Summary: Bio-based porous carbon nanosheets with nitrogen doping showed excellent CO2 capture performance at both low and medium pressure. The pore size and nitrogen functional groups played important roles in the adsorption process. Slit micropores were key factors for low-pressure adsorption, while narrow mesopores were beneficial structures for medium-pressure CO2 capture. Nitrogen doping improved the charge distribution on the carbon surface and enhanced the interaction with CO2, leading to enhanced adsorption and selectivity.

Summary: In recent years, heteroatom-doped microporous carbons have attracted significant attention as emerging CO2 adsorbents. However, the role of small-sized micropores and heteroatom content on CO2 adsorption has rarely been studied. In this study, sucrose-derived porous carbons with different ratios of KOH and urea content were synthesized, and their textural features and CO2 adsorption capacity were investigated. The carbons showed remarkable surface area and micropore volume, with the optimized sample achieving a CO2 uptake of 8.19 mmol g-1. The nitrogen moieties in the carbons were found to contribute to the selective separation of CO2 from N-2 gases. In conclusion, the narrow micropores and optimal nitrogen content played a crucial role in achieving excellent CO2 adsorption performance in these carbons.

Summary: The preparation of hierarchical porous nanosilica using coal gasification fly ash as a silicon source was achieved by microwave-assisted alkaline extraction followed by hydrothermal synthesis. This method showed fast and efficient silicon extraction with less impurity metal ions. The use of specific compounds as swelling agents induced intergranular pores, which significantly improved the CO2 adsorption capacity of the nanosilica. The isosteric heat of adsorption indicated the presence of both physisorption and chemisorption in the adsorption process.

Summary: A low-cost polymerized VB-CB is designed as a hole-transporting material for inverted planar perovskite solar cells, resulting in a high power conversion efficiency of 17.58% with minimal hysteresis. Compared to PEDOT:PSS, devices with VB-CB exhibit better stability under one sun illumination, with a T80 exceeding 1000 hours. The results suggest that polymerized VB-CB is a suitable material for commercial applications in planar perovskite solar cells due to its low-cost, high efficiency, and good stability.

Summary: The effect of porous media on hydrate formation is studied in this research. Stacked porous media affect phase equilibrium depending on water activity and large surface areas, while integrated porous media can moderate phase equilibrium and transfer heat rapidly. Supersaturated metal-organic frameworks can promote hydrate formation. Porous media stabilizes hydrate crystals through hydrogen bonding, but hydroxyl radicals on silica surfaces inhibit the combination of methane and free water for more demanding phase equilibrium conditions.

Summary: In this study, a simple, green and cost-effective method was developed to synthesize N, S co-doped microporous carbon adsorbent using anthracite as the carbon source and Na2S2O3 and NaNH2 as activating and functionalized reagents. The resulting carbon adsorbent exhibited well-developed microporosity and desirable functional heteroatoms doping. The synergistic effect of these properties provided the carbon with a high CO2 adsorption capacity (3.73 mmol g-1) and good selectivity (7.80, 7.03, 5.58, 4.93 and 4.40) for binary CO2/CH4 mixture separation. The effective dynamic breakthrough behavior further demonstrated its adaptability in commercial applications.

Summary: The effects of ionic liquids (ILs) on CO2 hydrates were studied, and it was found that all five ILs could increase CO2 consumption and enhance water to hydrate conversion. [P2 4 4 4][PF6] and [P6 4 4 4][PF6] promoted CO2 hydrate nucleation, resulting in a slightly higher temperature for phase equilibrium and reduced induction times. On the other hand, [N2 2 2 2]Br, [N2 2 2 2][NTf2], and [N2 2 2 2][PF6] slowed down CO2 hydrate nucleation, leading to a lower temperature for phase equilibrium and prolonged induction times.

Summary: It is found that the combustion and oxidation performance of coal-based activated carbon (CBAC) is enhanced after adsorbing volatile organic compounds (VOCs). The thermal analysis results show that the adsorbed VOCs burn in the early stage, accelerating the oxidation and combustion of CBAC. Combustion experiments by cone calorimeter also demonstrate that the combustion rate of CBAC increases after adsorbing VOCs, with shortened ignition time, larger heat release rate, and significantly improved CO yield.
