Summary: This study systematically investigates the C-H bond activation mechanism on Pt/MgO catalyst with O-2, O-H2O, and CO2. It is found that dry reforming of CH4 (DRM) exhibits weaker activity compared to reforming or partial oxidation of CH4. Pressure dependence shows that CO has negligible effect, suggesting the involvement of CO2 in CH4 activation as a whole molecule. The reaction between adsorbed CH4 and CO2 to form formate and methyl species is kinetically relevant. Experimental results confirm that both CO2 and CH4 derivatives are the most abundant surface intermediates.

Summary: Electrochemical CO2 reduction (CO2R) is a method to close the carbon cycle for chemical synthesis. The research has mainly focused on ambient pressure CO2, but industrial CO2 is usually pressurized and in dissolved form. By studying the effects of pressure on CO2R, the researchers found that higher pressure leads to increased formate selectivity. They further enhanced this pressure-mediated effect by functionalizing the surface of a Cu cathode with a proton-resistant layer. This work highlights the potential of using industrial CO2 as a feedstock for sustainable chemical synthesis.

Summary: Reversible CO2 capture and release under practical conditions is achieved using a single-crystalline guanidinium sulfate-based clathrate salt. The salt has high CO2 density and capacity, and the captured CO2 can be released through moderate means of pressure or temperature stimulation, while the salt is ready for another cycle. The clathrate is selective to CO2 due to specific electrostatic interaction with guanidinium cations, providing a promising avenue for future carbon capture and storage technologies.
