PtPd/C catalyst with hollow spherical sandwich structure was successfully prepared by electrostatic self-assembly one-step reductive route using sodium dodecyl sulfate as the capping and structure-directing agent in ethylene glycol solution by microwave-assisted process. It can prevent Pd metal from...
