A stable bimetallic Au-Ag/TiO2 nanopaper for aerobic oxidation of benzyl alcohol

Well-dispersed small Au-Ag bimetallic nanoparticles (sub-3 nm) on one dimensional TiO2 nanobelts were synthesized by a facile successive photodeposition-galvanic replacement method. Based on these Au-Ag/TiO2-NB nanostructures, a porous paper-like monolithic catalyst was fabricated and exhibited synergistically enhanced activity and stability for catalyzing aerobic oxidation of benzyl alcohol.
