摘　　要：光电化学(PEC)水分解是一种利用太阳能制氢的先进技术,被广泛认为是与目前工业上其他制氢技术比较更具有潜力和环境友好性的方法。粒子转移法制备的颗粒光电极因其优越的光电化学性能表现,被认为是一种太阳能分解水器件光电极的有效制备方法之一。通过探索制备稳定和高效的颗粒型光阴极的研究,阐述光阴极在光电化学分解水中的关键问题及其在实现太阳能水分解中的潜在应用。通过采用粒子转移法成功制备了颗粒型CuFeO_(2)光阴极,并将其用于太阳能水还原反应。实验结果表明,在酸性缓冲液测试条件下,CuFeO_(2)光阴极表现出较高的光电流密度和稳定性。此外,将Pt作为助催化剂负载在CuFeO_(2)光阴极表面,光阴极的光电流密度提高近40倍。Photoelectrochemical(PEC)water splitting is an advanced technology for hydrogen production from solar energy,which is widely recognized as a more promising and environmentally friendly method in comparison with other hydrogen production technologies that are currently available in industry.Particulate photoelectrodes prepared by the particle transfer method are considered one of the effective preparation methods for photoelectrodes of solar decomposition water devices due to their superior photoelectrochemical performance.This study explored the preparation of stable and efficient particulate photocathodes and illustrated the key issues of photocathodes in the photoelectrochemical decomposition of water and their potential applications in realizing solar water splitting.The particle-type CuFeO_(2) photocathode was successfully prepared by using the particle transfer method and used in the solar water reduction reaction.The experimental results showed that the CuFeO_(2) photocathode exhibited high photocurrent density and stability under acidic buffer test conditions.In addition,by loading Pt as a co-catalyst on the surface of the CuFeO_(2) photocathode,the photocurrent density of the photocathode was increased by nearly fourty times.
