Background Temperature programmed oxidation (TPO) is a versatile materials characterisation tool used in catalysis for the elucidation of surface chemistry in catalytic materials. The underlying principle of the technique is simple, hydrogen or oxygen are passed over...
Background Chemisorption, as opposed to physisorption, is a strong interaction between the adsorbed molecule and the surface of the molecule of the active site. Pyridine is a base molecule that strongly interacts and chemisorbs over the acid sites of studied...
Problem A customer aimed to improve the activity and stability of an industrial catalyst establishing understanding relationships between the catalyst recipe, its structure, and performance. Which analysis? Stoli studied coordination and oxidation state of the active...
Problem A major company was developing a novel reactor and required synthesis of thermally-conductive catalyst-coated tubes. These reactors applied to a gas-phase process would minimise heat and mass transfer compared to powdered catalyst. The resulting benefits...
