Rationality in the new oxygen evolution catalyst development

Anodic oxygen evolution has gained significant prominence in electrochemical research in the last decade in connection with 
renewable electricity storage. With water being the only available fossil free source of hydrogen, which is deemed the 
primary storage medium, the water electrolysis optimization is one of the biggest challenges of today’s electrochemistry. A 
development of novel oxygen evolution reaction (OER) catalysts is motivated to increase the feasibility of the current 
OER catalysts in terms of activity, stability and price. This paper summarizes the most recent synthetic approaches in 
OER catalyst synthesis for acid and alkaline electrolyzers stressing the structural aspects of the proposed catalysts.
