“…Obtaining hydrogen energy from solar energy has been considered as one of the alternatives to current electrical energy or fossil energy, and a photocatalytic semiconductor catalyst has been reported as an indispensable bridge for the solar hydrogen energy conversion. Graphitic carbon nitride (g-CN), as a metal-free photocatalyst for the hydrogen evolution reaction, has attracted significant interest of researchers for its advantages such as good biocompatibility, the low-cost of the raw materials, and the convenient synthetic route. The practical application of g-CN, however, is still predominantly limited by the inherent shortcomings of organic semiconductors, i.e., slow charge-transport capability, fast recombination of photogenerated carriers, and excessive hydrogen overpotential. Therefore, a series of methods to modify g-CN have been reported, and loading an appropriate cocatalyst on to the surface of g-CN is one of the effective methods that can promote the transfer of carriers and lower the hydrogen overpotential. Noble metals, including Pt, Au, and Pd, have been widely believed as the cocatalyst for g-CN and exhibited excellent properties. Despite their great performance, the high price of noble metals is still an inescapable limitation that hinders the wide application of photocatalysts, which runs counter to the original intention of lowering the cost of the catalyst. In this regard, developing a new cocatalyst with low cost to replace the noble metal will benefit the actual production in the future.…”

“…The prepared hybrid structure can improve the electrons holes separation and efficiency [483]. Other metal oxides can also be used in the g-C3N4 Methylene Blue (MB), Methylene Orange (MO), and Rhodamine B (RhB) are the most commonly stable dyes in water at room temperature [461][462][463][464][465][466][467][468]. MB and RhB are toxic dyes that their high concentration can be so harmful to human and marine animal health.…”

“…Clearly, photoactivity of any efficient photocatalyst is dominantly influenced by morphology, size and architecture [ 3 , 151 ]. For example, cicada wing architectures have inspired the fabrication of a biomorphic Ag-TiO 2 photocatalyst for the degradation of methylene blue dye in 15 minutes.…”
