Effective electronic tuning of Pt single atoms <i>via</i> heterogeneous atomic coordination of (Co,Ni)(OH)<sub>2</sub> for efficient hydrogen evolution

نویسندگان

چکیده

A Pt 1 /(Co,Ni)(OH) 2 /C single-atom electro-catalyst efficiently splits water for H generation, via balanced water-dissociation and -formation steps from the synergistic effect of surface-defective (Co,Ni)(OH) electronically tuned sites.

Potential‐Cycling Synthesis of Single Platinum Atoms for Efficient Hydrogen Evolution in Neutral Media

Single-atom catalysts (SACs) have exhibited high activities for the hydrogen evolution reaction (HER) electrocatalysis in acidic or alkaline media, when they are used with binders on cathodes. However, to date, no SACs have been reported for the HER electrocatalysis in neutral media. We demonstrate a potential-cycling method to synthesize a catalyst comprising single Pt atoms on CoP-based nanot...

Effective atomic orbitals for fuzzy atoms.

The method of extracting effective atomic orbitals and effective minimal basis sets from molecular wave function characterizing the state of an atom in a molecule is developed in the framework of the "fuzzy" atoms. In all cases studied, there were as many effective orbitals that have considerable occupation numbers as orbitals in the classical minimal basis. That is considered to be of high con...

Restructuring and Hydrogen Evolution on Pt Nanoparticle.

The restructuring of nanoparticles at the in situ condition is a common but complex phenomenon in nanoscience. Here, we present the first systematic survey on the structure dynamics and its catalytic consequence for hydrogen evolution reaction (HER) on Pt nanoparticles, as represented by a magic number Pt44 octahedron (∼1 nm size). Using a first principles calculation based global structure sea...
