Abstract
Effective and stable electrocatalysts for the oxygen evolution reaction (OER) are crucial for improving proton exchange membrane water electrolyzers. Herein we demonstrate that incorporating single iridium atoms into the spinel Co3O4 significantly enhances its OER stability and performance in acidic environments. This modification increases the lifespan of Co3O4 by 80 times and lowers overpotentials, surpassing the performance of the benchmark IrO2. Theoretical calculations reveal that the Ir atoms help strengthen the structure of Co3O4, enhance its ability to absorb hydroxide ions, and speed up the OER process, while preventing metal loss during the reaction.
期刊介绍：
The Chemical Engineering Journal is an international research journal that invites contributions of original and novel fundamental research. It aims to provide an international platform for presenting original fundamental research, interpretative reviews, and discussions on new developments in chemical engineering. The journal welcomes papers that describe novel theory and its practical application, as well as those that demonstrate the transfer of techniques from other disciplines. It also welcomes reports on carefully conducted experimental work that is soundly interpreted. The main focus of the journal is on original and rigorous research results that have broad significance. The Catalysis section within the Chemical Engineering Journal focuses specifically on Experimental and Theoretical studies in the fields of heterogeneous catalysis, molecular catalysis, and biocatalysis. These studies have industrial impact on various sectors such as chemicals, energy, materials, foods, healthcare, and environmental protection.
