concerned due to the crucial reason of greenhouse gases emission. Therefore, several technologies were applied to manage these waste materials such as fertilizer production, biogas or carbon material production. In this study, horse manure, a novel fibrous feedstock, was supplied to produce a carbon nanofiber for metal catalyst supporter and dye adsorbent. Carbon nanofiber was performed via hydrothermal carbonization at 200oC for 24 hours followed by carbonization at the temperature range of 300 to 900oC under the nitrogen atmosphere for 2 hours. Basically, the production yield, chemical compounds, surface morphology and pore size of produced carbon nanofiber were investigated. Dye adsorption capacity was increased by increase of carbonization temperature.

Generally, the increase in pharmaceutical industrial activities has led to a corresponding rise in water resource contamination. Efforts have been dedicated to addressing the urgent challenge of waste biomass disposal by developing recycling methods capable of producing bio-adsorbents. Adsorption is a promising approach for removing tetracycline contaminants, owing to its simplicity, stability, and cost-effectiveness. In this study, a low-cost activated biochar was successfully developed using oil palm leaf (OPL) via hydrothermal carbonization (HTC) combined microwave-assisted pyrolysis system (MAPS) using sodium hydroxide (NaOH). The HTC and MAPS processes enhanced high mass yield, porosity, energy efficiency, and reduced reaction time. NaOH treatment improved the porosity of the activated biochar derived from OPL, resulting primarily in a mesoporous structure. However, NaOH treatment via the MAPS process increased surface area and porosity. Among the samples tested, OPLC-NaOH-1:1 exhibited the largest surface area and highest porosity, making it the chosen candidate for further TC adsorption tests. The adsorption experiments revealed that the Langmuir isotherm model and the pseudo-second-order kinetic model accurately matched the experimental data, suggesting a mono-layered adsorption mechanism due to micropores and chemisorption interactions. Additionally, thermodynamic analysis indicated an endothermic and spontaneous reaction during the adsorption process. The adsorption of nanoporous carbon for TC was primarily regulated by pore filling, hydrogen bonding, electrostatic effects, and π-π interactions also playing a significant role. Overall, this study highlights the potential of utilizing OPL waste as a sustainable material for producing nanoporous carbon and underscores the effectiveness of nanoporous carbon for adsorbing antibiotics.
