Unveiling the bifunctional role of morphological differences of self-supported Cu(OH)2 in electrocatalysis

Abstract

In this article, Cu(OH)2 with various morphology has been synthesized within 200 s by employing an anodization technique. The formation of Cu(OH)2 was confirmed using XPS, XANES and EXAFS techniques. Copper ions in Cu(OH)2 possess good charge transfer abilities that are capable of evolving oxygen molecules more potent than CuO. Unlike CuO, Cu(OH)2 gets oxidised easily and thus can give good stability for up to 72 h. The prepared catalyst exhibited bifunctional activity with an overpotential of 400 mV at 10 mA cm−2 for the OER and 315 mV for the MOR, respectively.
