Correction: Nickel clusters on TiO2(110): Thermal chemistry and photocatalytic hydrogen evolution of methanol (Catal. Sci. Technol. (2020) DOI: 10.1039/d0cy01465f)

Under the section titled ‘Photocatalysis on Ni-decorated titania and auger analysis’, the work carried out in ref. 72 is incorrectly described as “a recent operando XPS study on a bimetallic NiCu–TiO2 photocatalyst for H2 evolution unequivocally shows the metallic state of both co-catalyst metals”.72 This should instead read “a recent operando XAS (X-ray absorption spectroscopy) study on a bimetallic NiCu–TiO2 photocatalyst for H2 evolution unequivocally shows the metallic state of both co-catalyst metals”.72 The details of ref. 72 are shown below as ref. 1. The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
