- •
When Fe and Co species were co-loaded onto activated semi-coke support, there would be a mix crystalline effect increasing the possibility to form oxygen vacancies.
- •
In a synergy surface oxygen vacancy, metal with higher electronegativity would act as the redox site, while another acts as assistance.
- •
At low temperatures, Fe-Co oxides supported by activated semi-coke could adsorb NO species and transform them to nitrites, and with the presence of CO, these nitrites would be decomposed to N2O. While high temperature could promote NO species transforming to coordinated nitrates, which reacted with CO to produce N2.
