Phase Boundary Engineering of Co2P‐CoP Branched Nanoparticles Enhances Cobalt Oxidation for Oxygen Evolution Electrocatalysis

Advanced Materials, EarlyView.
Phase boundaries between Co2P and CoP are constructed through a controlled transformation of Co to Co2P‐CoP branched nanoparticles. The polycrystalline mixed‐phase Co2P‐CoP branches are enriched with phase boundaries that stabilize Co active sites for OER. This work highlights phase boundary engineering as a powerful approach to tailor active sites and

Electrocatalyst/Semiconductor Interfaces in Photoelectrocatalysts: Mechanistic Analysis of the Impact of Nanoparticle Electrocatalyst Coverage on Performance

Advanced Materials, EarlyView.
Reducing Ni nanoparticle coverage on n‐Si photoanodes enhances photovoltage by promoting thicker interfacial SiOx formation during photoelectrochemical oxygen evolution reaction (OER). Experiments, analytical modeling, and finite‐element simulations reveal that coverage‐dependent chemical interface evolution, rather than geometric effects alone ...
