Catalytic conversion of biomass glycerol to lactic acid is an alternative to the conventional fermentation process starting from carbohydrate. Graphite-supported metallic Ni0 nanoparticles effectively catalyzed the hydrothermal conversion of glycerol to lactic acid in NaOH aqueous solution. Ni0 nanoparticle and NaOH synergistically catalyzed the glycerol conversion to lactic acid. When the reaction was carried out with the initial glycerol and NaOH concentrations of 1.0 and 1.1 mol L−1 at 230 °C for 3 h over Ni0.3/graphite catalyst, the selectivity of lactic acid was 92.2% at the glycerol conversion of 97.6%. The reaction activation energy, Ea, was 69.2 kJ mol L−1.
