Summary: Carbon monoxide is the main product of electrochemical CO2 reduction on silver. CO poisoning poses a common challenge in catalytic systems, necessitating research on silver catalysts for electrochemical CO2 reduction. The inhibition of catalytic performance by CO, which blocks active sites, suggests that the overall process is limited by CO desorption. As a result, the catalyst self-poisons, leading to reduced rates of CO2 reduction and hydrogen evolution. Experimental investigations confirm this effect at various CO concentrations and current densities. Hence, CO poisoning must be considered when modeling electrochemical CO2 reduction using silver gas diffusion electrodes.

Summary: The reverse water gas shift (RWGS) reaction is a catalytic conversion reaction that converts carbon dioxide into a large amount of carbon dioxide. This study proposes a new and safe reaction route (CO2-MCH) to efficiently obtain carbon monoxide from carbon dioxide and methylcyclohexane (MCH). The catalytic performance of Pt-based catalysts on different supports in the CO2-MCH reaction was investigated, and it was found that the Pt/gamma-Al2O3 catalyst with high Pt dispersion, small particle size, and medium acidity exhibited good activity and selectivity. The Pt particle size was positively correlated with CO2 conversion and showed a volcano-type relationship with CO selectivity. The CO2 conversion rate was 24.7% and the CO selectivity reached 95.2% under the conditions of 350 degrees C, 0.1 MPa, and LHSV = 6 h-1.

Summary: By hybridizing TiO2 photocatalyst with CaCO3 as the wall material and using linseed oil as the core material, self-cleaning and self-repairing microcapsules were produced using in-situ precipitation. The microcapsules were evaluated for their morphology, chemical composition, thermal stability, and self-cleaning and self-repairing properties. Results showed that the microcapsules had a rough and spherical surface, along with excellent thermal stability and repeatability. Increasing the dosage of microcapsules significantly increased the degradation rate of methylene blue, while the self-repairing effect of micro-cracks became more evident. The optimal microcapsule dosage was found to be 7.0 wt%.
