Ni–Co Codoped RuO₂ with Outstanding Oxygen Evolution Reaction Performance

ACS Applied Energy Materials (2019)

Yiyi Wu Muhammad Tariq Waqas Qamar Zaman Wei Sun Zhenhua Zhou

Synthesizing oxygen evolution reaction (OER) catalysts with high activity by codoping has been proven to be feasible for effectively using noble metals via renewing their basic properties. Here, we prepare two series of Ru based codoped catalysts NixCoyRu1–x–yO2 with outstanding OER activity compared with RuO2, one of the state-of-the-art OER catalysts. The molar ratio of case dopants, nickel and cobalt, is regulated from 1:1 to 1:1.5 for the host structure RuO2 as the main variable. The synthesized codoped RuO2 with Co/Ni of 1.5 reflected a Tafel slope of only 32 mV dec–1, which is appreciably lower than the 64 mV dec–1 for pure RuO2. The performed X-ray photoelectron spectroscopy (XPS) indicated that the key factor of OER activity for codoped catalysts with different dopant ratio is the oxygen vacancy.

Toward efficient electrocatalytic oxygen evolution with a low concentration baking soda activated IrO_xsurface in a hydrothermal medium

The presence of HCO 3 − in a hydrothermal medium enables amorphous IrO x nanoparticles to possess a pseudo-crystalline morphology and further modifies the t 2g orbitals, thus substantially increasing the OER catalytic activity.

Achieving Active and Stable Amorphous Ir^VO_xOH_y for Water Splitting

ACS Applied Materials & Interfaces (2022)

Chenglong Ma Xuerui Yang Zhiqiang Wang Wei Sun Lin Zhu

Evaluating the structural and electronic-state characteristics of long-range disordered amorphous iridium (Ir)-based oxides is still unsatisfying. Compared with the benchmark IrO2, the higher oxygen evolution reaction (OER) performance brought by IrOxOHy was normally considered to be associated with the pristine IrIII-containing species. However, such a conclusion conflicts with the opinion that high-valence metals can create excellent OER activity. To resolve such contradictions, we synthesized a pure amorphous Lu1.25IrOxOHy (Lu = lutetium) catalyst in this work. In combination with the comprehensive electrochemical evaluation in alkaline and acidic media, ex situ Ir L3-edge and O K-edge X-ray absorption spectroscopy and theoretical calculations revealed that the ultrahigh OER performance of reconstructed IrOx/Lu1.25IrOxOHy in acidic media was identified to be driven by the more d-hole-containing electronic state of IrV created by cationic vacancies. The pristine properties of IrIII-containing Lu1.25IrOxOHy conversely inhibit the OER activity in alkaline media. Additionally, the high edge-shared [IrOx]-[IrOx] motif proportion structure in amorphous Lu1.25IrOxOHy achieves a stable OER process, which exhibits a high S-number stability index similar to IrO2. We demonstrate that the key factor of the edge-shared [IrOx]-[IrOx] motif with cationic vacancies in IrVOxOHy could rationally reveal the source for most of the high-performance Ir-based materials.
