A novel ZSMo core-shell nanowire photocatalyst was synthesized by ion exchange and hydrothermal methods. The photocatalytic activity of ZSMo nanocomposites was evaluated via photolysis of water to produce hydrogen. The results showed that the hydrogen generation rate of ZSMo-0.1 core-shell nanowires was the highest, which was about 23 times that of pure ZnO. The improvement of photocatalytic activity was attributed to the formation of type II and ternary heterojunctions, which enable the rapid separation of photo-induced charge carriers and capture more light radiation. It was confirmed by UV–Vis diffuse reflectance spectroscopy, electrochemical impedance spectroscopy and photocurrent analysis.

通过离子交换和水热法合成了新型的ZSMo核壳纳米线光催化剂。通过水的光解产生氢气来评估ZSMo纳米复合材料的光催化活性。结果表明，ZSMo-0.1核壳纳米线的产氢率最高，约为纯ZnO的23倍。光催化活性的提高归因于II型和三元异质结的形成，这使得能够快速分离光诱导的电荷载体并捕获更多的光辐射。紫外可见散射光谱，电化学阻抗谱和光电流分析证实了这一点。
