Water electrolysis is a promising technology for producing renewable hydrogen energy. However, achieving high-efficiency water electrolysis has been impeded by the sluggish kinetics of the electrocatalyst. Therefore, developing highly active and cost-effective electrocatalysts for high-efficiency water electrolysis is essential. In this study, cobalt-iron layered double hydroxide (LDH) was synthesized at different temperatures using a simple co-precipitation method. Single-phase CoFe-LDH was observed only at low synthesis temperatures (≤ 40 °C), and LDH and oxides existed as a mixture as the synthesis temperature increased. Further, as the synthesis temperature increased, the crystallinity and crystallite size of LDH accordingly increased. CoFe-LDH with a low crystallinity showed the best catalytic activity for the OER due to the rich crystallite boundary. This study expedites a simple and low-temperature synthesis technique of highly active OER electrocatalysts.
