Summary: In this study, the effects of carbon-based adsorbents on the removal of gaseous As2O3 emitted from the coal-fired power plant were investigated. It was found that BC showed the best removal ability, with the highest effectiveness at 150 degrees Celsius. Increasing the adsorption temperature facilitated the oxidation of As3+ and chemisorption mainly occurred through oxygen-containing functional groups and As2O3. The arsenic removal ability of the carbon-based adsorbents increased initially and then decreased with increasing adsorption temperature, and the change was mainly attributed to physical adsorption.

Summary: Highly selective CO2 capture from flue gas, which faces challenges of high temperature, low partial pressure, and competition from water, is still a great challenge. Porous coordination polymers (PCPs) have been considered as a promising solution, but the rational design and function-led preparation of the pore system that permits highly selective CO2 capture remains a major obstacle. A highly selective CO2 capture from wet-hot flue gas has been achieved using a robust trap-and-flow crystal (NTU-67), which shows good stability and has the potential for practical applications.

Summary: An Al2O3/CaSiO3 adsorbent was prepared and it exhibited strong arsenic capture capacity and resistance to acidic gases. The atomic molar ratio of Al/Si at 1:5 showed the highest arsenic capture amount of 871.2 mg/kg. The doping of Al atoms altered the structure and charge distribution of CaSiO3, resulting in the formation of Al active sites with higher adsorption energy, which is more favorable for the adsorption of arsenic.

Summary: To improve heat transfer efficiency in CO2 adsorption, a rapid adsorption-desorption approach is proposed by coating a metal tube with a hydrophobic carbon layer. The coating layer made of carboxylated cellulose nanofibers, coconut shell-activated carbon, and methyltrimethoxysilane as the hydrophobic modifier. The adsorption capacity of the coated activated carbon is significantly higher than the original activated carbon, and it retains over 97% of its capacity after 10 reuses. This hydrophobic carbon coating approach is of great industrial application in CO2 capture and gas separation.

Summary: Six different porous carbons were prepared from cotton-stalk crop residue collected from various locations in India. The properties of these carbons were influenced by the collection sites, leading to variations in their microstructures and CO2 uptake performances. These carbons exhibited moderate to good CO2/N-2 separation selectivity at low temperature and could be reused for CO2 capture.

Summary: Copper-based catalysts play important roles in the hydrogenation of CO2 to methanol, and the adsorption and activation of CO2 are also crucial. In this study, a novel Cu/LTH catalyst was developed with copper nanoclusters supported on layered triple hydroxide (LTH) sphere CO2 adsorbent to simultaneously improve the microstructures and CO2 adsorption capabilities. The results showed significant improvements in the performance of Cu/LTH catalysts compared to conventional catalysts, and the LTH could enhance CO2 adsorption capability. Therefore, incorporating adsorbent into the catalyst for enhanced CO2 adsorption process is feasible and efficient.

Summary: Iron-nitrogen moieties encapsulated in N-doped graphitic and hierarchical biochars were derived from hydrothermal pyrolysis and microwave NH3 activation of cellulose and lignin, with cellulose-derived biochars showing superior activities in oxygen reduction reaction (ORR) compared to lignin-derived biochars. Among them, the C-1% biochar exhibited the best electrocatalytic performance and followed a near four-electron ORR route, attributed to the active iron-nitrogen sites covered with hierarchical carbon shells. The incorporation of iron-nitrogen in cellulose-derived biochars through a time-saving and energy-efficient microwave activation procedure may have potential applications in ORR.

Summary: This study demonstrates the growth of CsPbBr3 nanoparticles on semiconducting graphene oxide and conductive few-layer graphene surfaces, showing different interfacial charge transfer behaviors. The rate constant of charge transfer can be modulated by controlling the composition ratio of graphene oxide and few-layer graphene. The relationship between CO2 to CH4 conversion rate and charge transfer rate differs between the graphene oxide-based and few-layer graphene-based nanoheterostructures. This work provides important insights for the design of perovskite-graphene based nanoheterostructures with remarkable performance for solar-driven CO2 conversion.
