Single-atom copper embedded in two-dimensional MXene toward peroxymonosulfate activation to generate singlet oxygen with nearly 100% selectivity for enhanced Fenton-like reactions

Peizhen Yang et al.

Summary: In this study, single-atom copper anchored on Ti3C2Tx MXene nanosheets (Cu-SA/MXene) was developed by molten salt etching for the generation of singlet oxygen (O-1(2)) via peroxymonosulfate (PMS) activation. The catalyst exhibited a high selectivity of 99.71% toward O-1(2) generation by activating PMS and showed outstanding catalytic activity for multiple pollutants and strong resistance to inorganic anions. The Cu single atoms with three oxygen coordination environments (CuO3) were found to be more favorable for PMS absorption and selectively adsorbed the terminal oxygen of PMS to promote the generation of SO5.-, resulting in the generation of O-1(2). A continuous-flow wastewater system with the catalyst dispersed on a poly (vinylidene fluoride) membrane showed stable catalytic activity for polycarbonate plant wastewater treatment over 8 hours.

The role of Cu1-O3 species in single-atom Cu/ZrO2 catalyst for CO2 hydrogenation

Huibo Zhao et al.

Summary: This study reports a novel copper-based catalyst with isolated active copper sites for the hydrogenation of CO2 to methanol. The Cu-1-O-3 units in the Cu-Zr catalyst are found to contribute solely to methanol synthesis, while small copper clusters or nanoparticles with Cu-Cu structural patterns are responsible for the formation of CO by-product. Additionally, the migration of Cu-1-O-3 units to the catalyst surface during the catalytic process accelerates CO2 hydrogenation. These findings extend the application potential of single-atom catalysts for thermal catalytic CO2 hydrogenation and provide insights for the design of high-performance copper-based catalysts to meet industrial demand.

On the wrong assignment of the XPS O1s signal at 531-532 eV attributed to oxygen vacancies in photo- and electro-catalysts for water splitting and other materials applications

Hicham Idriss

Summary: The XPS O1s signal mistakenly attributed to oxygen vacancies is actually due to the adsorption of water molecules on the oxide surface under ambient conditions. Surface oxygen vacancies in binary or mixed metal oxide materials or catalysts will be oxidized instantly due to the strong adsorption energy of water, making it impossible for ex-situ measurements.
