ZnFeO is an n-type semiconductor spinel oxide with promising applications in various fields, including photocatalysis. This study reports the successful synthesis of a novel ZnFeO derivative based on Prussian Blue Analogues (PBAs) through an electrosynthesis method. To enhance photocatalytic performance, the synthesized ZnFeO was employed as a cocatalyst in p-n junction materials, specifically CuO/ZnFeO. Our findings reveal that introducing ZnFeO could significantly improve the photocatalytic activity and hydrogen (H) production rate of the CuO/ZnFeO system compared to bare CuO. This enhancement was sustained over an extended operational period, indicating the material's potential for long-term use in photocatalytic applications. The superior performance of the ZnFeO cocatalyst is attributed to its efficient charge separation and improved light absorption properties, which collectively contribute to higher photocatalytic efficiency. This study highlights the potential of PBA-based derivative ZnFeO as an effective cocatalyst in developing advanced photocatalytic systems for sustainable hydrogen production.
ZnFeO是一种n型半导体尖晶石氧化物，在包括光催化在内的各个领域都有广阔的应用前景。本研究报告了通过电合成方法成功合成了一种基于普鲁士蓝类似物（PBAs）的新型ZnFeO衍生物。为了提高光催化性能，合成的ZnFeO被用作p-n结材料（特别是CuO/ZnFeO）中的助催化剂。我们的研究结果表明，与裸CuO相比，引入ZnFeO可以显著提高CuO/ZnFeO体系的光催化活性和氢气（H）产生率。这种增强在较长的运行期内得以维持，表明该材料在光催化应用中具有长期使用的潜力。ZnFeO助催化剂的优异性能归因于其有效的电荷分离和改善的光吸收特性，这些共同促成了更高的光催化效率。本研究突出了基于PBA的衍生物ZnFeO作为开发可持续制氢先进光催化系统的有效助催化剂的潜力。
