Abstract Supported Pt catalysts play a significant role in the selective hydrogenation of bio-derived chemicals. In this study, the typical MAX phase of Ti3AlC2 was used as the precursor to prepare Pt catalysts in one pot. Introduction of glucose as the hydrochar resource, a series of hydrochar-modified Pt catalysts were developed with different hydrochar contents. Characterizations of XRD, TEM, SEM, XPS and ICP were employed to analyze catalysts crystal phases, Pt particle size and distribution, morphologies, chemicals states of key elements and Pt real content. These catalysts were evaluated in the selective hydrogenation of bio-derived model chemicals such as phenol and furfural to investigate catalytic performances. The results demonstrated that the hydrochar-modified catalysts of Pt/Ti3AlxC2Ty-glucose improved catalytic activity, selectivity, or stability, as compared with Pt/Ti3AlxC2Ty. The possible reasons are due to the adsorption effect of hydrochar surface functional oxygen-containing groups, which enrich reactants and boost reaction kinetics, meanwhile, the hydrochar stabilizes Pt NPs by reducing aggregation to enhance stability.
