Metal organic frameworks are thoroughly reviewed as exemplary precursors for the manufacture of highly catalytically active materials.
Electrochemical reduction of carbon dioxide (CO2 ) into chemicals and fuels has recently attracted much interest, but normally suffers from a high overpotential low selectivity. In this work, single P atoms were introduced N-doped supported Fe atom catalyst (Fe-SAC/NPC) mainly in the form P-C bonds for CO2 electroreduction to CO an aqueous solution. This exhibited Faradaic efficiency ≈97 % at 320 mV, Tafel slope only 59 mV dec-1 , comparable state-of-the-art gold catalysts. Experimental...
The exploitation of highly efficient carbon dioxide reduction (CO2 RR) electrocatalyst for methane (CH4 ) electrosynthesis has attracted great attention the intermittent renewable electricity storage but remains challenging. Here, N-heterocyclic carbene (NHC)-ligated copper single atom site (Cu SAS) embedded in metal-organic framework is reported (2Bn-Cu@UiO-67), which can achieve an outstanding Faradaic efficiency (FE) 81 % CO2 to CH4 at -1.5 V vs. RHE with a current density 420 mA cm-2 ....
Photoreduction of CO2 into solar fuels has received great interest, but suffers from low catalytic efficiency and poor selectivity. Herein, two single-Cu-atom catalysts with unique Cu configurations in phosphorus-doped carbon nitride (PCN), namely, Cu1 N3 @PCN P3 were fabricated via selective phosphidation, tested visible light-driven reduction by H2 O without sacrificial agents. was exclusively active for CO production a rate 49.8 μmolCO gcat-1 h-1 , outperforming most polymeric (C3 N4 )...
An Fe–N–C catalyst with an FeN4 active moiety has gained ever-increasing attention for the oxygen reduction reaction (ORR); however, catalytic performance is sluggish in acidic solutions and regulation still a challenge. Herein, Fe–Mo dual-metal sites were constructed to tune ORR activity of mononuclear Fe site embedded porous nitrogen-doped carbon. The cracking O–O bonds much more facile on atomic pair due preferred bridge-cis adsorption model molecules. downshift d band center when Mo atom...
Developing efficient and stable electrocatalysts within a wide potential range is vital for the mature applications of electrocatalytic CO2 reduction reaction (CO2RR) into value-added chemical products. Herein, we engineered NC@Ni/C nano-composite featuring core–shell structure pyridinic-N-rich carbon layer encapsulating Ni nanoparticles (NPs) as highly effective electrocatalyst CO2RR to CO over range.

Fischer–Tropsch synthesis (FTS) is a significant catalytic process for the production of liquid fuel and fine chemicals from natural gas-, coal-, biomass-derived syngas.
