In this work, the effects of addition transition metals (Mn, Fe, Co, Ni, Cu) on structure and performance doped carbon catalysts M-PANI/C-Mela are investigated. The results show that doping various affected structures performances significantly. Doping with Fe Mn leads to a catalyst graphene-like structure, Cu disordered or nanosheet structure. can enhance catalysts, their ORR activity follows order > Co which is consistent active N contents. We suggest enhancements may be result joint...
The main challenges to the commercial viability of polymer electrolyte membrane fuel cells are (i) high cost associated with using large amounts Pt in cell cathodes compensate for sluggish kinetics oxygen reduction reaction, (ii) catalyst degradation, and (iii) carbon-support corrosion. To address these obstacles, our group has focused on robust, carbon-free transition metal nitride materials low content that exhibit tunable physical catalytic properties. Here, we report performance a novel...
Abstract All‐solid‐state (ASS) lithium metal batteries (LMBs) are considered the most promising next‐generation due to their superior safety and high projected energy density. To access practically desired density of ASS LMBs, an ultrathin solid‐state electrolyte (SSE) film with fast ion‐transport capability presents as irreplaceable component reduce proportion inactive materials in batteries. In this contribution, (60 µ m), flexible, free‐standing argyrodite (Li 6 PS 5 Cl) SSE is designed...

A class of core–shell structured low-platinum catalysts with well-dispersed inexpensive titanium copper nitride nanoparticles as cores and atomic platinum layers shells exhibiting high activity stability for the oxygen reduction reaction is successfully developed. Using nitrided carbon nanotubes (NCNTs) support greatly improved morphology dispersion nanoparticles, resulting in significant enhancement performance catalyst. The optimized catalyst, Ti0.9Cu0.1N@Pt/NCNTs, has a Pt mass 5 times...

Abstract All‐solid‐state lithium‐sulfur batteries are strongly considered as the most promising next‐generation electrochemical energy storage systems due to their high safety and density. However, in view of practical application, it is difficult obtain large‐scale solid‐state sulfur cathode continuously. Herein we achieve fabrication solid by a facile slurry‐coating process through screening various solvents binder contents. The composite cathodes all‐solid‐state pouch cells exhibit...

Poor durability is one of the two major problems hindering commercialization proton exchange membrane fuel cells, due to Pt nanoparticle aggregation in electrocatalyst and corrosion its carbon support. In this paper, we report a which black decorated with tin silicon binary oxide layer was used as support, SnO2 promoter SiO2 stabilizer. Transmission electron microscopy revealed that formed thin on surface support particles. The catalyst exhibited significantly enhanced performance toward...

We synthesize a platinum monolayer core‐shell catalyst with ternary alloy nanoparticle core of Pd, Ir, and Ni. A Pt is deposited on carbon‐supported PdIrNi nanoparticles using an underpotential deposition method, in which copper applied to the nanoparticles; this followed by galvanic displacement Cu generate surface core.
