Summary: Constructing photocatalysts with excellent visible light utilization efficiency and high-efficiency photo-generated charge transfer rate is crucial for the photodegradation of organic pollutants in wastewater. In this study, oxygen-doped graphitic carbon nitride (g-C3N4) was prepared and used as a responsive material for a wide range of visible light. CdS nanoparticles were then anchored onto the g-C3N4 to form a Z-scheme heterojunction, which facilitated interfacial charge separation. The results showed that the oxygen-doped g-C3N4/CdS-3 displayed a significantly higher degradation rate for 2-chlorophenol compared to g-C3N4.

Summary: This study developed a photocatalytic additive with high activity by compounding non-toxic TiO2 and cost-effective g-C3N4, and incorporated it into PAN to prepare a photodegradable PAN material. The results showed that the PAN chain could be almost fully degraded within 90 hours under simulated sunlight in the absence of microorganisms. The degradation mechanism involved the breaking of bonds by radicals and subsequent oxidation. This design strategy may provide new insights for the production and degradation mechanism of photodegradable polymers.

Summary: We demonstrate that the electrochemically corroded thick nitrogen-doped carbon (N-C) layer encapsulated Pt/C catalyst exhibits high activity and ultrahigh stability for methanol oxidation and oxygen reduction reactions. The encapsulation of thick N-C layers initially results in low activity, but after an aging corrosion process, the activities increase significantly and remain stable. The catalyst also shows high power densities and maintains stability in an acidic membrane fuel cell. The corrosion of the thick N-C layer leads to the formation of micropores, which enhance mass transport and protect Pt particles, thereby improving activity and stability.

Summary: Exploiting non-noble metallic cocatalysts is important for photocatalytic H2 production. In this study, metallic 1T-rich MoS2 nanoparticles were embedded in C3N4 hollow spheres using an in-situ transformation method. The embedded hollow sphere structure enhances heterojunction interaction and the 1T-rich MoS2 cocatalyst promotes electron transfer and improves photogenerated carrier separation and transmission, leading to enhanced H2 production. The CN/MoS2-1 catalyst exhibits significantly improved H2 production rate (441.3 μmol g-1 h-1) and maintains outstanding stability, suggesting potential for future catalyst-cocatalyst system design to enhance photocatalytic H2 production.

Summary: Photocatalysis and piezocatalysis are important catalytic processes widely used in the fields of energy and environmental restoration. Photocatalysis is limited by the rapid recombination of electron-hole pairs, while piezocatalysis can achieve high-efficiency energy conversion through mechanical energy. Piezo-photocatalysis can combine the advantages of the two to improve catalytic efficiency, but there is still a vast knowledge gap for its design, applications, and prospects.

Summary: The construction of Bi2O4 @SnS 2D/1D hierarchical heterojunction with excellent light harvesting ability has significantly enhanced the photocatalytic degradation of tetracycline under visible light. The degradation rate constant of tetracycline over Bi2O4@SnS was 3.3 and 10.6 times higher than that over Bi2O4 and SnS, respectively. The enhanced photocatalytic activity can be attributed to the successful construction of the heterojunction and the increased specific surface area and broadened visible-light absorption region.
