Efficient catalytic decomposition of N2O over Cd-doped NiO in the presence of O2

Enhanced electrocatalytic glucose oxidation assisted hydrogen production via the interfacial synergistic effect of NiO/NiCo2O4 porous nanowires

“…The predominant peak shift by 15 cm −1 from 1551 (NiO) to 1566 cm −1 (NiO/NiCo 2 O 4 /NF-300) indicates that the original chemical environment of NiO was affected, further demonstrating the presence of charge transfer at the heterojunction interface between the two components. 41,42…”

As shown in Fig.…”

Dispersed Pr on Nickel Oxide for Efficient Nitrous Oxide Direct Decomposition in Simulated Nitric Acid Exhaust

“…16−18 For NiO, deN 2 O initiates with N 2 O adsorption onto the catalyst, leading to its breakdown into N 2 and adsorbed oxygen (Ni−O*). 19,20 This is followed by either the recombination of two O* (L-H mechanism) or their interaction with another N 2 O molecule to form O 2 (E-R mechanism). 21 The Ni 2+ is identified as the key center for deN 2 O due to its electrondonating capability.…”

Mechanistic Insight into the Promotion of the Low-Temperature NH3–SCR Activity over NiMnFeOx LDO Catalysts: A Combined Experimental and DFT Study

“…The difference in regeneration depended on the formation of the sulfate species. Moreover, Chang and co-workers , have scientifically explained the decomposition mechanism of N 2 O, the mechanism of catalyst poisoning, and the synergistic removal of gaseous pollutants. Fe-based catalysts can promote the NH 3 selective catalytic reduction (NH 3 –SCR) reaction of NO x and accelerate the adsorption of NH 3 species, which surprisingly exhibit excellent SO 2 resistance and thermal stability .…”
