摘要

•Bimetallic PdPt NPs supported on TiO2 nanowires were synthetized by a facile method.•The control over the oxygen vacancies in the support led to highly active catalysts.•PdPt NPs enabled to adjust the concentration of oxygen vacancies in the TiO2 support.•A volcano plot between the activity and the composition of PdPt NPs was observed.
