Chalcostibite (CuSbS₂) semiconductor catalyst has been intensively preferred towards energy conversion processes because of its suitable bandgap, high absorption coefficient and photocatalytic activity. Herein, the photocatalytic hydrogen evolution reaction (HER) was carried out by using different shapes (Rod (R) and Dot (D)) of copper-antimony sulfides. The hydrogen evolution activities of R-CuSbS₂ and d-CuSbS₂ were investigated under the visible light irradiation by using eosin-Y (EY) dye and triethanolamine (TEOA) as photosensitizer and an electron donor, respectively. The photocatalytic HER rates of R-CuSbS₂ and d-CuSbS₂ were determined as 2140 μmolg⁻¹ h⁻¹ and 825 μmolg⁻¹ h⁻¹, respectively. R-CuSbS₂ displayed higher photocatalytic activity in comparison with d-CuSbS₂. The results of photocatalytic activity belonging to chalcostibite catalysts could be explained by efficient charge separation efficiency of 1D microrod materials.

黄铜矿（CuSbS ₂）半导体催化剂因其合适的带隙，高吸收系数和光催化活性而在能量转换过程中得到了广泛的青睐。在此，通过使用不同形状的铜-锑硫化物（Rod（R）和Dot（D））进行光催化氢释放反应（HER）。R-CuSbS的析氢活动₂和d -CuSbS ₂通过使用曙红Y（EY）染料和三乙醇胺（TEOA）作为光敏剂分别和电子给体，可见光照射下研究。R-CuSbS的光催化HER率₂和d -CuSbS ₂测定为2140μmolg^-1  h ^-1和825μmolg ^-1  h ^-1。与d -CuSbS ₂相比，R-CuSbS ₂显示出更高的光催化活性。一维微棒材料的有效电荷分离效率可以解释属于黄铜矿催化剂的光催化活性的结果。
