In addition to this wide array of functions, antibodies under certain conditions also exhibit an enzymatic or catalytic activity
and are called "abzymes" (antibody enzymes).
These low-coordinated active atoms and contiguous oxygen ions may play the role of heterojunctions that synergistically facilitate the Volmer process and thus render stimulated HER catalytic activity
, corresponding to a faster electron transfer and more facile HER kinetics at the electrode/electrolyte interface.
. The catalytic performance of the bifunctional catalyst was investigated by hydrotreating Jatropha curcas seed oil in a continuous flow tubular reactor of 9 mm internal diameter and 300 mm in length vertically within the tubular programmable temperature.
. Esterification of acetic acid with 1-heptanol was performed using a three-neck flask under atmospheric pressure at 90[degrees]C.
Compared with N/S/F-CNTs, the other two catalysts exhibited evidently worse catalytic activity
. The value of electron transfer number for N/S/F-CNTs was close to 4.0, which was calculated from Koutecky-Levich curves with a potential range of -0.4 V to -0.50 V [25-27].
Compared with [Fe.sub3][O.sub.4], [Co.sub3][O.sub.4] microspheres, [V.sub6][O.sub.13] nanobelts, and [alpha]-[Fe.sub.2][O.sub.3]/C, the [M.sub.2][O.sub.3]/CNTs showed better catalytic activity
in the thermal decomposition of AP.
It appears that particle size and the mechanism of reaction including the base employed, influences on the catalytic activity
. A higher particle size favors the oxidation at intermediates, and distinct mechanisms of reaction with NaOH or CaC[O.sub.3] are followed.
Previous research found that the catalytic activity
increases as the while line intensity decreases .
The effect of variation EDA concentration on the catalytic activity
was investigated (Figure 1).
Those carbonaceous materials that have a high specific surface area show higher catalytic activity
On the other hand, ionic compounds are constituted in an ion-pair configuration, where the cationic species (commonly anilinium or carbonium) takes the function of activating the alkylated active sites, while the anionic species (tetra(pentafluorophenyl)borate) prevent the interaction between the abstracted methyl and the Zr center (1), therefore the catalytic activity
The types of stabilizers and concentration, the solvent polarity , and the aging time of colloidal suspensions  can have an effect on the size, shape and catalytic activity
of palladium nanoparticles.
