Exeter team develops low-cost photoelectrode for spontaneous water-splitting using sunlight

Green Car Congress

Researchers at the University of Exeter (UK) have developed a novel p-type LaFeO 3 photoelectrode using an inexpensive and scalable spray pyrolysis method. The nanostructured photoelectrode results in spontaneous hydrogen evolution from water without any external bias applied with a faradaic efficiency of 30% and excellent stability.

Berkeley Lab nanoscale imaging study yields key insights into photo-electrochemical water splitting

Green Car Congress

In the quest to realize artificial photosynthesis to convert sunlight, water, and carbon dioxide into fuel—just as plants do—researchers need to not only identify materials to efficiently perform photoelectrochemical water splitting, but also to understand why a certain material may or may not work. —Johanna Eichhorn.

University at Buffalo-led team reports viable Mn-based catalyst for PEM fuel cells

Green Car Congress

A University at Buffalo-led research team has developed an efficient platinum group metal (PGM)-free catalyst for the oxygen reduction reaction (ORR) in PEM fuel cells that consists of atomically dispersed nitrogen-coordinated single Mn sites on partially graphitic carbon (Mn-N-C). and Harbin Institute of Technology.

UBC team uses plasma pretreatment to improve water transport in fuel cell electrodes

Green Car Congress

Researchers at the University of British Columbia (UBC) have used a plasma pre-treatment to achieve through-plane wettability of carbon layers in a fuel cell electrode. For the proton exchange membrane fuel cells (PEMFCs), an optimal balance of water level is critical for high performance and durability. 2018.07.005.

Researchers split water by altering photosynthetic machinery in plants; semi-artificial photosynthesis

Green Car Congress

A new study, led by academics at St John’s College, University of Cambridge, has used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and manmade technologies. Katarzyna P.
