Abstract
A method to predict the catalytic activity of a metal oxide of formula MOwhere x is a number from 1 to 3 and y is a number from 1 to 8 is provided. The metal of the metal oxide has redox coupled oxidation states wherein the redox transformation is between oxidation states selected from the group consisting of a diamagnetic oxidation state (M) and a paramagnetic oxidation state (M), a paramagnetic oxidation state (M) and a ferromagnetic oxidation state (M), and a paramagnetic oxidation state (M) and an antiferromagnetic oxidation state (Mwhere d, p, f and a are independently numbers from 1 to 6 and one of the oxidation states (M), (M), (M), and (M) is formed by reduction by the O. The magnetic susceptibility of the metal oxide as a sample in an oxygen environment at a specified temperature is correlated with a value of (Mor Mor Mor M)/g (Orich). Then the magnetic susceptibility of the metal oxide as a sample in an oxygen free environment at the specified temperature is measured and correlated with a value of number of (Mor Mor Mor M)/g (Odeficient). The catalytic activity is predicted based on the difference of these two numbers.
