Four perovskite-type complex oxides (LaNiO3, La2NiO4, LaCoO3 and La2CoO4) were suc-cessfully prepared using two sol-gel methods, the Pechini method (PC) and the
NOx-catalyzed oxidation of methane without a solid catalyst was investigated, and a hydrogen selectivity of 27% was obtained with an overall methane conversion
A novel method to prepare mesoporous nano-zirconia was developed. The synthesis was carried out in the presence of PEO surfactants via a solid-state reaction. T
The acidic modulations of a series of HZSM-5 catalysts were successfully made by calcination at different treatment temperatures, i.e. 500, 600, 650, 700 and 80
