A Step toward Economically Viable Solar Fuel Production

Kevin Sivula

Recently in Joule, Zhang, Li, and colleagues reported a new benchmark in photocatalytic overall water splitting. By optimizing the co-catalysts and redox mediator between the light absorbers in a two-step heterogeneous photosystem, the authors reached an a ...

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

Xile Hu, Matthew Thomas Mayer, Laurent Liardet, 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 ...

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 ...
