2019年4月22日 · Here, we report on the design and synthesis of highly active TiO 2 photocatalysts incorporating site-specific single copper atoms (Cu/TiO 2) that exhibit a reversible and cooperative ...

2020年6月15日 · Cu-TiO 2 has superior activity for photocatalytic oxidation of HCHO under visible light. The presence of H 2O greatly promote the activity for HCHO oxidation. CuO x clusters on TiO 2 have the super reversibility between Cu (II) and Cu (I). OH plays the crucial role in surface formate decomposition rather than the O 2−.

2023年7月15日 · Herein, combining the high activity of SAs with the bandgap regulation of doping, we proposed a metal surface doping strategy to construct Cu single-atoms TiO 2 (CuSAs-TiO 2).

2024年3月10日 · Extensive work on a Cu-modified TiO 2 photocatalyst for CO 2 reduction under visible light irradiation was conducted. The structure of the copper cocatalyst was established using UV–vis diffuse reflectance spectroscopy, high-resolution transmission electron microscopy, X-ray absorption spectroscopy, and X-ray photoelectron spectroscopy.

2006年9月11日 · In the present paper we try to improve the photocatalytic activity of TiO 2 by different Cu doping procedures. In this case, we have combined the structural and surface effect of different acids used in the preparation procedure, and the presence of Cu doping species.

1 天前 · Notably, the optimized sample (0.075 M Cu-doped TiO2) exhibited superior performance as a DSSC photoanode, surpassing both pristine TiO2 and other doped samples. When paired with anthocyanin dye and incorporating 0.075M Cu into TiO2 NPs, the maximum photocurrent density of the DSSC increased from 5.8 to 7.6 mA cm-2, leading to an improvement in ...
