材料學院宋浩杰教授團隊在材料學國際頂級期刊《Advanced Materials》上發(fā)表最新成果

近日，我校材料科學與工程學院（文物保護科學與技術(shù)學院）碳基功能材料創(chuàng)新團隊在光催化研究領(lǐng)域取得重要進展，相關(guān)研究成果以“Photocatalytic H₂O₂ Generation Reaction with A Benchmark Rate at Air-Liquid-Solid Joint Interfaces”為題，發(fā)表于國際頂級期刊《Advanced Materials》（IF=29.4）上。我校為論文第一通訊單位，碩士研究生嚴仕偉（現(xiàn)為華南理工大學博士生）為第一作者，陜西科技大學李永副教授、昆士蘭科技大學許景三副教授和陜西科技大學宋浩杰教授分別為論文通訊作者。該工作的發(fā)表提高了我校在光催化材料領(lǐng)域的國際影響力。

電荷復合速度快、雙電子氧還原反應(yīng)選擇性低、O₂擴散速率低等問題阻礙了光催化產(chǎn)H₂O₂的實際應(yīng)用?；诖耍竟ぷ鲃?chuàng)新性提出通過界面工程改善光催化過程中的傳質(zhì)障礙，構(gòu)建一種氣-液-固三相界面催化系統(tǒng)，用于從純水中高效光催化生成H₂O₂。其中，以三聚氰胺-三聚氰酸前體(MCP)和聚吡咯(PPy)超分子熱解合成花狀石墨相碳化氮（Cv-PCN）高選擇性的將O₂還原為H₂O₂。隨后將其負載的多孔材料表面并進行界面潤濕性調(diào)控構(gòu)建氣-液-固三相界面光催化體系，該體系大大降低了O₂的傳質(zhì)阻力，有效地提高了界面O₂濃度，從而極大提高了光生電子與空穴的分離效率和 H₂O₂的反應(yīng)動力學。本研究為高效光催化生產(chǎn)H₂O₂催化體系的設(shè)計提供了新的思路。
