A one-step room temperature photo-assisted synthesis has been implemented in liquid phase and under solar light for preparing highly dispersed TiO2 supported metallic Ru catalysts, with no need of final thermal treatment, external hydrogen, or chemical reductant. Whether RuCl3 chloride or Ru(acac)3 acetylacetonate precursor salt was used, sub-nanometric metallic Ru nanoparticles were synthesized on
