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.

To address the limitations of carbon nitride in photocatalysis, we propose constructing a three-dimensional interwoven SiC/g-C3N4 composite structure. Utilizing strong microwave-thermal conversion characteristics SiC whiskers, localized "hot spots" are generated, which induce rapid thermal gradients, promoting polymerization urea and situ formation network. This unique structure strengthens interaction between these two components, creates multiple electron transport pathways, enhances CO2 adsorption, effectively improves charge separation while reducing photogenerated carrier recombination. The CO generation rate catalysts under simulated sunlight approaches 17.78 μmol g–1h–1 with 93.28% selectivity, three times more than pure g-C3N4. These findings offer innovative strategies for designing multiscale structures to enhance photocatalytic reduction. They also contribute development sustainable energy environmental applications.
