Is hematene worth pursuing?

Nanowerk.com - 14 февраля, 2020 - 15:39
Hematite as a magnetic photocatalyst can support the production of oxygen in its magnetic ground state and thereby improve the efficiency of hydrogen production. When hematite is made thinner, another important improvement in the efficiency of the reaction could be accomplished by expectedly more efficient separation of charge carriers upon the absorption of light on the surface. Scientists now elucidate exactly how optical and magnetic properties of hematite change when decreased in thickness to the atomistic scale.

Machine learning models accelerate the search for critical electrocatalysts

Nanowerk.com - 13 февраля, 2020 - 09:05
Oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER) are among the core electrochemical processes in clean energy conversion and storage devices, such as metal-air batteries, water electrolyzers, and fuel cells. Single-atom catalysts have emerged as a new frontier of heterogeneous catalysts for these reactions due to their highly increased coverage of active sites, enhanced catalytic performance, and maximal metal utilization. By using machine learning algorithms, researchers provide a new paradigm for directly predicting the catalytic performance from physical properties of catalyst candidates.
