Abstract

Solar-driven photocatalytic water splitting offers a sustainable solution to the energy crisis. We developed a noble-metal-free WO₃@CdS heterojunction photocatalyst, where in situ growth of CdS nanoparticles on WO₃ nanorods accelerates charge separation. The S-scheme charge transfer mechanism driven by an internal electric field maintains robust redox activity, enabling efficient Hydrogen Evolution Reaction (HER) coupled with benzyl alcohol oxidation. This work highlights the critical role of heterojunction engineering and morphology control in high-performance photocatalysis.

无贵金属协同光催化H₂演化和苯甲醇氧化的WO₃@CdS核壳异质结

太阳能驱动的光催化水分解为能源危机提供了一个可持续的解决方案。我们开发了一种不含贵金属的WO₃@CdS异质结光催化剂，其中CdS纳米颗粒在WO₃纳米棒上的原位生长加速了电荷分离。由内部电场驱动的S-scheme电荷转移机制保持了强大的氧化还原活性，实现了高效的析氢反应（HER）和苯甲醇氧化。这项工作强调了异质结工程和形态控制在高性能光催化中的关键作用。
