WebIrOOH nanosheets as acid stable electrocatalysts for the oxygen evolution reaction. Daniel Weber, Leslie M. Schoop, Daniel Wurmbrand, Sourav Laha, Filip Podjaski, Viola Duppel, … WebThree typical peaks of O 1s appear at 530.30 eV, 531.69 eV, and 532.83 eV for lattice Ir-O2-, Ir-OH, and adsorbed water, respectively. And it is estimated that Ir-O2-and Ir-OH give a ratio of 7.9. Synthesized nanosheets give an Ir:O atom ratio of 1:2.4, after stability measurement, it comes to 1:5.25. S-17 Figure S16.

WebThe discovery of a new valence state in ternary crystalline iridium oxides is not only of interest from a fundamental perspective, but also has far-reaching implications for such diverse fields as electrochromism, solid-state magnetism, and especially heterogeneous catalysis. All Science Journal Classification (ASJC) codes Chemistry (all) WebThey outperform bulk rutile-IrO 2 and bulk IrOOH as electrocatalytic water oxidation catalysts under the same conditions. The results of this study on the structure-property relationships of low valence IrOOH nanosheets offer new pathways for the development of atom efficient, robust and highly active oxygen evolution catalysts. ... css margin top失效
