The catalytic hydrodeoxygenation (HDO) of the cyclic five-membered ester gamma-valerolactone (GVL-C5H8O2) on a series of supported metal phosphide and bimetallic phosphide catalysts was studied at 0.5 MPa. Comparison of activities was based on turnover frequencies calculated from surface metal atoms determined from the chemisorption of CO at 50 °C. It was found that catalytic activity followed the order: Ni₂P/MCM-41 >> CoP/MCM-41 >> Pd/Al₂O₃ ≈ MoP/MCM-41 > WP/MCM-41 in mono metallic phosphide catalyst and Ni₂P/MCM-41 > NiMo(3:1)P/MCM-41 > NiMo(1:1)P/MCM-41 > NiMo(1:3)P/MCM-41 > MoP/MCM-41 in bimetallic phosphide catalysts. On all catalysts ring opening of the lactone to produce pentanoic acid was the main initial step with subsequent hydrogenation to form pentanal. On Ni₂P/MCM-41, CoP/MCM-41 and Pd/Al₂O₃ this was followed mainly by decarbonylation to produce CO and saturated C4 hydrocarbons. On MoP/MCM-41 and WP/MCM-41 the principal subsequent step was deoxygenation to produce unsaturated C5 hydrocarbons. The bimetallic phosphide catalysts presented performance as pure compounds depending on the metal ratio, but slightly enhanced production of C5 hydrocarbons. A possible reaction network is proposed based on product selectivity.
