具有成本效益的光电化学水分解需要高效且廉价的电极材料。在这里,我们报告了一种新的地球丰富的析氢光电阴极组成的CdS改性CuSbS 2合成使用低成本和高通量的解决方案的过程。所制备的CuSbS 2薄膜在大面积上是均匀的,并具有理想的微米级柱状晶结构。在AM 1.5 G模拟太阳光照射下,所制备的CuSbS 2/CdS/Pt光电阴极在中性电解液中的阴极光电流为−4.2 mA cm− 2(0 VRHE),起始电位为0.46 VRHE,阴极光电流稳定,法拉第效率接近1.此外,CuSbS 2光电阴极对可见光具有显著的响应,其光吸收边约为860 nm,因此,CuSbS 2光电阴极具有高效利用太阳辐射的潜力,而无需采用昂贵的原材料和制造技术。
Cost-effective photoelectrochemical water splitting requires highly efficient and inexpensive electrode materials. Herein, we report a novel earth-abundant photocathode for hydrogen evolution consisting of a CdS-modified CuSbS2synthesized using low-cost and high-throughput solution processes. The prepared CuSbS2thin film is homogenous over large area and exhibits desirable micrometer-sized columnar grain structure. The fabricated CuSbS2/CdS/Pt photocathode achieves a cathodic photocurrent of −4.2 mA cm−2at 0 VRHE, an onset potential of 0.46 VRHE, and a stable cathodic photocurrent with nearly unity of Faraday efficiency for hydrogen production in neutral electrolyte under AM 1.5 G simulated sunlight illumination. In addition, the CuSbS2-based photocathode possesses a significant response to visible light with an optical absorption edge around 860 nm, so that the reported CuSbS2photocathode offers potential for efficient use of solar radiation without resorting to expensive raw materials and fabrication techniques.
