Fe doping promoted electrocatalytic N2 reduction reaction of 2H MoS2

Recent advances in MoS2-based materials for electrocatalysis

“…7a) revealed that the enhanced NRR activity was independent of the location of doped Fe. 173 Interestingly, MoS 2 with bimetal-doping (Ni and Fe) was reported as a new promising NRR catalyst, exhibiting trimetallic synergistic interactions and thus great NRR performances (an NH 3 yield rate of 128.17 μg h −1 mg −1 cat. and FE of 11.43%) in Chen's work.…”

MoS2‐Based Catalysts for N2 Electroreduction to NH3 – An Overview of MoS2 Optimization Strategies

“…Most of the current MoS 2 synthesis processes involve ammonium ions, which leads to unclear N sources in the NRR process. Partially replacing S atoms in 2H-MoS 2 with Fe atoms (Figure 4C), Guo et al used an ammonium-free hydrothermal process to grow Fe@2H-MoS 2 on carbon cloth, [67] thus successfully avoiding the problem of unclear N sources. The substituted Fe atoms affected the electronic state of Mo and S atoms, which facilitated the adsorption of N 2 .…”

Sulfur‐Vacancy Defective MoS2 as a Promising Electrocatalyst for Nitrogen Reduction Reaction under Mild Conditions

“…So far, the electrocatalysts designed for electrochemical NRR are mainly the metal‐based materials, such as noble‐metal (Au, Ru, Rh, Pt) [21–25] and non‐precious‐metal (V 2 O 3 , TiO 2 , TiB 2 , Mo 3 Si, Cu 3 P) [26–30] . Moreover, transition metal (TM)‐based single‐atom catalysts (SACs) such as Re, Cr, Fe, and Mo exhibit favorable NRR performance, owing to their empty and occupied d orbitals which can accept lone‐pair electrons and donate to N 2 to destroy the N≡N bond and strengthen the N 2 adsorption on TM [31–34] …”

“…[26][27][28][29][30] Moreover, transition metal (TM)-based single-atom catalysts (SACs) such as Re, Cr, Fe, and Mo exhibit favorable NRR performance, owing to their empty and occupied d orbitals which can accept lone-pair electrons and donate to N 2 to destroy the N�N bond and strengthen the N 2 adsorption on TM. [31][32][33][34] As for nitrogenases, where Mo and S elements play key roles for nitrogen fixation in the biosphere and Mo serves as active center, [35][36][37] several two-dimensional (2D) materials have attracted great interest due to their high surface area and unique electronic structure. [38,39] Among them, a layered ultrathin 2D transition metal molybdenum disulfide (MoS 2 ) has been extensively studied for developments in electrocatalysis, photocatalysis, batteries, and sensors.…”
