Morphology-dependent electrocatalytic nitrogen reduction on Ag triangular nanoplates

Abstract

Ag triangle-nanoplates and potassium cations can synergistically promote electrocatalytic nitrogen fixation in aqueous solutions under ambient conditions.

High yield selective electrochemical conversion of N2 to NH3via morphology controlled silver phosphate under ambient conditions

“…52 In addition, superior activity of Ag 3 PO 4 (2 h) towards the e-NRR can also be credited to its cuboidal morphology which would offer exposed active sites for N 2 adsorption preferentially by virtue of the atoms present at the sharp edges over its surface and drive the e-NRR at lower overpotential. Surface atoms located at sharp edges, corners or stacking faults shift valence bands up, allowing stronger dinitrogen adsorption than surface atoms located at basal planes 57 which is in agreement with our obtained results.…”

Current Progress of Electrocatalysts for Ammonia Synthesis Through Electrochemical Nitrogen Reduction Under Ambient Conditions

“…The above-mentioned Au nanocage catalyst prepared with the Ag nanocage as at emplate shows high catalytic activity, [30] and the Ag used as at emplate, ac ommon noble metal, has also shown activity for NRR. Gao et al [44] successfully prepared Ag triangular nanoplates (AgTPs) and used them as NRR catalyst. At À0.25 Vv s. RHE, the AgTPsc atalyst achievedaFE of 25 %, with an NH 3 yield rate of 58.5 mg h À1 g Ag…”

Facile fabrication of functional cellulose paper with high-capacity immobilization of Ag nanoparticles for catalytic applications for tannery wastewater

“…The largest peaks were observed from GA@AgNPs-LA-CP. Furthermore, compared to the XRD curves of CP samples without other crystal diffraction peaks, for both GA@AgNPs-CP and GA@AgNPs-LA-CP, The Bragg reflection peaks of 2θ arise at 33.5°, 46.4°, 66.8°, and 77.5°, which are coincident with the (1 1 1), (2 0 0), (2 2 0), and (3 1 1) facets of the face-centered cubic structure of crystalline Ag and indicate the immobilization of GA@AgNPs on cellulose fibers, respectively [41,48]. Lower peak intensities were observed in the GA@AgNPs-CP samples and most peaks were in similar locations.…”
