Stabilizing Electrochemical Interfaces With Multifunctional Cobalt Nitride Layers

Advanced Materials Interfaces, EarlyView.
Cobalt nitrides emerged recently as an interesting class of earth‐abundant oxygen evolution catalysts. Herein, plasma‐enhanced atomic layer deposition is used to synthesize multifunctional cobalt nitride layers that simultaneously protect and catalytically activate photoelectrode surfaces.

Kinetics of Photoelectrochemical Oxidation of Methanol on Hematite Photoanodes [PDF]

Journal of the American Chemical Society, 2017
The kinetics of photoelectrochemical (PEC) oxidation of methanol, as a model organic substrate, on α-Fe2O3 photoanodes are studied using photoinduced absorption spectroscopy and transient photocurrent measurements. Methanol is oxidized on α-Fe2O3 to formaldehyde with near unity Faradaic efficiency.

Interpretation of Mott–Schottky plots of photoanodes for water splitting

Chemical Science, 2022
Electron injection from the contact dominates the Mott–Schottky plots of thin-film photoanodes, rather than the depletion capacitance.

Gas‐Selective Remote Plasma Engineering of WO3 Photoanodes for Solar Water Splitting

Advanced Materials Interfaces, EarlyView.
Gas‐selective remote plasma treatment tunes the near‐surface defect chemistry of WO3 photoanodes without altering their bulk structure. Ar plasma generates the most oxygen‐vacancy‐rich surface and the highest W5+ content, delivering the strongest photocurrent.

Photoelectrochemical studies of InGaN/GaN MQW photoanodes [PDF]

Nanotechnology, 2017
The research interest in photoelectrochemical (PEC) water splitting is ever growing due to its potential to contribute towards clean and portable energy. However, the lack of low energy band gap materials with high photocorrosion resistance is the primary setback inhibiting this technology from commercialisation.
