Synthesis and performance study of visible light responsive Mn-Sn3O4/g-C3N4 heterojunction photocatalyst
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)
