Ionic Liquid‐Assisted Electrocatalytic NO Reduction to NH₃ by P‐Doped MoS₂

ChemCatChem, Год журнала: 2022, Номер 15(3)

Опубликована: Дек. 9, 2022

Abstract Ambient NH 3 electrosynthesis from NO reduction reaction (NORR) is attractive in replacing the industrial Haber‐Bosch route; however, competitive hydrogen evolution (HER) aqueous electrolyte typically induces a limited selectivity and activity toward production. Herein, hierarchical P‐doped MoS 2 nanospheres are developed as NORR electrocatalyst an ionic liquid (IL) for catalyzing of to with maximal Faradaic efficiency 69 % (−0.6 V vs RHE) peak yield rate 388.3 μg h −1 mg cat. (−0.7 RHE), both which comparable best‐reported results. Moreover, catalyst also shows stable over 30 6 cycles. Theoretical analyses further reveal that P dopants facilitate activation hydrogenation NO. Besides, employment hydrophobic IL slows down HER kinetics effectively.

Co Nanoparticles Confined in Mesoporous Mo/N Co‐Doped Polyhedral Carbon Frameworks towards High‐Efficiency Oxygen Reduction

Chemistry - A European Journal, Год журнала: 2023, Номер 29(23)

Опубликована: Янв. 11, 2023

Exploiting effective non-noble metal electrocatalysts for oxygen reduction reaction (ORR) is crucial fuel cells and metal-air batteries. Herein, we designed fabricated Co nanoparticles confined in Mo/N co-doped polyhedral carbon frameworks (Co-NP/MNCF) derived from polyoxometalate-encapsuled metal-organic framework, which showed comparable ORR performance with commercial Pt/C a larger diffusion-limited current density. Moreover, the Co-NP/MNCF also exhibited excellent stability methanol tolerance. These appealing performances can be attributed to porosity regulation heteroatom doping of framework frameworks, could beneficial exposure more active sites, optimization electronic structure mass transfer electrolyte/electron/ion.
