Pd0@Polyoxometalate Nanostructures as Green Electrocatalysts: Illustrative Example of Hydrogen Production

Green-chemistry type procedures were used to synthesize Pd nanostructures encapsulated by a vanadium-substituted Wells-Dawson-type polyoxometalate (Pd@POM). The cyclic voltammogram run with the Pd@POM-modified glassy carbon electrode shows well-defined waves, associated with Pd nanostructures and the V/V redox couple. The Pd@POM-modified electrode displayed remarkably reproducible cyclic voltam...

Noncovalent immobilization of electrocatalysts on carbon electrodes for fuel production.

We show that molecular catalysts for fuel-forming reactions can be immobilized on graphitic carbon electrode surfaces via noncovalent interactions. A pyrene-appended bipyridine ligand (P) serves as the linker between each complex and the surface. Immobilization of a rhodium proton-reduction catalyst, [Cp*Rh(P)Cl]Cl (1), and a rhenium CO2-reduction catalyst, Re(P)(CO)3Cl (2), afford electrocatal...

New Electrocatalysts for Fuel Cells

Approach • Study the kinetics of fuel cell electrode reactions on well-characterized model electrodes and high surface area fuel cell electrocatalysts using modern electroanalytical methods. • Study the mechanisms of the reactions using state-of-the art in-situ spectroscopes. • Use ultrahigh vacuum (UHV) methods of surface preparation and surface analyses to form tailored surfaces. • Synthesize...

Hollow TiO2@Co9S8 Core–Branch Arrays as Bifunctional Electrocatalysts for Efficient Oxygen/Hydrogen Production

Designing ever more efficient and cost-effective bifunctional electrocatalysts for oxygen/hydrogen evolution reactions (OER/HER) is greatly vital and challenging. Here, a new type of binder-free hollow TiO2@Co9S8 core-branch arrays is developed as highly active OER and HER electrocatalysts for stable overall water splitting. Hollow core-branch arrays of TiO2@Co9S8 are readily realized by the ra...
