制备了Pt/CeO 2-ZrO 2-Bi 2 O3/SBA-16催化剂，用于甘油高选择性氧化制二羟基丙酮。来自CeO 2-ZrO 2-Bi 2 O3促进剂的活性氧供应在中等条件下（即在30 ℃下没有施加压力）有效地氧化甘油以产生DHA。在Pt/CeO 2-ZrO 2-Bi 2 O3/SBA-16催化剂上反应4 h后，DHA的产率和选择性分别提高到76%和84%。
ABSTRACT A Pt/CeO2-ZrO2-Bi2O3/SBA-16 catalyst was prepared to realize highly selective oxidation of glycerol to produce dihydroxyacetone (DHA). An active oxygen supply from the CeO2-ZrO2-Bi2O3 promoter effectively oxidized glycerol to produce DHA under moderate conditions (i.e. at 30°C without applied pressure). After a 4 h catalytic reaction using the Pt/CeO2-ZrO2-Bi2O3/SBA-16 catalyst, the DHA yield and selectivity rose to 76% and 84%, respectively.
