OXIDES, CATALYTIC ACTIVITY

Table 1 gives the results of physicochemical analysis of the various zinc oxides. Catalytic activity of zinc oxides towards decomposition of propan-2-ol is also presented in Table 1. Chemical analysis of zinc showed results close to stoichiometry except for Z. ...

Lu et al. [50] investigated the OCM in a tubular membrane reactor, which consisted of two layers, with SrFeCoo.sOs as the MIECM and BaCeo.6Smo.4O3 as the secondary layer deposited inside the SrFeCoo.sOs tube to minimize the effect of the total oxidation catalytic activity of SrFeCoo.sOs. La/MgO as OCM catalyst was added inside the reactor. C2 product yields of up to 7% were reported. 

Scheme 12.5 The presence of task-specific ligands around gold nanoparticles makes it possible to template the formation of a mesoporous silica with aerobic oxidation catalytic activity.

Stohr and Boehm [29] studied the enhancement of oxidative catalytic activity of active carbons treated with ammonia or cyanhydric acid at 600 to 900°C. 

Recent studies demonstrated that the oxidation catalytic activity of perovskite materials is closely correlated with the stability of oxygen vacancies. Based on a...

The supported HPAs exhibit higher catalytic activity in propylene oxidation than the bulk ones and favoured the formation of acrolein, acetaldehyde and acetic acid, compared to the mother catalysts which lead only to the formation of COx. The enhanced oxidation catalytic activity of supported systems was attributed to the fine dispersion of H3+xPMoi2-xVx04o species on the CMI-1 mesoporous material via physical adsorption, together with the fact that the stracture of both CMI-1 and HPAs remained intact during the impregnation. 

Instead of coating the surface of the particles, doping with Fe ions can induce decreased photoactivities of nanocomposite materials. In Ce02 nanopartides doping with Ca leads to higher UV-absorption and reduced their oxidation catalytic activity.
