Thein situphotodeposition method of copper(0) nanoparticles on TiO2is found to produce photoactive heterogeneous catalysts suitable for redox reactions. Several variables in the method that effect catalyst structure and activity have been investigated for H2generation as a model reaction. The counter-...

A new kind of ternary Pt(Cu)/TiO2 catalyst was prepared by photodeposition of Cu on TiO2 powder support and subsequent galvanic deposition of Pt from a solution of K2PtCl6 salt. For its characterization energy-dispersive spectrometry, transmission electron microscopy, X-ray photoelectron spectroscopy...
XRD, TEM, XPS-AES, H2-TPR and FTIR of CO adsorption were employed to characterize Cu/TiO2samples and the exact composition of Cu/TiO2prepared by photo-deposition was determined to be Cu–Cu2O/TiO2. Based on the catalytic and characterization results, the possible mechanism for CO oxidation ...
Formic acid was used to evaluate the photoactivity of the photodeposited materials. The results showed that the materials achieved a higher photoactivity than S-TiO2 under ultraviolet light and most of the materials, especially Cu/S-TiO2, achieved slightly higher activity under visible light. The ...

Ti/TiO2 electrodeElectrochemical detectionHeavy metal ionsHere we reported that UV light irradiation can significantly enhance sensitivity of Ti/TiO2 electrode for determination of trace heavy metal ions (such as Cu2+, Pb2+ and Cd2+) owing to the photodeposition of metal ions on the surface of ...
Ag and Cu metals due to their strong surface plasmons and visible light sensitivities have been incorporated with TiO2 for various solar applications. But the effect of mutual interaction between these two metals and role of photodeposition (PD) time has not been studied which may bring new ...
