Popis: (NH4)5H6PV8Mo4O40 is an improved bi-functional catalyst that has been used for oxidizing starch by hydrogen peroxide. The effects of oxidation with hydrogen peroxide on the carboxyl content were studied systematically to produce high polyhydroxycarboxylic acids even when using very low amounts of the catalyst. (NH4)5H6PV8Mo4O40 exhibited the best catalytic performance with a carboxylic content of 0.648 mol per 100 g, which could be attributed to the synergy of its Bronsted acidity and strong efficient oxidant center. This catalyst can perform controllable starch oxidation and can be recycled for reuse.
