Au supported on graphene quantum dots/TiO2 as oxidation catalyst

Heterogeneous photocatalysis has an industrial importance besides academic interest in the aerobic oxidation of organic molecules. In this regard, TiO2 is a suitable candidate due to its low cost, non-toxicity, high photostability, and photocatalytic activity which benefits its industrial applications. In continues of our interest in developing the useful catalytic systems for oxidation of organic compounds,1-4 herein titania nanoparticles combined with graphene quantum dots and Au nanoparticles was employed as a heterogeneous catalyst in the oxidation reaction of some alcohols and alkylarenes. Easy recovery, sustainability, high surface area, and chemical stability of the new catalyst make it attractive for the catalytic goals.
