S-scheme heterojunctions have become a hot topic in photocatalysis. Copper (Cu) compounds are versatile family of photocatalytic materials, including oxides (CuO, Cu2O), binary (CuBi2O4, CuFe2O4), sulfides (CuxS, (1 ≤ x 2)), selenides (CuSe), phosphides (Cu3P), metal organic frameworks (MOFs), etc. These materials characterized by narrow bandgaps, large absorption coefficients, and suitable band positions. To further increase the efficiency photoinduced charge separation, Cu-based widely integrated into exploited for hydrogen evolution reaction (HER), CO2 reduction, H2O2 generation, N2 fixation, pollutant degradation. This review comprehensively discusses recent progress heterojunctions, highlights their considerable potential targeted applications sustainable energy conversion, environmental remediation, beyond. The fundamentals transfer, design principles verification tools summarized. Then, describes categorized according to chemical composition, integration applications. In particular, implications transfer mechanism on promoting catalytic activity selected systems analyzed. Finally, current limitations outlooks provided motivate future studies developing novel advanced photocatalysts with high performance studying underlying mechanisms.

Graphene quantum dots (GQDs) show significant promise as antibacterial agents, but their application is hindered by several limitations, including potential cytotoxicity at high concentrations, well concerns regarding aggregation and reusability. In this study, sodium titanate (NTO) ultralong nanotubes were utilized both a photocatalyst support for GQDs. The NTO/GQDs heterojunction was formed embedding GQDs nanoplates onto the walls of NTO nanotubes. This integration significantly improved visible light absorption enhanced separation transfer electron–hole pairs, leading to an efficient photocatalytic process. NTO/GQD-8 self-supporting membrane composed these demonstrated outstanding efficiency (99.99%) against E. coli exhibited remarkable cycling stability. Radical scavenging experiments revealed that ∙OH e− primary reactive species driving Notably, NTO/GQDs-8 distinct outcomes. After treatment with NTO/GQDs-8, cells completely fragmented, no intact cell structures remaining due synergy effect GQDs’ physical cutting during treatment.

Photocatalysis represents a sustainable strategy for addressing energy shortages and global warming. The main challenges in the photocatalytic process include limited light absorption, rapid recombination of photo-induced carriers, poor surface catalytic activity reactant molecules. Defect engineering photocatalysts has been proven to be an efficient approach improving solar-to-chemical conversion. Sulfur vacancies can adjust electron structure, act as reservoirs, provide abundant adsorption activate sites, leading enhanced activity. In this work, we aim elucidate role sulfur reactions valuable insights high-efficiency with future. First, delve into fundamental understanding photocatalysis. Subsequently, various strategies fabricating are summarized, along corresponding characterization techniques. More importantly, mechanism, focusing on three key factors, including charge transfer, reaction, is discussed detail. Finally, future opportunities vacancy photocatalysis identified.
