Long-term electrocatalytic N₂ fixation by MOF-derived Y-stabilized ZrO₂: insight into the deactivation mechanism

Abstract

A MOF-derived carbon/Y-stabilized ZrO2 nanocomposite (C@YSZ) works as an efficient and long-term electrocatalyst for N2 fixation.

“…However, the U diss of Mn (−0.76 V) in MnMo@N6 is more negative than the limiting potential (−0.52 V), leading to the possible electrochemical instability. [ 37,65 ]…”

Recent advances in vacancy engineering of metal‐organic frameworks and their derivatives for electrocatalysis

“…203 For example, Luo and coworkers presented a MOF-derived carbon/Y stabilized ZrO 2 nanocomposite (C@YSZ) with oxygen vacancies for electrochemical NRR. 204 The obtained C@YSZ showed a large NH 3 yield of 24.6 mg/h/mg cat. and a high Faradaic efficiency (FE) of 8.2% at -0.5 V versus RHE.…”

“…In recent years, the oxygen vacancies have been proven as an active role for NRR, which can achieve the electron acceptance‐giving process, effectively capture metastable electron, and inject them into the antibonds of N 2 203 . For example, Luo and coworkers presented a MOF‐derived carbon/Y stabilized ZrO 2 nanocomposite (C@YSZ) with oxygen vacancies for electrochemical NRR 204 . The obtained C@YSZ showed a large NH 3 yield of 24.6 mg/h/mg cat.…”

“…[50] Furthermore, efficiency of ZrO 2 was improved to 8.20% by doping with Y. [51] The improved efficiency was ascribed to formation of stable oxygen vacancies generated by doping of Y. Table 2 shows the summary of catalytic properties of d 2 -transition elements toward NRR.…”
