Webinar - TPR of Copper Oxide Nanoparticles on Alumina - Understanding the Effects of Particle Size and Surface Chemistry (8 December 2021)

Location: Online

Date: 8th December 2021

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 change in the experimental conditions or preparation of the material can affect the results. Due to this complexity, experimental conditions are selected based on models such as Monti and Baiker – which considers the selection based on the heating rate, hydrogen concentration, total flow rate, and the amount of reducible material. In this webinar – we will explore this further using copper oxide on alumina support and present the effects of particle size, surface chemistry and how that effects the reduction fingerprint.

  • Learn how to select an analysis condition using models such as Monti and Baiker.
  • Understand how Temperature Programmed Reduction is affected by the analysis condition.
  • Understand that other factors such as particle size and the surface chemistry of the supporting material can alter the TPR fingerprint with a case study using copper oxide on alumina support.
