A simple and facile method is developed for one-pot preparation of hierarchical dendritic PtPd nanogarlands supported on reduced graphene oxide (PtPd/RGO) at room temperature, without using any seed, organic solvent, or complex apparatus. It is found that octylphenoxypolyethoxyethanol (NP-40) as a soft template and its amount are critical to the formation of PtPd garlands. The as-prepared nanocomposites are further applied to methanol and ethanol oxidation with significantly enhanced electrocatalytic activity and better stability in alkaline media.
Porous Pt–Pd nanodendrites were fabricated by a co-chemical reduction method using both PVP and urea as the co-stabilizing and co-structure-directing agents. The Pt–Pd nanodendrites displayed high catalytic activity and stability toward the electrooxidation of methanol and ethylene glycol in alkaline media.
Popcorn-like PtAu nanoparticles were fabricated and further supported on rGO by ultrasonication. The as-prepared nanocomposites showed an enhanced electrocatalytic performance for ORR and methanol oxidation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
