Abstract

The photocatalytic activity of 2D/2D/0D heterostructures based on few-layer black phosphorus (FLBP) g-C3N4/FLBP/Co2P in the reaction of photocatalytic hydrogen formation from an aqueous solution of triethanolamine under under visible light irradiation (400 nm) was studied for the first time. An original method for the preparation of the g‑C3N4/FLBP/Co2P composite photocatalyst is proposed, which consists of the solvothermal synthesis of cobalt phosphide Co2P nanoparticles, their immobilization on the surface of FLBP, and subsequent mixing of the FLBP/Co2P heterostructure with g‑C3N4. The synthesized photocatalysts were characterized by physicochemical analytical methods (X-ray diffraction, X-ray photoelectron spectroscopy, high-resolution transmission microscopy, energy-dispersive X-ray spectroscopy). The hydrogen evolution rate in the presence of the g‑C3N4/FLBP/Co2P heterostructure was 0.09 mmol \({\text{g}}_{{{\text{cat}}}}^{{ - 1}}\) h–1, which is 25 times higher than the same characteristic for the unmodified g‑C3N4 sample. The obtained numerical values of the photocatalytic activity are at the level of the literature values.

基于经少层黑磷和磷化钴修饰的类石墨氮化碳的异质结构在氢气进化反应中的光催化活性
首次研究了基于少层黑磷(FLBP)g-C3N4/FLBP/Co2P 的 2D/2D/0D 异质结构在可见光(400 纳米)照射下从三乙醇胺水溶液中光催化制氢反应的光催化活性。提出了一种制备 g-C3N4/FLBP/Co2P 复合光催化剂的新方法,包括溶热合成磷化钴 Co2P 纳米颗粒,将其固定在 FLBP 表面,然后将 FLBP/Co2P 异质结构与 g-C3N4 混合。通过理化分析方法(X 射线衍射、X 射线光电子能谱、高分辨率透射显微镜、能量色散 X 射线光谱)对合成的光催化剂进行了表征。在 g-C3N4/FLBP/Co2P 异质结构存在下的氢演化速率为 0.09 mmol \({\{g}}_{{text\{cat}}}}^{ - 1}}\) h-1,比未修饰 g-C3N4 样品的相同特性高 25 倍。所获得的光催化活性数值与文献值持平。
