Abstract Electrochemical reduction of carbon dioxide (CO 2 ) to fuels and value‐added industrial chemicals is a promising strategy for keeping healthy balance between energy supply net emissions. Here, the facile transformation residual Ni particle catalysts in nanotubes into thermally stable single atoms with possible NiN 3 moiety reported, surrounded porous N‐doped sheath through one‐step nanoconfined pyrolysis strategy. These structural changes are confirmed by X‐ray absorption fine...

Rapid deployment new energies makes renewable energy driven CO2 electroreduction to chemical feedstocks and carbon-neutral a feasible cost-effective pathway for achieving net-zero emission. With the urgency goal, we initiated our research on electrolysis with emphasis industrial relevance.The molecules are thermodynamically stable due high activation two C═O bonds, efficient...
Abstract Metal–organic frameworks (MOFs) are regarded as promising materials for CO 2 adsorption, which is an important step in electrochemical reduction. In this work, zeolitic imidazolate framework (ZIF‐8) nanomaterials were synthesized with various zinc sources and used electrocatalysts reduction to CO. Among them, ZIF‐8, prepared using ZnSO 4 , delivers the best catalytic activity towards electroreduction, 65 % yield. The main center can be attributed discrete Zn nodes ZIF‐8....
Single-atom Co catalyst Co-Tpy-C with well-defined sites is synthesized by pyrolysis of a terpyridine (Tpy) organometallic complex. The exhibits excellent activity for the electrochemical CO2 reduction reaction in aqueous electrolyte, CO faradaic efficiency (FE) over 95% from -0.7 to -1.0 V (vs RHE). By comparison, catalysts without or Tpy ligand added do not show any high FE. When simulated flue gas 15% used as source , FE kept at 90.1% -0.5 versus RHE. During phase flow electrolysis using...
Ni3N/MCNT (multiwalled carbon nanotube) nanocomposites fabricated by ammonolysis displayed high CO2 electrochemical reduction reactivity with CO Faradaic efficiencies of 89.0% and current density 6.5 mA cm–2 at −0.73 V vs reversible hydrogen electrode (RHE). The catalyst could operate under weakly acidic conditions in the pH range 2.5–7.2. Even 2.5, efficiency remained 50.1%, demonstrating selectivity for reduction. be due to increased adsorption on Ni3N surface, which can compete evolution...
