Optimizing Pt-Based Alloy Electrocatalysts for Improved Hydrogen Evolution Performance in Alkaline Electrolytes: A Comprehensive Review.

ACS Nano, 2023
The splitting of water through electrocatalysis offers a sustainable method for the production of hydrogen. In alkaline electrolytes, the lack of protons forces water dissociation to occur before the hydrogen evolution reaction (HER).

Polarizability of atomic Pt, Pt+, and Pt−

The Journal of Chemical Physics, 2021
Electrostatic properties are important for understanding and modeling many phenomena, such as the adsorption of a catalytic metal upon an oxide support. The charge transfer between the metal and the support can lead to positive or negative charges on the metal.

Pt Single Atoms Supported on N‐Doped Mesoporous Hollow Carbon Spheres with Enhanced Electrocatalytic H2‐Evolution Activity

Advances in Materials, 2021
The electronic metal–support interaction (EMSI) plays a crucial role in catalysis as it can induce electron transfer between metal and support, modulate the electronic state of the supported metal, and optimize the reduction of intermediate species.

Pt···Pt vs Pt···S Contacts Between Pt-Containing Heterobimetallic Lantern Complexes

Inorganic Chemistry, 2013
A trio of Pt-based heterobimetallic lantern complexes of the form [(py)PtM(SAc)4(py)] (M = Co, 1; Ni, 2; Zn, 3) with unusual octahedral coordination of Pt(II) was prepared from a reaction of [PtM(SAc)4] with excess pyridine. These dipyridine lantern complexes could be converted to monopyridine derivatives with gentle heat to give the series [PtM(SAc)4 ...

Reversed Charge Transfer and Enhanced Hydrogen Spillover in Pt Nanoclusters Anchored on Titanium Oxide with Rich Oxygen Vacancies Boost Hydrogen Evolution Reaction.

Angewandte Chemie, 2021
The catalytic activity of metal clusters is closely related with the support, while the knowledge about the influence of support on the catalytic activity is scarce.

Energetics of Pt adsorption on Pt(111)

Physical Review B, 1994
First-principles local-density-functional (FP-LDF) and embedded-atom-method (EAM) total energies, for a single Pt atom adsorbed on Pt(111), are compared to each other and to field-ion-microscope (FIM) observations. Our EAM calculations predict a small barrier to diffusion and only a slight energy difference between adsorption in the fcc and hcp ...
