The design was developed and a hardware-software measuring infrared thermography-based complex, which allows semi-automatic experimental research of the sorption dynamics and low-temperature catalytic processes during the interaction of various gases and their mixtures with solid-state highly dispersed materials, was created. The complex contains an optical-mechanical part and an automated gas supply system controlled via WiFi. Using the new-generation infrared thermography methods, the latent kinetics of phase transformations on the surface of highly dispersed samples with catalytic and non-catalytic properties has been experimentally investigated. The quantitative characteristics of fine-grained materials have been experimentally studied. Using the described methodology, a number of interesting phenomena taking place on the surface of highly dispersed media were experimentally revealed.
