• production rate was found to increase to 1539.77 μmol/g/h. Thus, the ZnO quantum dots obviously prompted separation of charge carriers, which was explained by a proposed mechanism for this photocatalytic reaction.

• materials was evaluated by formation rate of methanol under UV light irradiation at ambient temperature and pressure. The methanol formation rate of pure KNb3O8 nanosheets was found to be 1257.21 μmol/g/h, and after deposition of 2 wt % ZnO quantum dots on the surface of KNb3O8 nanosheets, the methanol

• , cigarettes, proton-exchange membrane fuel cells, air purifiers, methanol production and water-gas shift reaction [1][2][3][4]. The catalytic oxidation of CO was revolutionized by Haruta et al. [5]. They worked on supported nanogold catalysts and found them to be highly active for CO oxidation. Till date
