- W3204333709 abstract "• Inactive Au/TiO 2 can be activated by Cl radicals. • Once Cl is consumed, the reaction will be terminated, although a large amount of supported cationic Au remains. • The Au(I)–Au(III) redox couple is responsible for triggering the reaction. Supported cationic gold (Au) has been recognized as an active site of acetylene hydrochlorination for decades; however, it remains ambiguous why its loading on carbon-based materials is active but that on metal oxides (e.g., titania, TiO 2 ) is virtually inactive. For the inactive Au/TiO 2 catalyst, the Au(I)–Au(III) redox couple cannot be constructed in the presence of oxidizing gas (NO, N 2 O, and NO 2 ), which is thermally desorbed from the catalyst synthesis when aqua regia is used. Surprisingly, the inactive Au/TiO 2 can be activated when it is impregnated with trichloromethane, CHCl 3 , which releases the radical ( Cl) to trigger the Au(I)–Au(III) redox couple. Once Cl radicals are consumed, the reaction will be terminated, although a large amount of supported cationic Au remains. The terminated Au/TiO 2 catalyst can be reactivated by adding Cl again. In contrast to the carbon-supported cationic Au system, the inability to build Au(I)–Au(III) redox couples is the dominant reason for the inactivity of metal-oxide-supported Au catalysts and provides a new perspective on activating metal-oxide-supported metal-based hydrochlorination catalysts." @default.
