A novel combined seed mediated and galvanic replacement method has been demonstrated to synthesize a newclass of trimetallicPtAuAgnanocatalysts with highly open bowl-like nanocage structure. The newly-generatedPtAuAgnanocages catalysts exhibit superior electrocatalytic performances towards ethylene glycol oxidationwith the mass activity of 6357.1 mA mg^-1, 5.5 times higher than that of commercial Pt/C (1151.1 mA mg^-1).This work demonstrates the first example of designing shape-controlled architectures of trimetallic bowl-likePtAuAgnanocages for liquid fuel electrooxidation.
