Conversion of bimetallic MOF to Ru-doped Cu electrocatalysts for efficient hydrogen evolution in alkaline media

Engineering Ruthenium-Based Electrocatalysts for Effective Hydrogen Evolution Reaction

“…Copper (Cu) has been applied in many catalytic systems due to its excellent electrical conductivity. Experimental and theoretical calculations have confirmed that the introduction of Cu in HER can regulate the electronic structure of Ru-based catalysts, thus the catalyst shows optimal H desorption capacity [ 48 ]. Cheng et al [ 49 ] reported a facile wet chemistry method for in situ growth of amorphous RuCu nanosheets on crystalline Cu nanotubes (3D RuCu NCs).…”

Metal–Organic Framework‐Based Electrocatalysts for CO2 Reduction

“…The recent developments in electrocatalysis coupling the MOF‐derived nanomaterials are incessantly growing for the application of energy‐related problems. [ 31,32,151–154 ] Consequently, these materials are also being developed for CO 2 RR, preceding the drawbacks of pristine MOFs, these are being synthesized from MOFs either via high‐temperature pyrolysis or electrochemical conversion. Categorized by MOFs’ inherited porosity and surface area with addition of enhanced stability and conductivity, MOF‐derived materials are being more attractive for catalytic applications including CO 2 RR.…”

Cu-Based Multicomponent Metallic Compound Materials as Electrocatalyst for Water Splitting

“…Among them, single-component metallic compound has also shown excellent behavior as an electrocatalyst for water splitting ( Jebaslinhepzybai et al, 2021 ). In particular, the introduction of the second metal ions can change the electronic state of the active metal, vacancy concentration ( Yuan et al, 2021 ), coordination environment, or electron band structure ( Zhang et al, 2017b ), therefore enhancing HER kinetics ( Yang and Chen, 2020 ; Li et al, 2021 ), such as the use of plasma treatment method to activate the Cu surface ( Lee et al, 2018 ; Tomboc et al, 2020 ), by doping additional elements or with other metal alloys to adjust the binding energy of the reaction intermediates ( Gatalo et al, 2019 ), and the Cu species into a specific structure or a specific crystal plane ( Koh and Strasser, 2007 ; Liu et al, 2021 ; Yan et al, 2021 ; Yang et al, 2021 ). Christoph R. Muller ( Kuznetsov et al, 2020 ) studied the surface oxygen vacancies (V O ) in Y 1.8 M 0.2 Ru 2 O 7−δ (M = Cu, Co, Ni, Fe, Y) by an increased concentration of V O sites correlating with a superior OER activity.…”
