中文摘要：光氧化转化可再生生物质衍生物为高附加值的化学品具有重要意义,但由于在控制氧化物种和理想的反应途径方面存在挑战,其选择性通常较低.本工作报道了利用CO2气体介导的固固相变法制备Bi2O2CO3/ZnIn2S4异质结构,用于光氧化转化生物质衍生的5-羟甲基糠醛(HMF)生成2,5-二甲酰基呋喃(DFF),其选择性高达98.1％,产率达882.6 μmol g-1 h-1.金属碳酸盐/氧化物异质界面诱导了光活性电子和空穴的有效转移,优化了表面氧的活化,促进了.OOH和空穴的协同作用,进而可以选择性地将HMF转化为DFF.本工作表明异质界面上电子-空穴对和活性氧物种的调控有助于利用可再生原料实现可持续发展.

外文摘要：The photooxidation of renewable bioderivatives into value-added chemicals is highly significant;however,it typically exhibits low selectivity owing to the challenges in controlling the oxidative species and managing the desirable reaction pathways.In this work,we used the Bi2O2CO3/ZnIn2S4 heterostructure,prepared by a CO2-mediated solid-solid phase transition,to catalyze the photooxidation of bio-derived 5-hydroxymethylfurfural(HMF)into 2,5-di-formylfuran(DFF)with a high selectivity of 98.1％and a yield rate of 882.6 μmol g-1 h-1.The metal carbonate/oxide hetero-interface enables the effective transfer of photoactive electrons and holes,optimizes surface oxygen activation,and facilitates the synergy of·OOH and holes to selectively convert HMF into DFF.The findings unravel how the tailoring and coupling of the electron-hole pairs and reactive oxygen species on het-erostructured materials can promote the usage of renewable feedstocks for sustainable development.
