Synthesis and Enhanced Electrocatalytic Activity of Platinum and Palladium-Based Nanoflowers Supported on Reduced Graphene Oxide

Graphene-supported flower-shaped platinum and palladium nanomaterials assisted by hexadecyltrimethylammonium bromide have been successfully developed. Compared with the catalyst reduced by the redox reaction between metal precursors and graphene oxide, the flower-shaped catalyst obtained using reduction in active hydrogen atoms exhibits enhanced catalytic activity in alcohol electrocatalytic oxidation reactions. Repeated cyclic voltammetry and chronoamperometry tests both indicate that the prepared catalyst has excellent stability.

Ultralong PtNi alloy nanowires enabled by the coordination effect with superior ORR durability

Ultralong PtNi nanowires were prepared by taking advantage of the coordination effect to delicately control the reduction and alloying kinetics.

Self-assembly of platinum nanoparticles and coordination-driven assembly with porphyrin

The easily accessible surfaces of Pt nanostructures were demonstrated by two kinds of assembly processes.
