Pd-based nanostructures have high catalytic activity and good light trapping ability for photothermal catalysis. In this work, PdFe nanosheets (NSs) were synthesized through a hydrothermal method and efficiently catalyzed ethylene glycol electrooxidation reaction (EGOR). Under the irradiation of light, the mass activity of EGOR enhanced 1.78 times (from 4.02 to 7.17 A mg⁻¹) comparing with no light, which was 18 times higher than commercial Pd/C. The high activity is attributed to the combination of high photothermal conversion efficiency and the exposure of high energy facet (111) of PdFe NSs. The effects of Pd/Fe ratio, light intensity, and wavelength were investigated.

钯基纳米结构具有较高的催化活性和良好的光热催化捕光能力。在这项工作中，通过水热法合成了PdFe纳米片（NSs），并有效地催化了乙二醇电氧化反应（EGOR）。在没有光的情况下，EGOR的质量活性提高了1.78倍（从4.02至7.17 A mg ^-1），比无光Pd / C高18倍。高活性归因于高光热转换效率和PdFe NSs高能面（111）的暴露。研究了钯/铁比，光强度和波长的影响。
