A novel TiO2 supported core–shell (Pd@Ag) bimetallic catalyst was fabricated via the sequential photodeposition method. The Ag shell effectively blocks high coordination sites on Pd core, and therefore pronouncedly enhances ethylene selectivity for catalytic hydrogenation of acetylene in excess ethylene.
