Herein, it is shown that by engineering defects on CexSi1−xO2−δ nanocomposites synthesized via flame spray pyrolysis, oxygen vacancies can be created with an increased density of trapped electrons, enhancing the formation of reactive oxygen species (ROSs) and hydroxyl radicals in an ozone‐filled environment. Spectroscopic analysis and density functional theory calculations indicate that two‐electron...
Excellent photoelectrochemical performance of bismuth vanadate in water splitting is achieved by coupling with graphene sheets. On page 5295, R. Amal, S. C. Smith, Y. H. Ng, and co‐workers, demonstrate the ability to achieve efficient interfacial charge transfer between bismuth vanadate and graphene sheets by modulating the exposure extent of {010}/{110} facets of bismuth vanadate. The overall photoactivity...
Efficient interfacial charge transfer is essential in graphene‐based semiconductors to realize their superior photoactivity. However, little is known about the factors (for example, semiconductor morphology) governing the charge interaction. Here, it is demonstrated that the electron transfer efficacy in reduced graphene oxide‐bismuth oxide (RGO/BiVO4) composite is improved as the relative exposure...
