Retraction for Journal of Materials Chemistry A: Synthesis of Pt@TiO2@MnOx hollow spheres with high spatial charge separation efficiency for photocatalytic overall water splitting

چکیده
We, the named authors, hereby wholly retract this Journal of Materials Chemistry A article due to the subsequent realisation that the O2 evolution rates reported an summarised in Fig. 5 cannot be repeated in the Valencia labs. However, the H2 evolution rates can still be reproduced. Because the oxidation products are mainly radicals or H2O2, we do not observe much O2 evolved. In addition, we also find that the O2 evolution rates seem to be related to the activity test equipment (the Hg lamp we used and the additives in H2O).

Efficient charge separation is a critical factor for solar energy conversion by heterogeneous photocatalysts. This paper describes the complete spatial separation of oxidation and reduction cocatalysts to enhance the efficacy of charge separation and surface reaction. Specifically, we design Pt@TiO2@MnOx hollow spheres (PTM-HSs) with Pt and MnOx loaded onto the inner and outer surface of TiO2 s...

متن کاملPlasmon-enhanced water splitting on TiO2-passivated GaP photocatalysts.
Integrating plasmon resonant nanostructures with photocatalytic semiconductors shows great promise for high efficiency photocatalytic water splitting. However, the electrochemical instability of most III-V semiconductors severely limits their applicability in photocatalysis. In this work, we passivate p-type GaP with a thin layer of n-type TiO2 using atomic layer deposition. The TiO2 passivatio...
متن کاملDesign and Synthesis of TiO2 Hollow Spheres with Spatially Separated Dual Cocatalysts for Efficient Photocatalytic Hydrogen Production
TiO₂ hollow spheres modified with spatially separated Ag species and RuO₂ cocatalysts have been prepared via an alkoxide hydrolysis-precipitation method and a facile impregnation method. High-resolution transmission electron microscopy studies indicate that Ag species and RuO₂ co-located on the inner and outer surface of TiO₂ hollow spheres, respectively. The resultant catalysts show significan...

Highly exposed facets TiO2 attracts enormous attention due to its excellent separation effect of photogenerated electron-hole pairs and induced high performance of photocatalytic activity. Herein, a novel hydrothermal etching reaction was used to synthesize graphene-wrapped TiO2 hollow core-shell structures. Different with the reported co-exposed facets TiO2 single crystal nanoparticles, the pr...
