Special Issue Information

Dear Colleagues,

The challenges of climate change, fossil energy crisis, and environment protection have significantly affected our society worldwide. Carbon neutrality to control global warming and climate change has received an increasing amount of interest among governments and researchers worldwide. Sustainable photocatalysis in aid of solar energy is playing an important role in solving these problems. Catalytic CO2 conversion to clean fuels and chemicals with renewable energy is the reliable route to reduce atmospheric carbon. Additionally, photocatalytic pollutant removal is considered a potential route to keep the environment clean without increasing the carbon burden. Accordingly, in this Special Issue, breakthroughs and recent advances in CO2 conversion, and pollutant removal with photocatalytic processes will be included.

Both type II and Z schemes can explain the charge transfer behavior of the heterojunction structure well, but the type of heterojunction structure formed between bismuth vanadium oxide and carbon nitride still has not been clarified. Herein, we rationally prepared bismuth vanadium oxide with {010} and {012} facets predominantly and carbon nitride as a decoration to construct a core-shell structure with bismuth vanadium oxide wrapped in carbon nitride to ensure the same photocatalytic reaction interface. Through energy band establishment and radical species investigation, both {010} and {012} facets dominated bismuth vanadium oxide/carbon nitride composites exhibit the type II heterojunction structures rather than the Z-scheme heterojunctions. Furthermore, to investigate the effect of type II heterojunction, the photocatalytic tetracycline degradations were performed, finding that {010} facets dominated bismuth vanadium oxide/carbon nitride composite demonstrated the higher degradation efficiency than that of {012} facets, due to the higher conduction band energy. Additionally, through the free radical trapping experiments and intermediate detection of degradation products, the superoxide radical was proven to be the main active radical to decompose the tetracycline molecules. Therein, the tetracycline molecules were degraded to water and carbon dioxide by dihydroxylation-demethylation-ring opening reactions. This work investigates the effect of crystal planes on heterojunction types through two different exposed crystal planes of bismuth vanadate oxide, which can provide some basic research and theoretical support for the progressive and controlled synthesis of photocatalysts with heterojunction structures.
