The matching of HER/OER process is a significant issue for photocatalytic overall water splitting. The MnO_x/g-C₃N₄/CdS/Pt hollow core–shell heterojunction is prepared via a continuous chemical-annealing-photoreduction method. There, the as-prepared MnO_x/g-C₃N₄/CdS/Pt composite exhibits an obvious HER enhancement of about ~ 80 folds than single CdS, a remarkable overall water splitting performance of about ~ 1303.39(H₂)/641.60(O₂) μmol∙g⁻¹∙h⁻¹, and a decent photocatalytic stability, which can be mainly ascribed to that, with the remarkable matching of HER/OER process, the Pt nanoparticles with quickly charge carriers transport can accept/diffuse the photo-generated electrons into water, the high chemical valance manganese ions can excite the hole­related species and accelerate the H₂O₂ decomposition, the formation of g-C₃N₄/CdS heterojunction can promote photo-generated carriers separation/transport via the appropriate potential, and the hollow structure can increase the HER/OER active sites, solar efficiency and stability.

HER / OER工艺的匹配是光催化总水分解的重要问题。MnO _x / gC ₃ N ₄ / CdS / Pt中空核-壳异质结是通过连续化学退火-光还原法制备的。在那里，所制备的MnO _x / gC ₃ N ₄ / CdS / Pt复合材料比单CdS表现出明显的HER增强约80倍，显着的总水分解性能约为1303.39（H ₂）/641.60（O ₂）μmol∙g ^-1 ∙h ^-1以及良好的光催化稳定性，这主要归因于HER / OER工艺的显着匹配，具有快速载流子传输能力的Pt纳米颗粒可以将光生电子接受/扩散到水中，这是化学价高的锰离子可以激发空穴相关的物种并加速H ₂ O _2的分解，gC ₃ N ₄ / CdS异质结的形成可以通过适当的电势促进光生载流子的分离/传输，中空结构可以提高HER / OER活性地点，太阳能效率和稳定性。
