摘要：
In the air tonight: High adsorptive desulfurization capacity of commercial diesel was achieved by using TiO2-CeO2 mixed-oxide adsorbents with the addition of air. Density functional theory elucidated a cyclic adsorption process, in which surface-oxygen vacancies on the Ti 0.9Ce0.1O2 surface served as active sites. Copyright © 2013 WILEY-VCH Verlag GmbH & Co.
