摘要: Abstract The nitrogen-doped CeO2 powders were synthesized through a mild wet-chemical method followed by calcination in air. results of lattice parameter calculations and XPS analyses suggested that nitrogen was incorporated into the lattice, expansion occurred, accompanied presence Ce3+. Moreover, FTIR analysis revealed possible bonding nature as Ce N bond cubic lattice. showed enhanced oxygen storage capacities with H2 serving probe gas, sample starting N: (mol) = 1.5 maximum consumption (1.49 mmol/g). dominant role nitrogen-induced defects clear for capacities.
