Porous PdRh nanobowls: facile synthesis and activity for alkaline ethanol oxidation

A novel catalyst of porous PdRh nanobowls with open porosity has been developed by using urea as a guiding surfactant. Benefiting from the compositional and structural advantages, the newly developed PdPh NBs exhibits outstanding electrocatalytic activity for the EOR which might make them good anodic candidates for direct ethanol fuel cells.
