One of the most known physical chemists Wilhelm Ostwald defined catalyst as a substance that
participates in a particular chemical reaction and thereby increases its rate but without a net
change in the amount of that substance in the system [1-3]. Hereinafter catalyst will referred as
the common name for both, catalyst and inhibitor, where inhibitor has an opposite role decreasing
the rate of chemical reaction. Having such important function in chemical kinetics and different
applications, catalysts are the permanent subjects of scientific investigations. These investigations
contain discovering of new catalysts, determining their physicochemical characteristics, and
examinations of their influence on particular reactions. By the interaction between catalyst and
reaction system, the control of considered process, as well as the characteristics of catalyst, can
be analyzed in parallel. If our aim is the investigation of catalyst characteristics, the selection of
reaction system as a matrix for its examination is of great importance. Therefore, we discussed
in the following the different reaction systems including their main characteristics important for
mentioned investigations (Sections I.A and I.B) with particular attention on oscillatory reactions
in general (Section II) and Bray-Liebhafsky [4,5] in particular (Section III). In Section IV, the
characterization of the catalysts by means of the Bray-Liebhafsky oscillatory reaction as the
matrix system will be presented.
