N掺杂活性炭负载Pd催化对甲酰基苯甲酸选择性加氢
N-doped activated carbon-supported Pd catalyst for selective hydrogenation of 4-carboxybenzaldehyde
摘要
Abstract
The N-doped activated carbon-supported Pd catalyst(Pd/WH-C)was prepared by using an equal volume impregnation method,and were characterized by N2 adsorption-desorption,FTIR,SEM,TEM,XRD,XPS,and H2-TPR.Pd/WH-C catalyst was used for the selective hydrogenation of 4-carboxybenzaldehyde(4-CBA),and its catalytic performance was compared with that of commercial Pd/C catalyst.The results show that N doping increases the specific surface area and mesoporous volume of activated carbon,improves the dispersion of Pd nanoparticles,enhances the interaction between Pd nanoparticles and activated carbon,and effectively prevents loss and sintering of Pd nanoparticles.The experimental results show that under the reaction conditions of 280℃,7.7 MPa,1 h,the initial conversion of 4-CBA on Pd/WH-C reaches 97.5%,while after six cycles,there is a decrease in conversion by 38.4 percentage points,which outperforms commercial Pd/C catalysts,indicating a good stability of Pd/WH-C.关键词
