A review on the adsorption of volatile organic compounds by biomass-based porous carbon (BPC) and its mechanism
Volatile organic compounds (VOCs) are commonly produced in the combustion of fossil fuels and in chemical industries such as detergents and paints. VOCs in atmosphere cause different degrees of harm to human bodies and environments. Adsorption has become one of the most concerned methods to remove VOCs in atmosphere due to its high efficiency, simple operation and low energy consumption. Biomass-based porous carbon (BPC) has been considered as the most promising adsorption material because of the low cost and high absorption rate. In this paper, the key characteristic (e.g., specific surface area, pore structure, surface functional groups and basic composition) of BPC affecting the adsorption of VOCs in atmosphere were analyzed. The improvement of adsorption capacity of BPC by common modification methods, such as surface oxidation, surface reduction, surface loading and other modification methods, were discussed. Examples of BPC adsorption on different types of VOCs including aldehydes, ketones, aromatic VOCs, and halogenated hydrocarbons, were also reviewed. The specific adsorption mechanism was discussed. Finally, some unsolved problems and future research directions about BPC for adsorbing VOCs were propounded. This review can serve as a valuable reference for future developing effective biomass-based porous carbon VOCs adsorption technology.
期刊介绍：
Carbon Letters aims to be a comprehensive journal with complete coverage of carbon materials and carbon-rich molecules. These materials range from, but are not limited to, diamond and graphite through chars, semicokes, mesophase substances, carbon fibers, carbon nanotubes, graphenes, carbon blacks, activated carbons, pyrolytic carbons, glass-like carbons, etc. Papers on the secondary production of new carbon and composite materials from the above mentioned various carbons are within the scope of the journal. Papers on organic substances, including coals, will be considered only if the research has close relation to the resulting carbon materials. Carbon Letters also seeks to keep abreast of new developments in their specialist fields and to unite in finding alternative energy solutions to current issues such as the greenhouse effect and the depletion of the ozone layer. The renewable energy basics, energy storage and conversion, solar energy, wind energy, water energy, nuclear energy, biomass energy, hydrogen production technology, and other clean energy technologies are also within the scope of the journal. Carbon Letters invites original reports of fundamental research in all branches of the theory and practice of carbon science and technology.
