The performance of Cu catalysts is heavily dependent on the Cu active center, which is highly influenced by the preparation method and support properties. Therefore, it is essential to understand the regulation of Cu active center and its effect on the catalytic performance to design efficient Cu catalysts. In this proposal, we aim to investigate the Cu active center regulation in CuY catalysts (where Y represents the support material) and its correlation with the catalytic activity and selectivity in the hydrogenation of nitrobenzene.Objectives:1. To synthesize CuY catalysts with different Cu loadings and support materials.2. To characterize the structural and surface properties of the CuY catalysts using various techniques such as XRD, BET, TEM, XPS, and DRIFT.3. To evaluate the activity and selectivity of the CuY catalysts in the hydrogenation of nitrobenzene under various reaction conditions.4. To investigate the correlation between the Cu active center, surface properties, and catalytic performance of the CuY catalysts.Methodology:1. Synthesis of CuY catalysts: CuY catalysts will be synthesized using the impregnation method with varying Cu loadings (1-5 wt.%) and different support materials (zeolite, silica, alumina).精品文档---下载后可任意编辑2.
