Easily recyclable photocatalysts hold great potential in the field of photocatalysis. Guided by rational theoretical predictions, this study designs a novel tetrapod-like CdZnS/NiCoB (CZS/NCB) Schottky heterojunction with magnetic and photothermal properties, and demonstrates its excellent photocatalytic hydrogen evolution performance. Under the combined effects of the photothermal properties and the Schottky heterojunction, the photocatalytic hydrogen evolution rate extraordinarily reaches 108.39 mmol g h after 3 h of visible light irradiation, which is 4.69 times that of pure CZS. Additionally, photocatalytic hydrogen evolution tests conducted using infrared thermography and alternating visible and visible plus infrared light irradiation have confirmed the material's outstanding photothermal properties. In-depth density functional theory (DFT) calculations reveal potential charge transfer pathways and confirm the formation of the Schottky heterojunction. This work provides guidance for the rational construction of magnetic recoverable photocatalysts with practical application.
易于回收的光催化剂在光催化领域具有巨大潜力。在合理的理论预测指导下，本研究设计了一种具有磁性和光热性质的新型四足状CdZnS/NiCoB（CZS/NCB）肖特基异质结，并展示了其优异的光催化析氢性能。在光热性质和肖特基异质结的共同作用下，可见光照射3小时后，光催化析氢速率异常达到108.39 mmol g⁻¹ h⁻¹，是纯CZS的4.69倍。此外，使用红外热成像以及交替的可见光和可见光加红外光照射进行的光催化析氢测试证实了该材料出色的光热性质。深入的密度泛函理论（DFT）计算揭示了潜在的电荷转移途径，并证实了肖特基异质结的形成。这项工作为合理构建具有实际应用价值的磁性可回收光催化剂提供了指导。
