Title
Low-temperature water gas shift reaction over Pt–Re/TiO2 catalysts prepared by a sub-critical drying method
Abstract

In order to prepare a highly dispersed Pt–Re/TiO2 (R: rutile) catalyst with superior catalytic activity for the low-temperature water gas shift reaction (LT-WGS), the effect of the drying conditions after impregnation on the catalytic properties and activity of Pt–Re/TiO2(R) catalysts was examined. As a result, sub-critical drying (SubCD), where the catalyst is dried under sub-critical conditions, was effective for the enhancement of Pt dispersion and for resisting Pt loss during the drying step. The SubCD catalyst prepared with Pt(C5H7O2)2 exhibited superior catalytic activity for LT-WGS at 250 °C compared with that of a commercial Cu/Zn catalyst.
