Microcalorimetric study of ammonia chemisorption on H3PW 12O40 supported onto mesoporous synthetic carbons and SBA-15
Keggin tungstophosphoric acid supported onto mesoporous and meso-microporous materials was studied by ammonia microcalorimetry. Experiments were performed at high and low temperatures to separate the contributions of chemisorpdon and physisorption, low-temperature data being potentially important for the ambient temperature purification processes. Analysis of thermokinetic data obtained from heat
