(762i) TiO2 Promoted Gold-Based Catalysts for Propylene Epoxidation
In this work, the geometric and electronic effects of gold-titanium based catalysts are studied in detail using a number of in situ characterization techniques, including in situ X-ray absorption spectroscopy and in situ Raman spectroscopy. The loading and location of titanium are precisely controlled by means of atomic layer deposition (ALD). Strategy has been developed to enhance the stability of the gold-based catalysts. The gold-based catalyst regenerated has been studied by applying different post-treatment of the spent catalysts.
