摘要

采用三聚氰胺与三聚氰胺反应制备了分散性高、粒径均匀的纳米铑，并在载体上稳定形成了非均相催化剂Rh/CAM。该催化剂在苯酚及其同系物的加氢反应中表现出较高的活性。在无溶剂条件下，在1.0 MPa的氢气压力和60℃的温度下，苯酚在1 ~ 2 h内定量转化为环己醇。催化剂在连续十次循环后保持活性。研究了温度、压力和溶剂对催化剂活性、选择性和稳定性的影响。

Hydrogenation of phenol on rhodium nanoparticles stabilized on a support formed by the reaction of melamine and cyanuric chloride

The heterogeneous catalyst Rh/CAM, which was formed by highly dispersed uniform-size rhodium nanoparticles stabilized on a support prepared by the reaction of melamine and cyanuric chloride, was prepared. The catalyst showed high activity in the hydrogenation of phenol and its homologues. The quantitative conversion of phenol to cyclohexanol occurs within 1–2 h at a hydrogen pressure of 1.0 MPa and a temperature of 60 °C in the absence of a solvent. The catalyst maintains its activity after a series of ten consecutive cycles. The influence of the temperature, pressure, and solvent on the activity, selectivity, and stability of the operation of the catalyst was studied.
