Cocatalyst loaded Al-SrTiO cubes for Congo red dye photo-degradation under wide range of light.

The continued pollution, waste, and unequal distribution of the limited amount of fresh water on earth are pushing the world into water scarcity crisis. Consequently, development of revolutionary, cost-effective, and efficient techniques for water purification is essential. Herein, molten flux method was used for the preparation of micro-sized Al-doped SrTiO photocatalyst loaded with RhCrO and CoOOH cocatalysts via simple impregnation method for the photo-assisted degradation of Congo red dye under UV and visible irradiation compared with P25 standard photocatalyst.

Anodic nanoporous WO modified with BiS quantum dots as a photoanode for photoelectrochemical water splitting.

Although anodic nanoporous (ANP) WO has gained a lot of attention for photoelectrochemical water splitting (PEC-WS), there is still a lack of efficient WO-based photoanodes with sufficient light absorption and good e/h separation and transfer. The decoration of ANP WO with narrow bandgap semiconductor quantum dots (QDs) can enhance charge carrier transfer while reducing their recombination, resulting in a high PEC efficiency. In this study, ANP WO was synthesized via an anodic oxidation process and then modified with BiS QDs via successive ionic layer adsorption and reaction (SILAR) process and examined as a photoanode for PEC-WS under ultraviolet-visible illumination.
