a Schematic illustration of the synthetic process of N doped cerium oxide. b, c Performance of NH3 decomposition reaction at WHSV = 30,000 ml gcat−1 h−1 over Ru on CeO2 and N-CeO2 treated in NH3 at different temperature (b) and duration (c). d Catalytic conversion of NH3 decomposition on Ru/N-CeO2 (650-6) catalyst at different WHSV. e Stability test of Ru/N-CeO2 (650-6) catalyst under NH3 gas flow for 70 h. f Arrhenius plot of Ru/CeO2 and Ru/N-CeO2 (650-6). Error bars represent the mean ± standard deviation from 3 independent measurement. Each measurement was conducted under identical conditions using a freshly prepared batch of catalyst sample.
