Photocorrosion of WO₃ Photoanodes in Different Electrolytes [PDF]

ACS Physical Chemistry Au, 2021
Photocorrosion of an n-type semiconductor is anticipated to be unfavorable if its decomposition potential is situated below its valence band-edge position. Tungsten trioxide (WO3) is generally considered as a stable photoanode for different photoelectrochemical (PEC) applications.

Ultrathin Hematite Photoanode with Gradient Ti Doping [PDF]

Research, 2020
The poor photoelectrochemical (PEC) performance derived from insufficient charge separation in hematite photoanode crucially limits its application. Gradient doping with band bending in a large region is then considered as a promising strategy, facilitating the charge transfer ability due to the built-in electric field.

BiVO₄ Photoanodes Enhanced with Metal Phosphide Co‐Catalysts: Relevant Properties to Boost Photoanode Performance

Small, 2023
AbstractAchieving highly performant photoanodes for oxygen evolution is key to developing photoelectrochemical devices for solar water splitting. In this work, BiVO4 photoanodes are enhanced with a series of core–shell structured bimetallic nickel‐cobalt phosphides (MPs), and key insights into the role of co‐catalysts are provided.

Metal-free photoanodes for C–H functionalization

Nature Communications, 2023
AbstractOrganic semiconductors, such as carbon nitride, when employed as powders, show attractive photocatalytic properties, but their photoelectrochemical performance suffers from low charge transport capability, charge carrier recombination, and self-oxidation. High film-substrate affinity and well-designed heterojunction structures may address these

Controlled Porosity in Ferroelectric BaTiO₃ Photoanodes

ACS Applied Materials & Interfaces, 2022
The use of ferroelectric polarization to promote electron-hole separation has emerged as a promising strategy to improve photocatalytic activity. Although ferroelectric thin films with planar geometry have been largely studied, nanostructured and porous ferroelectric thin films have not been commonly used in photo-electrocatalysis.

Ultrafast Charge Carrier Dynamics in CuWO₄ Photoanodes [PDF]

The Journal of Physical Chemistry C, 2021
CuWO4 is a ternary metal oxide semiconductor with promising properties for photoelectrochemical (PEC) water splitting and solar light conversion, due to its quite low band gap (2.3 eV) and high stability in an alkaline environment. Aiming at understanding the origin of the relatively low PEC efficiency attained with CuWO4 photoanodes, we here ...

Atomically thin photoanode of InSe/graphene heterostructure [PDF]

Nature Communications, 2021
AbstractAchieving high-efficiency photoelectrochemical water splitting requires a better understanding of ion kinetics, e.g., diffusion, adsorption and reactions, near the photoelectrode’s surface. However, with macroscopic three-dimensional electrodes, it is often difficult to disentangle the contributions of surface effects to the total photocurrent ...
