peak assignment software using Cu K α radiation (λ = 1.54 Å). All the diffraction patterns were recorded in 2θ range of 20–80° by a scanning rate of 2° min −1 .
Temperature programmed desorption (TPD) experiments on 0.1 g of catalyst were
electron microscopy (SEM), X-ray powder diffraction (XRD), temperature program reduction (TPR), and temperature program desorption (TPD) techniques and catalytic measurements have been operated to determine their properties and catalytic performances

obtained by NH 3 -TPD on a Quantachrome Chembet 3000 chemisorb apparatus. In the first heating before NH 3 -TPD analyses, heating was carried out in He. The samples were first heated at 873 K for 1 h and then cooled to 423 K. Then NH 3 adsorption was
composition of the PM samples were analyzed by so-called temperature-programmed desorption followed by oxidation (TPD/O) experiments. During such experiments the samples were heated first under inert conditions (here: nitrogen atmosphere) to 700 °C with 20 K

reaction. These materials were characterized by N 2 adsorption measurements, X-ray diffraction (XRD), MET, temperature-programmed desorption (TPD) of pyridine and 71 Ga MAS-NMR spectroscopy.
Sol-gel-derived titania films were analyzed by temperature programmed desorption (TPD) and X-ray diffraction (XRD) techniques.
The relationship between the TPD curves measured for two types of titania gel films and their crystal structures was investigated.
On the basis of the analyses, a preparation process for a titania sol solution containing anatase nanocrystals was designed
and developed. Using this process, a colloidal anatase titania sol solution was prepared by heating aqueous titanium hydroxide
containing HCl at 60�C for 2 h. The nanocrystal structure of the titania films obtained by coating the sol on glass substrates
was confirmed by TPD and XRD measurements.
The interactions of propylene with zinc oxide have been studied by temperature-programmed desorption (TPD) under experimental conditions free of inter- or intraparticle limitations or readsorption phenomena.
