Preparation of two-dimensional carbon nanomaterials and their application in the selective oxidation reaction of benzyl alcohol

本文围绕非金属纳米碳材料的制备及其在苯甲醇选择性氧化反应中的性能调控和机理开展研究。选择富含-OH的微晶纤维素(α-cellulose)为前驱体,在较低的温度(500~700℃)下热解制备了二维纳米碳材料。研究发现,该材料在90℃下实现高效的苯甲醇选择氧化,转化率和选择性分别达到92.1%和93.7%。本研究为开发高效催化剂和促进废弃物资源化利用提供了技术支持,并对碳材料在催化领域的应用具有重要的指导意义。

This study focuses on the preparation of non-metallic carbon nanomaterials and their performance modulation and mechanism in the selective oxidation reaction of benzyl alcohol.α-cellulose,which is rich in hydroxyl groups,was selected as the precursor and subjected to pyrolysis at low temperatures(500-700℃)to produce two-dimensional nanocarbon materials.It was found that the catalyst exhibited excellent reactivity in the selective oxidation of benzyl alcohol,achieving a conversion rate of 92.1%and a selectivity of 93.7%at 90℃.In summary,this research findings offer technical support for the development of efficient catalysts and the promotion of waste resource utilization.Additionally,they provide valuable guidance for the application of carbon materials in the field of catalysis.
