Water Oxidation Kinetics of Accumulated Holes on the Surface of a TiO2 Photoanode: A Rate Law Analysis

Florian Le Formal, Yimeng Ma, Min Ling

It has been more than 40 years since Fujishima and Honda demonstrated water splitting using TiO2, yet there is still no clear mechanism by which surface holes on TiO2 oxidize water. In this paper, we use a range of complementary techniques to study this re ...

Photoelectrochemical deposition of CoP on cuprous oxide photocathodes for solar hydrogen production

Xile Hu, Laurent Liardet, Matthew Thomas Mayer, Lucas-Alexandre Stern, Carlos Gilberto Morales Guio

Photoelectrochemical (PEC) water splitting is an attractive and sustainable energy conversion method. In this work, cobalt phosphide (CoP) is photoelectrochemically deposited on a p-type cuprous oxide (pCu(2)O) photocathode for solar hydrogen production. U ...

Techno-economic modeling and optimization of solar-driven high-temperature electrolysis systems

Sophia Haussener, Meng Lin

We present a techno-economic analysis of solar-driven hightemperature electrolysis systems used for the production of hydrogen and synthesis gas. We consider different strategies for the incorporation of solar energy, distinguished by the use of differing ...

A Pd-Cu2O nanocomposite as an effective synergistic catalyst for selective semi-hydrogenation of the terminal alkynes only

Shuliang Yang, Li Peng

A new type lead-free catalyst of a Pd-Cu2O nanocomposite was developed for highly selective semi-hydrogenation of alkynes. With unprecedented selectivity for the semi-hydrogenation of terminal alkynes to alkenes, we show for the first time that the catalys ...

Modeling, Simulation, and Implementation of Solar-Driven Water-Splitting Devices

Sophia Haussener, Miguel Antonio Modestino, Rui Liu, Ke Sun

An integrated cell for the solar-driven splitting of water consists of multiple functional components and couples various photoelectrochemical (PEC) processes at different length and time scales. The overall solar-to-hydrogen (STH) conversion efficiency of ...

Modeling of concurrent CO2 and water splitting by practical photoelectrochemical devices

Sophia Haussener, Ronald Ramiro Gutierrez Perez

Concurrent solar generation of hydrogen and CO through photoelectrochemical (PEC) water and CO2 electrolysis, and the subsequent use of the product gas mixture in conventional Fischer-Tropsch processes, has the potential to provide a flexible pathway for d ...

Photoinduced Absorption Spectroscopy of CoPi on BiVO4: The Function of CoPi during Water Oxidation

Florian Le Formal, Yimeng Ma

This paper employs photoinduced absorption and electrochemical techniques to analyze the charge carrier dynamics that drive photoelectrochemical water oxidation on bismuth vanadate (BiVO4), both with and without cobalt phosphate (CoPi) co-catalyst. These r ...
