Stainless steel made to rust: a robust water-splitting catalyst with benchmark characteristics [PDF]

, 2015
The oxygen evolution reaction (OER) is known as the efficiency-limiting step for the electrochemical cleavage of water mainly due to the large overpotentials commonly used materials on the anode side cause.

Switching on electrocatalytic activity in solid oxide cells [PDF]

Nature, 2016
Solid oxide cells (SOCs) can operate with high efficiency in two ways-as fuel cells, oxidizing a fuel to produce electricity, and as electrolysis cells, electrolysing water to produce hydrogen and oxygen gases. Ideally, SOCs should perform well, be durable and be inexpensive, but there are often competitive tensions, meaning that, for example ...
