Precise regulation of Mo2N–TiO2 deposited Pt nanoparticles induced synergistic effect for the hydrogenation of cinnamaldehyde.

The amalgamation of an appropriate cocatalyst is a proficient technique to expand the efficacy of precious Pt-based catalytic materials. In this study, Mo 2 N–TiO 2 with regularly distributed Mo 2 N particles were simply prepared for the deposition of precious Pt nanoparticles (NPs). Numerous techniques were implemented to thoroughly explore, how synthesis method influence the bulk structural, interfacial and cata1ytic features of the as-prepared 3 wt%Pt/TiO 2 and 3 wt%Pt/Mo 2 N–TiO 2 catalytic materials. The catalytic results obviously show that the 3 wt%Pt/Mo 2 N–TiO 2 catalyst has exceptional hydrogenation performance when compared to 3 wt%Pt/TiO 2 catalyst. The 3 wt%Pt/Mo 2 N–TiO 2 catalyst displayed high conversion (72.4 %) of cinnamaldehyde (CAL) with a maximum selectivity (82.1 %) towards C O bond. The excellent hydrogenation performance is attributed to the synergistic interaction taking place between Pt NPs and Mo 2 N entities of 3 wt%Pt/Mo 2 N–TiO 2. Also, the enhanced standardized dispersal of Pt NPs on the Mo 2 N–TiO 2 surface causes more exposed Pt0 sites on the 3 wt%Pt/Mo 2 N–TiO 2 surface, which is productive for the improved activation and conversion of C O bond of CAL to yield COL. In addition, the 3 wt%Pt/Mo 2 N–TiO 2 catalyst retained its higher catalytic activity for consecutive five successive rounds without substantial loss in either conversion or selectivity. [Display omitted] • Mo 2 N–TiO 2 were synthesized through one pot synthetic procedure. • Pt NPs was uniformly dispersed over Mo 2 N–TiO 2 by a simple polyol method. • The Pt/Mo 2 N–TiO 2 catalyst exhibits good catalytic activity for CAL hydrogenation. • Pt has synergistic effect with Mo 2 N for the selective hydrogenation of CAL.
