“…However, WGS reaction is fast over this catalyst, so that it is possible to model the latter reaction as an equilibrium reaction. This is confirmed by several experimental reports [24,[26][27][28]. The parameters of the kinetic models are reported in Tables 1 (Ru/Al2O3), 2 (Ni/Mg/Al2O4), and 3…”

Infrared (IR) thermography is a powerful tool to measure temperature with a high space and time resolution. A particular interesting application of this technology is in the field of catalysis, where new insights to highly dynamic surface reactions are possible. This paper presents guidelines for the development of a reactor cell that can aid in the efficient exploitation of infrared thermography for the investigation of catalytic and other surface reactions. Firstly, the necessary properties of the catalytic reactor are described. In fact, special equipment must be developed to ensure the realization of true operando conditions in the IR thermography experiments. Here, we provide the guidelines to assemble a chemical reactor with an IR transmitting window through which the reaction can be studied with the infrared camera. Secondly, we analyze the requirements towards the catalytic system to be directly observable by IR thermography. This includes the need for a catalyst that provides a sufficiently high heat production (or absorption) rate. We present selected examples of catalytic reactions that can be monitored by IR thermography and showing the potential of the technology in revealing transient and steady state chemical phenomena.

“…An egg-shell catalyst was prepared by dry-impregnation of a rhodium nitrate solution (RhĲNO 3 ) 3 liquid solution, 12.5% wt metal content by Alfa Aesar) on alumina particles with a nominal diameter of 600 μm (PURALOX by Sasol) according to a procedure reported in the literature. 19 The catalyst was prepared while aiming for a final Rh metal content of 0.3% wt with respect to the alumina carrier mass and for an eggshell thickness of 35 μm, which corresponds to 1% wt of metallic Rh with respect to the alumina eggshell mass.…”
