Abstract

original image

Crystal clear: Dry plasma reduction is used for continuously immobilizing platinum nanoparticles on CVD-grown graphene under atmospheric pressure without using any toxic chemicals while keeping the temperature low. The PtNPs/graphene-coated counter electrode exhibits a reasonably low charge-transfer resistance and a high optical transmittance.
