The effect of Ag as a promoter for Ru/CeO2 catalysts in ammonia synthesis

Favoring the unfavored: Selective electrochemical nitrogen fixation using a reticular chemistry approach

“…The need of a higher overpotential to drive NRR and poorer Faradic efficiency therefore indicates that it is more difficult for N 2 to be electrochemically reduced in a single metallic Au@ZIF platform. These observations therefore clearly exemplify the necessity of inherently stronger catalytic activities, either conferred by synergistic effect of bimetallic system or other NRR catalytic materials ( 30 ), to further promote reaction efficiency and offer distinct electrochemical responses for reaction studies. These findings also highlight that our electrocatalytic design is versatile and can be possibly build-on traditionally highly active Ru/Fe/Mo-based catalysts to confer NRR selectivity critical for overcoming their current performance bottleneck imposed by water poisoning ( 13 ).…”

Noble metal ion substituted CeO2 catalysts: Electronic interaction between noble metal ions and CeO2 lattice

“…Other metal ions are also in ionic state as can be found from their binding energies compiled in Table 3. Noble metal ions dispersed on CeO 2 support reported by several research groups confirming ionic nature of noble metal ions in CeO 2 are also given in the table [89,99,[127][128][129][130][131][132][133][134][135][136].…”

Reactions of ethanol over CeO2 and Ru/CeO2 catalysts

“…Its introduction onto CeO 2 and (CeZr)O 2 has shown benefits for hydrogen production from glycerol [22]. Ru based catalysts have been studied previously for steam reforming of ethanol [23], oxidative steam reforming [24], CO 2 activation [25] ,and ammonia synthesis [26].…”
