Photodeposition of Pd nanoparticles on TiO 2 utilizing a channel type quartz reactor

Flash‐photoreduction method to enhance hydrogen photogeneration on Pd@TiO2

“…The spectra of the two catalysts differ in the higher ν (CO) region, corresponding to linear CO species. The observed bands at 2,097 and 2,113 cm −1 are assigned to linear adsorbed CO on bigger and smaller Pd NPs, respectively . Two clear linear CO bands in FT‐IR spectra of the CPR catalyst show the presence of the big palladium particles that are the result of the growth of small ones.…”

“…In particular, metal‐doped TiO 2 demonstrated good performances in the photocatalytic water‐splitting reaction. The metal loading, metal particle size distribution, and structure are the most effective parameters . Numerous studies have shown that a high dispersion of metal NPs leads to a significantly enhanced photocatalytic efficiency due to less recombination chance, the lower barrier for interfacial charge transfer (electron tunneling effect) and higher surface area …”

LED-driven controlled deposition of Ni onto TiO2 for visible-light expanded conversion of carbon dioxide into C1–C2 alkanes

“…Recently, the photocatalytic nature of some semiconducting metal oxides has been leveraged to reduce metal ions to nanosized metal particles upon light irradiation [43,44]. This so-called photodeposition procedure is a liquid-phase reaction that uses light in the UV range to induce an exciton pair in the surface of TiO 2 [45], which is firstly trapped at surface oxygen atoms. The photogenerated holes at the Ti-OH sites act as active species for the oxidation of solvent molecules, e.g.…”
