Abstract

This study employed the hydrothermal method to dope Mn into Sn₃O₄, which was then combined with g-C₃N₄ through calcination to prepare an II-type Mn-Sn₃O₄-x/CN composite photocatalyst. The impact of Mn-Sn₃O₄ loading on the photocatalytic performance was discussed. The synthesized composite catalysts exhibited remarkable hydrogen production performance under visible light, with Mn-Sn₃O₄-10/CN demonstrating the highest performance. Characterization techniques confirmed the successful preparation of the catalysts, and the light absorption capacity, charge separation and transport efficiency of Mn-Sn₃O₄-10/CN are significantly improved compared to catalysts with other ratios. This study developed a Mn-Sn₃O₄-x/CN composite catalyst with high stability and good hydrogen production rate. It provides further directions for the research of g-C₃N₄-based composite catalysts.

期刊介绍： The aim of the journal is to provide a respectful outlet for ''sound science'' papers in all research areas on surfaces and interfaces. We define sound science papers as papers that describe new and well-executed research, but that do not necessarily provide brand new insights or are merely a description of research results. Surfaces and Interfaces publishes research papers in all fields of surface science which may not always find the right home on first submission to our Elsevier sister journals (Applied Surface, Surface and Coatings Technology, Thin Solid Films)
