Covalent triazine frameworks, which are crosslinked porous polymers with two-dimensional molecular structures, are promising materials for heterogeneous catalysts. However, the application of the frameworks as electrocatalysts has not been achieved to date because of their poor electrical conductivity. Here we report that platinum-modified covalent triazine frameworks hybridized with conductive...

We report the first direct measurement of CO diffusion on nanoparticle Pt electrocatalysts at the solid/liquid interface, carried out using 13C nuclear magnetic resonance (NMR) with a spin-labeling pulse sequence. Diffusion parameters were measured in the temperature range of 253-293 K for CO adsorbed on commercial Pt-black under saturation coverage. 2H NMR of the same system indicates that the...

Developing low-cost and highly active electrocatalysts to replace Pt group metals is very critical the hydrogen evolution reaction (HER). Transition-metal carbides (TMCs) have drawn broad attention as potential HER catalysts in recent years due platinum-like electron structure. This review highlights strides on synthesis routes optimization strategies of TMC electrocatalysts, discusses future p...

Platinum and platinum-based catalysts are some of the most effective used in fuel cells. However, electrocatalysts for direct liquid cells (DLFCs) electrolyzers high cost suffer from several other problems, thus hindering their commercialization as power sources to produce clean energy. Common issues low stability durability, slow kinetics, catalyst poisoning, loading, catalytic materials, pois...

Performance of low temperature fuel cells depends critically on the nanostructures of the material components in the electrodes and membranes. Some studies are reported here for 1) mixed metal nanoparticles supported on mesoporous carbon and 2) modification of nanopores of Nafion via in-situ polymerization of furfuryl alcohol. The anodic oxidation of small organic molecules such as alcohols in ...

The oxygen reduction reaction (ORR) is a key energy conversion process, which critical for the efficient operation of fuel cells and metal–air batteries. Here, we report significant enhancement ORR-performance commercial platinum-on-carbon electrocatalysts when operated in aqueous electrolyte solutions (pH 5.6), containing polyoxoanion [Fe28(μ3-O)8(L-(−)-tart)16(CH3COO)24]20−. Mechanistic studi...
