Retracted article: Synthesis of Pt@TiO2@MnOx hollow spheres with high spatial charge separation efficiency for photocatalytic overall water splitting

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 and 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).
