2D vanadium carbide (V2CTx) MXene supported NiIn intermetallic compounds for the selective hydrogenation of cinnamaldehyde to cinnamyl alcohol
NiIn intermetallic compounds are constructed over V2CTx MXene for the selective hydrogenation of cinnamaldehyde (CAL) to cinnamyl alcohol (COL). Ni4In/V2CTx demonstrated a conversion rate of 93.6% for CAL, with a high selectivity of 77.4% for COL. The COL yield of Ni4In/V2CTx is much greater than that of Ni4In, Ni/V2CTx, and Ni4In/Al2O3. Moreover, the V2CTx support is the key to the formation of NiIn intermetallic compounds, which effectively inhibit the oxidation of metallic Ni. NiIn metal particles are uniformly distributed on the surface of V2CTx, increasing the metal‒support interaction. Electron-deficient metallic Ni and In inhibit the hydrogenation of the C=C bond. Furthermore, the introduction of In provides more abundant and stronger Lewis acid sites, facilitating the adsorption of C=O bonds and thereby enhancing the selectivity for COL.
