Photodeposition method In the PD method Ag metal doped on TiO 2 was prepared by photoreducing Ag + ions to Ag metal on the TiO 2 surface according to the following steps. First, 3.0 g of TiO 2 was added to 100 ml deionized water. The pH of the TiO 2 suspension was adjusted to 3 by addition of perchloric acid. Then the required amount of AgNO

Photodeposition was conducted within a Pyrex topped reaction cell. In a typical process, 1 g of TiO2 powder (P25, Degussa) was suspended in 120 ml water at 25 °C. An appropriate amount of chloroplatinic acid (H2PtCl6, Sinoreagent) was added, mixed under ultrasonication and subsequent stirring for 30 min, … See more Energy security and climate change represent key global challenges arising from historic reliance on fossil fuels.1–3 Artificial photosynthesis offers the possibility of clean … See more Methanol plays a critical role in controlling platinum PD over titania through promoting the formation of highly dispersed metallic Pt nanoparticles at the titania interface via increasing the density of surface electrons … See more The photocatalytic activity of the PD samples over 1 wt% Pt/TiO2 (P25) is shown in Fig. 1 as a function of methanol concentration employed during the PD synthesis. H2 … See more This work was supported by the financial support from Shanghai Natural Science Foundation (14ZR1421900), National Science Foundation of … See more WebPhotodeposition of H 2 PtCl 6 in the presence of methanol promotes the formation of highly dispersed, metallic Pt nanoparticles over titania, likely via capture of photogenerated holes by the alcohol to produce an excess of surface electrons for substrate-mediated transfer to Pt complexes, resulting in a high density of surface nucleation sites for Pt reduction. ds byproduct\u0027s
