To study the catalytic activity
of mono and bimetallic catalyst, the oxidation of toluene was carried out with hydrogen-peroxide.
It appears that particle size and the mechanism of reaction including the base employed, influences on the catalytic activity
Figure 2 illustrates the catalytic activity
of the immobilized [beta]-galactosidase prepared at different immobilization time.
The highest catalytic activity
of palygorskite among the Russian and Jordanian clay minerals is explained by high content of this mineral in clay sample and the unique needle-like structure of mineral providing high surface area of catalyst and accessibility of active sites for substrate molecules.
Thus, the surface concentration of methoxonium ion, and therefore the catalytic activity
for ring alkylation would depend on the density and strength of the Bronsted acid sites.
The catalytic activity
in the reduction of NO in the presence of hydrocarbons and in the absence of an oxidizing atmosphere was determined as a function of the total conversion of propane and the conversion of NO into N2 by gas chromatography as follows:
The expression and catalytic activity
of neural endopeptidase (NEP) which is involved in degrading beta amyloid was also measured.
Spherical Gel-AuNPs showed excellent catalytic activity
for reduction of three differently charged dyes eosin B (EB), methylene blue (MB) and rose bengal (RB) in the presence of NaBH4.
The catalyst's high level of activity was determined from a systematic experiment (hat studied the catalytic activity
of 10 known compounds, including iridium oxide, which was previously the best known catalyst for hydrogen fuel production.
On the other hand, it is of great importance to investigate the catalytic activity
of low loading platinum catalysts and to determine the lowest metal loading necessary to reach the practical performances in terms of current density and power density because of relatively high cost of catalytic material.
Thus, it is evident that the phytase is denatured during storage at RT, indicating the importance in avoiding long storage periods in order to ensure a satisfactory catalytic activity
The in vitro induction potential of the extracts was tested in freshly isolated human hepatocytes from 3 donors as influence on the catalytic activity
of five cytochrome P450 isoenzymes, namely 1A2, 2B6, 2C9, 2E1, and 3A4 on the respective marker substrates.
