Pt single-atom loaded on nonmetallic elements (C, N, P, S) doped ZrO2 in photocatalytic hydrogen evolution: First principles

open access: yesMaterials & Design, 2023
It is of great significance to regulate the coordination environment of ZrO2 to enhance its photocatalytic hydrogen evolution activity. In this paper, non-metallic elements (A = C, N, P, S) doped ZrO2 photocatalysts are designed based on first-principles,

Anti-dissolution Pt single site with Pt(OH)(O3)/Co(P) coordination for efficient alkaline water splitting electrolyzer

open access: yesNature Communications, 2022
Platinum is the most active catalyst for cathodic hydrogen evolution, however it is inefficient for anodic oxygen evolution. Here, authors examine Pt single sites in cobalt hydrogen phosphate as oxygen evolution catalysts in water splitting electrolyzers.
