Oxygen vacancies enhance the photocatalytic deep oxidation of NO over an N-doped KNbO3 catalyst

Abstract: A N-doped KNbO3 (N-KNbO3) was prepared through urea and KNbO3 mechanically mixed grinding and calcination. The photocatalytic NO oxidation performance was evaluated at room temperature and under visible light irradiation....

“…Furthermore, it could be seen that the diffraction peak (222) is slightly shifted to the lower 2θ direction from the enlarged XRD patterns (Figure S8). On the one hand, it is due to the introduction of Co 3 O 4 and Au; on the other hand, nitrogen doping will change the disorder of the crystal structure . The presence of Au and Co 3 O 4 in the Au/N–In 2 O 3 /Co 3 O 4 DSHDs was further confirmed by XPS analysis, as described below.…”

“…The metal-support interaction strongly influences the hydrogenation of lignin model compounds and other biomass-derived platform chemicals, and the selection of support can lead to additional benefits, such as altering active sites and facilitating the adsorption of reactants. Recently, the reducible properties and oxygen storage capacity of niobium oxide have attracted considerable attention as it provided strong metal-support interaction and facilitated decorating metals with tunable oxidation states, affecting catalytic activity. , Niobium oxide has been extensively investigated for various applications, and metal-decorated Nb 2 O 5 has also been evaluated due to its strong metal-support interactions. Therefore, modification of the niobium oxide properties and utilization in hydrogenation reaction is of significant interest.…”
