Cu-based MOF-derivatived catalyst for efficient electrocatalytic reduction of nitrogen and nitrate to produce ammonia

Preparation of Ru-doped Cu-based catalysts for enhanced electrochemical ammonia synthesis from efficient electrocatalytic nitrate reduction

“…It had been demonstrated that the catalyst was involved in the reduction reaction with more power passing around the working electrode and faster electron gain and loss, so that the reaction would be more violent, and the reduction effect would be the best. 52 The subsequent experimental studies in this paper are based on it.…”

Recent Progress and Perspectives on Transition Metal-Based Electrocatalysts for Efficient Nitrate Reduction

“…MOF-derived materials, with strong interactions between their carbon carriers and metal nanoparticles, can effectively improve the electrocatalytic performance, enhancing the stability of the catalysts. Li et al 135 prepared Cu/Cu 2 O@C by encapsulating Cu nanoparticles and their oxides in a porous carbon skeleton, which significantly improved its electrochemical stability and durability, with an NH 3 yield of 158.66 μmol cm −2 h −1 and FE of 76.97% at −0.6 V vs RHE. In addition, MOF composites, such as zeolite imidazolate frameworks (ZIF), are highly efficient precursors for the preparation of nitrogen-doped carbon (M-N-C) catalysts with a three-dimensional carbon structure that is stable and abundant in the metal active sites.…”

Plasma-engraved Co3O4 nanorods with enriched oxygen vacancies for efficient electrocatalytic ammonia synthesis

“…Currently, a variety of metal oxides are widely utilized catalysts for the NO 3 RR, due to the ordered network features, abundant open metal sites, and tunable chemical structures and morphologies. 20–22 In the work by Li et al , 23 Cu/Cu 2 O exhibited an ammonia yield of up to 2.7 mg cm −2 h −1 and Faraday efficiency of 76.9% at −0.5 V vs. reversible hydrogen electrode (RHE). Xu et al 24 reported that Co 3 O 4 could achieve an NH 3 yield of 4.9 mg cm −2 h −1 while the Faraday efficiency was only 56.9% at −0.5 V vs. RHE.…”
