材料学院宋浩杰教授团队在材料学国际顶级期刊《Advanced Materials》上发表最新成果

近日，我校材料科学与工程学院（文物保护科学与技术学院）碳基功能材料创新团队在光催化研究领域取得重要进展，相关研究成果以“Photocatalytic H₂O₂ Generation Reaction with A Benchmark Rate at Air-Liquid-Solid Joint Interfaces”为题，发表于国际顶级期刊《Advanced Materials》（IF=29.4）上。我校为论文第一通讯单位，硕士研究生严仕伟（现为华南理工大学博士生）为第一作者，mg4355电子游戏网址李永副教授、昆士兰科技大学许景三副教授和mg4355电子游戏网址宋浩杰教授分别为论文通讯作者。该工作的发表提高了我校在光催化材料领域的国际影响力。

电荷复合速度快、双电子氧还原反应选择性低、O₂扩散速率低等问题阻碍了光催化产H₂O₂的实际应用。基于此，本工作创新性提出通过界面工程改善光催化过程中的传质障碍，构建一种气-液-固三相界面催化系统，用于从纯水中高效光催化生成H₂O₂。其中，以三聚氰胺-三聚氰酸前体(MCP)和聚吡咯(PPy)超分子热解合成花状石墨相碳化氮（Cv-PCN）高选择性的将O₂还原为H₂O₂。随后将其负载的多孔材料表面并进行界面润湿性调控构建气-液-固三相界面光催化体系，该体系大大降低了O₂的传质阻力，有效地提高了界面O₂浓度，从而极大提高了光生电子与空穴的分离效率和 H₂O₂的反应动力学。本研究为高效光催化生产H₂O₂催化体系的设计提供了新的思路。
