摘要
本文采用浸渍法制备了Mo2N/BN复合载体,用沉积沉淀法负载Pt制备出Pt-Mo2N/BN催化剂,以肉桂醛加氢为探针反应,考察了贵金属活性中心种类、不同Pt载量和不同反应压力下的肉桂醛催化加氢性能.结果表明,金属Pt相较于Pd具有更高效的催化肉桂醛C=O加氢的能力,较高的Pt载量和较高的氢气压力均有利于提升催化性能.
Abstract
In this paper,Mo2N/BN composite supports were prepared by impregnation,and Pt-Mo2N/BN catalysts were prepared by a deposition precipitation method.Cinnamaldehyde hydrogenation was used as a probe reaction to investigate the catalytic performance under different types of noble metals,different Pt loadings and different reaction pressures.The results indicate that Pt metal is more efficient to catalyze the C=O hydrogenation of cinnamaldehyde compared to Pd,and higher Pt loading and hydrogen pressure are beneficial for improving catalytic performance.
