Abstract

Abstract

En 中文
• Hydrogen titanate nanotubes were modified with graphene oxide and Au nanoparticles. • Addition of GO and Au significantly enhanced the adsorption of methylene blue dye. • Prepared xAu/NTGO2 catalysts showed better photocatalytic activity compared to P25. • PL confirmed a low rate of recombination of e-/h+ pairs in xAu/NTGO2 catalysts. • xAu/NTGO2 catalysts are promising for MB degradation under natural solar light.
