Validation of a newly developed FTIR in situ reactor: Real time study of photocatalytic degradation of nitric oxide

Photocatalytic degradation of ethylene: An FTIR in situ study under atmospheric conditions

“…For this study we have used the FTIR in situ reactor as described in our previous work [2], with this difference that a bigger aperture 0926-3373/$ -see front matter © 2011 Elsevier B.V. All rights reserved. doi:10.1016/j.apcatb.2011.03.041 was applied.…”

“…There is still some uncertainty, however, on the exact reaction pathway for these pollutants. Therefore, our lab has developed a FTIR in situ reactor, which allows us to follow the intermediates that are adsorbed on the catalyst surface at the moment the reactions occur [2].…”

Concept and Validation of a Fully Automated Photocatalytic Test Setup

“…By using specialized instruments, further insights can be obtained for this different behavior. 13 The automated setup makes it possible to repeat the experiment several times, resulting in several time-identical measurements in varying reaction conditions. A complete set of experiments is obtained that can be analyzed toward the degradation potential for all the concentrations and conditions.…”

Effect of pretreatment and temperature on the properties of Pinnularia biosilica frustules

“…The bands at 3444 and 1626 cm À1 can be assigned to stretching and bending vibration of surface hydroxyl groups respectively. 24 The intensity of these bands in the biosilica samples calcined at 550 C is much stronger compared to the sample calcined at 750 C, indicating a loss of surface hydroxyl groups at high temperature. This can be explained by sintering of the pores at high temperature, resulting in a decrease of surface area and thus a loss in surface hydroxyl groups.…”
