Quantachrome Instruments Catalysts - Important Aspects Of Chemical Adsorption Characterization

The ever increasing demand to develop highly efficient catalytic processes in many different industries including the automotive, petro-chemical, pharmaceutical and food processing ones coincides with the necessity to minimize their environmental impact (air/soil pollution, waste storage and elimination, harmful by-products, …). Increasingly strict emission/safety regulations coupled with fluctuating metal and rare earth prices create novel challenges for the development of innovative and cost-competitive (emission) catalysts. As a result, comprehensive characterization of such materials has become mandatory in order to optimize their efficiency. Among the portfolio of available techniques, chemical adsorption characterization play a crucial role as accurate assessment of the effective adsorbed quantities in realistic conditions as well as knowledge about active metal area, metal dispersion, crystallite size, heats of adsorption and acid sites strength is, more than ever, of prime importance. In this Webinar, we will review important aspects and current challenges regarding the state-of-the-art chemical adsorption characterization of these high-added value materials. A brief reminder about physical adsorption characterization of supported catalysts will also be discussed.
