A two-dimensional MXene-supported metal–organic framework for highly selective ambient electrocatalytic nitrogen reduction

Abstract

A Co-based MOF supported on Ti3C2 MXene was prepared via in situ growth, which can efficiently reduce nitrogen to ammonia under environmental conditions.

Recent advances in material design and reactor engineering for electrocatalytic ambient nitrogen fixation

“…The advanced catalysts for efficiently promoting the N 2 fixation performance are discussed in this section (Table 1). 82–146 Given that the reaction potential range of the NRR overlaps with that of the HER and it has a higher kinetic barrier in comparison, most of the catalysts reported thus far are dominated by the competitive HER reaction under the reaction conditions. Consequently, the FE for the production of NH 3 is often less than 20% and the NH 3 yield is also 2–3 orders of magnitude lower than that of industrial catalysts.…”

Fe‐based catalysts for nitrogen reduction toward ammonia electrosynthesis under ambient conditions

“…Some transition metals (Co, 93‐96 Cu, 97 Ti, 99,100 and V 101,102 ) and rare earth metals (Ce 103 ) also have common cofactors for Fe, enhancing the electrocatalytic NRR performance. We summarize a series of Fe‐M (Co, Cu, Ti, V, and Ce) materials in this section to study the activity and stability of Fe‐M catalysts.…”
