Summary: CO2 capture and utilization (CCU) is seen as a promising approach to reduce carbon emissions in the short to mid-term, but the instability of high-temperature CO2 sorption/desorption limits its potential. Therefore, developing a new sorbent/catalyst system is crucial for ensuring the high efficiency and long-term operation of CCU.

Summary: Sponge-like biochar sorbents with enhanced CO2 uptake were prepared from chitosan through dissolution, freeze-drying, and pyrolysis at different temperatures. The pyrolysis temperature influenced the textural properties of the biochar, as well as the type and amount of N-species present. XPS analysis revealed the transformation of amino groups into different N-species during pyrolysis. The biochar adsorbed higher amounts of CO2 compared to CH4 and N-2 gases, with the highest selectivity for CO2/N-2 separation observed for the sample pyrolyzed at 800 degrees C. The adsorption process was predominantly governed by physisorption, and the biochar showed tolerance to water vapor adsorption, indicating its suitability for use in moisture-rich environments.

Summary: The use of K2CO3 as a promoter enabled dynamic coke elimination reaction over Ni/Al2O3 catalysts for CO2 reforming of CH4, significantly improving coke resistance and long-term stability. The addition of K2CO3 suppressed Ni particle growth and enhanced the interaction between Ni and Al2O3, leading to improved adsorption of CO2 and facilitating the DRM process. Furthermore, K2CO3 enabled a dynamic coke elimination reaction (KCER) by enhancing catalytic reaction of disordered carbon with CO2, which is a promising low-cost approach to stabilize the performance of Ni-based catalysts in DRM reaction.

Summary: This study explores the in-situ decoration of CeO2 and Ni nanoparticles on the surface of a chromite anode in order to enhance the performance and stability of solid oxide fuel cells (SOFCs). The exsolution of CeO2 and Ni0 nanoparticles significantly improves the performance of the Ce-LCN anode under propane and H2 fuel conditions. Injecting 20% H2 in volume into CH4 has been found to effectively enhance the coking resistance of the anode, resulting in a CH4 conversion rate of approximately 85% and close to unity selectivity for CO. This study provides a viable solution for the simultaneous production of electricity and syngas from CH4 using complex perovskite SOFCs.

Summary: Combining solar light and heat in dry reforming of methane (DRM) is a promising technology for CO2 reduction and increased solar energy utilization. The mechanism of the reaction and the synergistic effects of solar light and heat in DRM are investigated using a nanoscale Ni/CeO2 catalyst. The results show that the conversion rate of CH4 increases by 39.74% and the reaction temperature is reduced by 45 degrees C under photo-thermochemical conditions. Solar light enhances the dissociation of CH4 and the production of HCOO* on the catalyst surface, leading to improved DRM performance. These findings contribute to the understanding of the synergistic effects of solar light and heat and guide the conversion of CO2 into fuel using solar energy.

Summary: High entropy oxide (HEO) is a promising catalyst support for various chemical reactions due to its tunable composition-function properties. In this study, highly dispersed rhodium nanoparticles were successfully synthesized on HEO using a one-step glycine-nitrate-based combustion method. The resulting catalyst exhibited significantly higher selectivity and activity in CO2 hydrogenation compared to rhodium nanoparticle-based catalysts. The high CO selectivity was attributed to the presence of copper and zinc in the HEO support, which weakened the *CO binding strength and formed a strong metal-support interaction.

Summary: A two-step solar thermochemical hydrogenation process for furfural upgrading is developed, which sources hydrogen directly from water and concentrated solar radiation. The catalytic performance achieved in this process is significantly higher than that of state-of-the-art catalytic hydrogenation method, with up to two-orders-of-magnitude-higher hydrogen utilization efficiency. The active sites for furfural adsorption and water dissociation are provided by a metal or reduced metal oxide, eliminating the barriers to hydrogen dissolution and the subsequent dissociation at the catalyst surface. The hydrogenation selectivity can be conveniently mediated by solvents with different polarity and metal/reduced metal oxide catalysts with varying oxophilicity. This work offers an efficient and versatile strategy for bio-oil upgrading and a promising pathway for renewable energy storage.
