Because of its excellent optical and electrical properties, SnS2 has been widely used in solar cells, photocatalysis, and other fields. Here, a Fe-doped SnS2 nanoflower with room temperature ferromagnetism was constructed to investigate the effect of Fe doping and an external magnetic field on the photoelectric catalytic hydrogen production of water splitting. Enhanced visible-light absorption and electrical conductivity were observed in Fe-doped SnS2, thereby enhancing its photoelectrocatalytic hydrogen production performance. Moreover, the application of an external magnetic field leads to a negative potential shift, resulting in a decreased photocurrent response for Fe-doped SnS2. In addition, the first-principles calculations also indicate the origin of the magnetic properties and improved catalytic activity of a SnS2 nanoflower with Fe doping.

用于磁可调光电催化析氢反应的 Fe 掺杂 SnS2 纳米花
SnS 2因其优异的光电性能而被广泛应用于太阳能电池、光催化等领域。在此，构建了具有室温铁磁性的Fe掺杂SnS 2纳米花，以研究Fe掺杂和外部磁场对光电催化水分解产氢的影响。Fe掺杂的SnS 2可见光吸收和电导率增强，从而增强其光电催化产氢性能。此外，施加外部磁场会导致负电势漂移，从而导致Fe掺杂SnS 2的光电流响应降低。此外，第一性原理计算还表明了Fe掺杂的SnS 2纳米花的磁性起源和催化活性的提高。
