In situ photodeposition of copper nanoparticles on TiO2: Novel catalysts with facile light-induced redox cycling

The in situ photodeposition method of copper(0) nanoparticles on TiO2 is found to produce photoactive heterogeneous catalysts suitable for redox reactions. Several variables in the method that affect catalyst structure and activity have been investigated for H2 generation as a model reaction. The counter-anion of the copper salt used plays a pivotal role in determining size, distribution and crystallinity of the nanoparticles, as well as...
