[1E08] Hydroxyapatite supported polyvinylpyrrolidone-capped CuPd bimetallic catalyst for highly selective γ-butyrolactone via hydrogenation of succinic acid
The highly selective hydrogenation of succinic acid (SA) to γ-butyrolactone (GBL) over the hydroxyapatite supported polyvinylpyrrolidone (PVP)-capped CuPd nanoparticles, denoted as CuxPdy-PVP/HAP (x+y = 0.1 mmol), is studied. While the bimetallic alloying catalyst at optimal metal ratio can accelerate the reaction affording 94% yield of GBL with 99% selectivity, the monometallic catalysts showed relatively lower activities. Furthermore, owning superior reactivity at mild H2 pressure (1–8 MPa) affording 62–94% GBL yield, while remaining its acitivity for 6 recycle runs make this catalyst potentially capable for hydrogenation of oxygen-rich biomass resources from laboratory to industrial scale.
