Photodecomposition of gaseous toluene using TiO₂ prepared by SANSS

Concepts of Nanoparticle Dose Metric and Response Metric

“…He derived his value on the basis of the specific density of TiO 2 (anatase) and a spherical primary particle size of 20 nm. BET surface area for this TiO 2 (Degussa P25) has been measured independently by a number of investigators, including our group ( Jwo et al 2005 ; Long et al 2006 ; Wahl et al 2005 ), and ranges between 48 and 55 m 2 /g. There is no reason to mathematically manipulate this number to a value that is completely at odds with actual measurements.…”
