英文摘要a microcalorimetric device for the measurement of differential heat of adsorption on the surface of solid catalysts is described. in the device, a setaram heat flow microcalorimeter is used to measure the heat evolved from the sample. at the same time, an mks baratron capacitance manometer connected to a high vacuum system is employed to measure the amount of gas adsorbed on the sample. besides, a special all-metal vessel for the measurement of differential heat of adsorption on highly active catalysts, which can be operated under the conditions of high vacuum and wide temperature range, was designed and constructed. the microcalorimeter was calibrated with standard materials. the measurement of differential heat of adsorption such as h-2 on pt/sio2 and gamma-mo2n was carried out. the pt/sio2 sample was prepared by impregnation of silica with acetic solution of h2ptcl6.6h(2)o and the gamma-mo2n sample was prepared by temperature-programmed reductive nitriding of highly pure moo3 in a flow of pure nh3. the experimental results for the adsorption heat are in good agreement with those published in the literature. the error analysis of the experimental data shows that the relative errors for the measurement of adsorption heat are within 4%.
