Hydrogenolysis of glycerol over TiO₂-supported Pt-WO_x catalysts: Effects of the TiO₂ crystal phase and WO_x loading.

ABSTRACT: The selective hydrogenolysis of glycerol to 1,3-propanediol (1,3-PDO) with high added value is attraction but challenging. Pt-WO_x-based catalysts have been extensively studied in the selective hydrogenolysis of glycerol. The catalyst support and the physicochemical state of WO_x play important roles on this reaction. In this paper, Pt-WO_x catalysts supported on TiO₂ with different crystal forms were prepared and studied for their catalytic performance in hydrogenolysis of glycerol. It was observed that the catalytic performance of anatase-type (A-type) TiO₂-supported catalyst (Pt/W/A-Ti) is much better than that of the rutile-type (R-type) TiO₂ catalyst (Pt/W/R-Ti) due to its higher stability. Furthermore, the influence of W
