Summary: With the rapid development of economy and modern industry, serious environmental pollution and energy shortage have become major urgent challenges to the human society. Photocatalysis is a promising technology to provide green energy. However, the limitations of g-C 3 N 4 , such as fast recombination of charges, limited light response range, and weak oxidation ability, restrict its photocatalytic performance. The construction of heterojunctions with g-C 3 N 4 and other semiconductor materials can effectively address these issues and improve the photocatalytic performance.

Summary: Using semiconductor photocatalysis to convert solar energy into chemical energy is a viable strategy for addressing the energy and environmental crisis. Graphitic carbon nitride (g-C3N4) is a popular 2D photocatalyst with visible light response, low cost, and high stability, but single g-C3N4 photocatalyst has poor performance due to fast recombination of photogenerated electrons and holes. Hybridizing g-C3N4 with other 2D materials to construct 2D/2D heterojunction photocatalysts improves this limitation by offering large contact area and plentiful channels for the migration and separation of photogenerated charge carriers, inheriting the strengths of 2D structure such as high specific surface area and abundant active sites.

Summary: The self-assembled core-shell BixY1-xVO4@g-C3N4 (BYVO@PCN) photocatalyst was synthesized by in-situ polycondensation of melamine on the surface of BixY1-xVO4, forming a core-shell structure. The excessive unpaired O atoms on the surface of BYVO played a key role in the formation of the core-shell structure by absorbing intermediate products of polycondensation. Furthermore, BYVO@PCN achieved photocatalytic pure water splitting into H2 and O2 at a rate about 5 times higher than BixY1-xVO4, and solved the problem of low O2 evolution in pure water splitting by PCN. Additionally, BYVO@PCN formed an S-scheme heterojunction, significantly enhancing the separation of charge carriers.
