High-Loading Cu Single-Atom Engineering on g-C₃N₄ for Visible-Light CO₂ Photoreduction.

The incorporation of metal single atoms into carbon nitride (CN) has emerged as a promising strategy for photocatalytic CO₂ reduction under visible light. However, achieving high single-atom loading and unraveling the precise role of active metal centers in CO₂ conversion remain formidable challenges. Herein, an ultrasound-assisted coordination exchange strategy is reported that enables the high-loading of Cu single atoms on CN.

Regulating Atomically-Precise Pt Sites for Boosting Light-Driven Dry Reforming of Methane.

Light-driven dry reforming of methane is a promising and mild route to convert two greenhouse gas into valuable syngas. However, developing facile strategy to atomically-precise regulate the active sites and realize balanced and stable syngas production is still challenging. Herein, we developed a spatial confinement approach to precisely control over platinum species on TiO surfaces, from single atoms to nanoclusters.

Single-Atom Alloys Materials for CO and CH Catalytic Conversion.

The catalytic conversion of greenhouse gases CH and CO constitutes an effective approach for alleviating the greenhouse effect and generating valuable chemical products. However, the intricate molecular characteristics characterized by high symmetry and bond energies, coupled with the complexity of associated reactions, pose challenges for conventional catalysts to attain high activity, product selectivity, and enduring stability. Single-atom alloys (SAAs) materials, distinguished by their tunable composition and unique electronic structures, confer versatile physicochemical properties and modulable functionalities.

Contrastive Study of the Foaming Properties of N-Acyl Amino Acid Surfactants with Bovine Serum Albumin and Gelatin.

A detailed study on the foamability, foam stability, foam liquid-carrying capacity, and foam morphology of two N-acyl amino acid surfactants with bovine serum albumin (BSA) and gelatin were performed by foam scanning. The results showed that the foamability of the mixed system increased gradually and then tended to be stable with increasing surfactant concentration. The foamability of the high-concentration BSA system was stronger than that of the low-concentration BSA system.
