Abstract
High-entropy oxides (HEOs) exhibit high catalytic activities in the O2 evolution reaction (OER). Nevertheless, the methods used for the fabrication of these oxides necessitate the application of heat and/or pressure. Accordingly, herein, HEO colloids are produced by a facile procedure under ambient temperature and pressure conditions using a strong base, an oxidant, and metal salt(s). Using the proposed method, HEO colloids containing up to 12 metal elements are prepared and specifically tailored as electrocatalysts for the OER. This chemical approach enables the cost-effective production of HEO colloids with diverse compositions, opening the door to a wide range of applications of HEOs.
期刊介绍:
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
