Summary: A general synthetic method for zinc-metallophthalocyanine (MPc) molecular layer/polyoxometalate (POM) sandwich lamellar material was developed in this study, which improved the performance of CO2 reduction. The incorporation of POM prevented aggregation of MPc molecular layers and favored the exposure of active sites. The molecular layer sandwich catalyst showed superior CO2 reduction activity and achieved high CO Faradaic efficiency under dark and light conditions, with enhanced catalytic performance under external light field.

Summary: The effect of CO2 concentration, flow rate, and pressure on the performance of a CO2 electrolyzer was investigated. It was found that a lower stoichiometric ratio and higher CO2 concentration can result in higher current density. However, diluting the CO2 feed led to a decrease in current density. Pure CO2 operation showed only a minor increase in current density. Long-term operation resulted in a continuous drop in current density and an increase in electrode resistance.

Summary: The presence of 1-octanethiol in the electrolyte can enhance discharge rates of iron electrodes, but it poisons the air-electrode catalyst by adsorbing sulfur species, reducing its performance in iron-air batteries. It is recommended to avoid using sulfur-based additives in concentrations above 10 x 10(-3) mol dm(-3) for iron-air batteries.

Summary: Green hydrogen is a valuable energy source for addressing the environmental impact of fossil fuel consumption. Large-scale production of green hydrogen can be achieved using anion exchange membrane water electrolyzer (AEMWE) with highly electroactive and low-cost catalysts for hydrogen evolution reaction (HER). A novel catalyst was developed by an anhydrous etching procedure of commercial and low-cost Ni foam electrodes, which showed promising catalytic performance for HER with an onset potential close to the thermodynamic value. Further investigations using differential electrochemical mass spectrometry (DEMS) and Raman spectroelectrochemistry (Raman-SEC) provided insights into the reaction kinetics and mechanism of the HER at catalysts in alkaline medium.
