Summary: Porous carbon materials with nanoscale zero-valent iron (nZVI) have higher removal efficiency for water pollutants due to nZVI reactivity. However, nZVI can sometimes affect the adsorptive properties of the carbon materials by blocking the pores and masking adsorption sites. In this study, iron-containing metal-organic framework MIL-100(Fe) was used as a precursor to prepare porous carbon rods with and without surface nZVI. The results showed that the carbon rods without nZVI had better adsorption performance for 2,4,6-trinitrotoluene under ambient conditions.

Summary: Degradability is a crucial factor in the selection of materials for biomedical applications and environmental protection. Researchers have addressed the limitation of porous carbon in these areas by designing a mesoporous carbon (MC) using biomass as a carbon source. The MC retains oxygen-containing species, thereby increasing drug adsorption capacity and degradability. The work demonstrates the potential of degradable porous materials for practical applications in biomedicine and the environment.

Summary: The use of activated orange peel as a precursor for HLPC-PO4 material synthesis resulted in a highly efficient adsorbent for the removal of U(VI) in radioactive wastewater. The material showed strong adsorption capacity and selectivity for U(VI), with a high retention of adsorption capacity even after multiple cycles. The adsorption mechanism was explained as the formation of complexes between U(VI) and P-O and P-O on the surface of the adsorbent.

Summary: This study focuses on the production of porous carbon from shaddock peel for environmental treatments. The porous carbon structure and properties were found to be influenced by carbonization conditions and the use of ZnCl2 as a pore-forming agent. By carefully adjusting the carbonization temperature and the mass ratio between ZnCl2 and shaddock peel, the resulting adsorbent showed high adsorption capacity towards methylene blue. This biomass activated carbon adsorbent has potential to be effective and environmentally friendly for water pollution treatment.

Summary: Volatile organic compounds (VOCs) are harmful to the environment and human health, and their emissions have increased with industrialization and economic growth. Adsorption is an effective technology for VOCs recovery due to its cost-effectiveness and low energy consumption. Porous carbons, such as carbon-based materials, zeolite-based materials, and organic polymers, have been extensively developed for VOCs adsorption. This paper provides an overview of the synthesis of porous carbons from renewable resources and their application in VOCs abatement technologies.

Summary: With global warming and climate change being a reality, international investments are increasingly being made in climate change mitigation. Carbon capture and separation (CCS) is gaining paramount importance as an effective solution for global warming. Sorption on porous materials, especially natural products-derived porous carbons, shows promise as an alternative to traditional CO2 capture technologies due to their sustainable availability, economic viability, and recyclability. This review provides crucial insights and analyses on the application of porous carbons in CO2 capture, including synthesis methods, structural characterization, and the use of simulation techniques. The review also outlines future research directions to progress the use of natural products-derived porous carbons for CO2 capture.

Summary: Biomass-derived nitrogen-doped hierarchical porous carbons (NHPCs) were synthesized using a one-step pyrolysis activation combined with nitrogen doping method. NHPCs possess a hierarchical porous structure with micro-meso-macropores distribution, nitrogen doping, large specific surface area, and pore volume. The NHPC-CC showed the best activation result due to the lower ash content and higher total cellulose composition content of the biomass. NHPCs demonstrated promising VOC adsorption capacity and great adsorption kinetics, attributed to the large surface area of micro-mesopores and the mass transfer channels provided by meso-macropores, respectively. The VOC with lower saturated vapor pressure exhibited higher adsorption capacity and desorption caused by substitution reaction in competitive adsorption process. NHPC-CC also showed excellent recyclability with less than 10% reduction in VOC adsorption capacity after four cycles. Overall, NHPC-CC could be a potential adsorbent for VOCs in industrial processes.

Summary: In the past decade, the removal of pharmaceuticals from aquatic bodies has received significant attention. Ibuprofen (IBP), a commonly used anti-inflammatory drug, is released into the environment through pharmaceutical waste and wastewater. Adsorption technology using carbonaceous materials has been found to be highly effective in reducing IBP in low concentrations. This comprehensive review examines the use of various carbonaceous adsorbents for IBP removal, including activated carbon, biochar, graphene-based materials, and carbon nanostructures. The studies compiled in this review indicate that some carbon-based adsorbents have higher IBP uptake than commercial activated carbons. More attention is needed for practical application and scaling up of these research findings to support water resource management and sustainability.

Summary: Selenomethionine and selenocysteine are common forms of organic selenium that are often found in industrial wastewater. This study examined the removal of these compounds using granular activated carbon (GAC) and nano zerovalent iron (nZVI) as adsorbents, with GAC demonstrating higher affinity for SeMet and SeCys removal. The kinetics data followed the pseudo-second order model, and the competitive interaction between the two compounds had an inhibitory effect on adsorption.

Summary: The effects of soluble organic biochar compounds on plant growth are not well understood. The extracted biochar solutions had different effects on the germination of corn and rice seeds, with rice straw and cotton straw solutions promoting corn germination, while cotton straw solution negatively affected it. The biochar extract solutions generally caused reduction in rice seed germination. Organic compounds present in the solutions likely promoted seed growth at lower concentrations. Determining the presence of organic moieties in biochar can help design biochars for enhanced seed germination, growth, and crop productivity.
