Photocatalytic hydrogen evolution on a high-entropy oxide

The definition of high-entropy oxide is debated. In oxide literature, the term is commonly used to refer to any oxide with at least five principal cations. However, it has been suggested that this is a misnomer, as most reports neglect to calculate configurational entropy. Additionally, a survey of 10 HEOs found that only 3 were entropy-stabilized. It has been suggested that the term HEO be replaced with three terms: compositionally complex oxide, high-entropy oxide, and entropy-stabi… WebHigh entropy oxides (HEOs) are single phase solid solutions consisting of five or more elements in equiatomic or near-equiatomic proportions incorporated into the cationic sub … Web20 de abr. de 2024 · A high entropy oxide (Mg 0.2 Co 0.2 Ni 0.2 Cu 0.2 Zn 0.2 O) with superior lithium storage performance.
