Hollow and porous palladium nanocrystals: synthesis and electrocatalytic application

Abstract

This work proposes an effective and facile synthesis strategy for the direct preparation of high-quality Pd nanostructures with well-defined morphologies, such as porous nanobowls, nanocages, and solid nanoparticles. Hollow-structured mesoporous nanostructures endow Pd nanobowls with the best catalytic performance towards the methanol oxidation reaction, demonstrating that the porous Pd nanobowls are indeed promising electrocatalysts for practical application.
