Active Area of Heterogeneous Catalysts: Chemisorption and Temperature Programmed Methods

Does better evaluation of catalyst efficiency and selectivity matter to you? To comprehensively characterize a catalyst, important parameters like metal dispersion, number of active surface sites, redox properties, acidity and activation energy can be measured by various analytical techniques. In our webinar, Dr. Luca Lucarelli, Technology Application Consultant with Micromeritics and highly experienced in the […]

Using Temperature Programed Analysis for Acid Site Characterization of Solid Acids

Zeolites are microporous aluminosilicates that are commonly used as catalysts and adsorbents in many applications. Acid site characterization of a zeolite is crucial to gauge and optimize for a wide variety of different catalytic activities. In this case study, the effect of different SiO2/Al2O3 ratios on acidity of ZSM-5 and the effect of heat on […]

TPR of Copper Oxide Nanoparticles on Alumina – Understanding the Effects of Particle Size and Surface Chemistry

Temperature programmed reduction (TPR) is often used to characterize the reducibility of metal oxides. It is a fingerprint of the reduction of the material as a function of temperature. The peak areas and max peak temperatures gives information on the strength, heterogeneity, and quantity of the reducible species. TPR studies are often repeatable, but a […]

Development of Catalytic Processes for the Conversion of Biomass into Value-Added Chemicals

Biomass is the only renewable and sustainable feedstock for the production of carbon-based fuels and value-added chemicals. Lignocellulosic biomass is the most abundant form of biomass and consists of polymeric sugars (i.e., cellulose and hemicellulose) and lignin, an aromatic, oxygen-containing polymer. This presentation will highlight approaches to valorize both of these main building blocks. The […]
