The advancement of exceptionally effective catalysts that are photostable is significantly important for the sustainable conversion of solar energy into hydrogen. Combining the strengths of NaNbO3 and CdSe in a fabricated heterojunction has been pursued in photocatalysis to enhance the performance while addressing CdSe’s stability. In this study, nanoparticle-CdSe was deposited on NaNbO3 nanorods via hydrothermal method, and the optimal composite ratio of CdSe/ NaNbO3 heterojunction achieved a p

Against the backdrop of energy scarcities and ecological concerns, the process of photocatalytic hydrogen evolution emerges as a critical method for transforming solar energy into chemical energy. Central to this technology is the crafting of photocatalysts that are not only efficient and durable but also economically viable. The key to creating photocatalysts that boast superior hydrogen production capabilities lies in enhancing the separation and transfer of photo-generated electrons and holes

As a typical perovskite material, NaTaO3 has been regarded as a potential catalyst for photocatalytic hydrogen evolution (PHE) process, due to its excellent photoelectric property and superior chemical stability. However, the photocatalytic activity of pure NaTaO3 was largely restricted by its poor visible-light absorption ability and rapid recombination of photogenerated charge carriers. Therefore, a covalently bonded TpBpy covalent organic framework (COF)/NaTaO3 (TpBpy/NaTaO3) heterostructure
