Summary: This research demonstrates the successful growth of two-dimensional Cu2Te nanosheet arrays on commercial copper foils for high-efficiency CO2-to-CH4 electrocatalysis. The controllable growth of Cu2Te nanosheets with tunable sizes and thicknesses is achieved through a two-step process of chemical etching and chemical vapor deposition. The highly exposed active sites on the edges of Cu2Te nanosheets greatly promote the electroreduction of CO2 into CH4, while suppressing the hydrogen evolution reaction. The faradaic efficiency reaches about 63% at an applied current density of 300 mA cm-2 when a flow cell is used to accelerate mass transfer. These findings offer possibilities for developing scalable and energy-efficient Cu-based CO2RR electrocatalysts.

Summary: A novel two-stage integrated bubbling-transport bed reactor was proposed for post-combustion CO2 capture using K2CO3/Al2O3 sorbents. The optimal adsorption temperature range was found to be between 60 degrees C and 100 degrees C, with wider range than traditional reactors. CO2 capture efficiency increased with sorbent circulation rate and desorption temperature, while better performance was observed with air desorption gas. Water vapor step-feeding enhanced maximum CO2 capture efficiency from 87% to 96% and showed strong anti-interference ability.

Summary: This study systematically investigated the effect of thickness and morphology of Cu catalyst coatings on electrochemical CO2 reduction (ECR) performance. The results showed that electron beam (EB) Cu outperformed magnetron-sputtered (MS) Cu in terms of current density, selectivity, and energy efficiency, with 400 nm thick catalyst coatings performing the best. The superior performance of EB-Cu catalysts was attributed to their faceted surface morphology and sharper Cu/gas diffusion layer interface.

Summary: This study investigates the effect of alkali metal salt promoter K2CO3 on the cyclic performance of CaO-based sorbents. It is found that low concentrations of K2CO3 significantly improve the cyclic performance of CaO, while high concentrations reduce the CO2 uptake performance. The stability of K2CO3 is influenced by the gas environment, with partial volatilization at high temperatures leading to a decrease in K content in the samples.
