WebNov 5, 2024 · 1. Introduction. The two-dimensional structure of CoOOH has been widely used as oxygen evolution reaction (OER) catalysts due to easy preparation, low cost, and good electrical conductivity [1], [2], [3].Although the CoOOH nanosheet has been used as common OER catalysts, there are still some obvious shortcomings [4], [5], [6].Compared … WebHere, we present an atomically thin cobalt oxyhydroxide (γ-CoOOH) nanosheet as an efficient electrocatalyst for water oxidation. The 1.4 nm thick γ-CoOOH nanosheet electrocatalyst can effectively oxidize water with extraordinarily large mass activities of 66.6 A g −1 , 20 times higher than that of γ-CoOOH bulk and 2.4 times higher than ... hcg diet safe while breastfeeding
