Discovery of High-Entropy Oxide Electrocatalysts: From Thin-Film Material Libraries to Particles.

ABSTRACT: Discovery of new high-entropy electrocatalysts requires testing of hundreds to thousands of possible compositions, which can be addressed most efficiently by high-throughput experimentation on thin-film material libraries. Since the conditions for high-throughput measurements ("screening") differ from more standardized methods, it is frequently a concern whether the findings from screening can be transferred to the commonly used particulate catalysts. We demonstrate the successful transfer of results from thin-film material libraries to particles of Cantor alloy oxide (Co-Cr-Fe-Mn-Ni)₃O₄. The chemical compositions of the libraries, all single-phase spinels, cover a wide compositional range of (Cr_8.1-28.0Mn_11.6-28.4Fe_10.6-39.0Co_11.
