ALKALI PROMOTION OF ANTHRACITE OXIDATION BY OXYGEN

The fine-tuning of CuO–CeO2 mixed oxides by means of synthesis procedure (co-precipitation) and alkali promotion (1.0 at Cs per nm2) towards highly active deN2O catalysts is demonstrated.

Alkali Promotion

The hydrophobic gold nanoparticles with monodispersity are synthesized by using n-butanol reduction in situ under the condition of alkali promotion in cetyltrimethylammonium bromide (CTAB)/n-butanol/n-heptane/HAuCl4/NaOH(aq) W/O microemulsion at 30°C. The CTAB-stabilized gold nanoparticles are characterized by UV-vis, TEM , XRD and so on. The replacement of simple surfactant (CTAB ) with mixed surfactant CTAB/ octadecylamine can weaken the direction of CTAB to the growth of gold nanopartices and increase the monodispersity of gold nanoparticles. The effects of components of the microemulsion system on the shape, size and monodispersity of gold nanoparticles are also explored. The results show that the size of gold particles is changed by the amount of CTAB and C18NH2.
