Abstract: A process for producing a catalyst, comprising the steps of modifying a carrier by a first impregnation with at least one alkaline earth metal in a first metal precursor solution, the first metal precursor being decomposed to form at least one metal oxide or metal hydroxide, thereby obtaining a modified carrier. A second impregnation is carried out by incipient wetness by a second precursor solution comprising at least one metal Me in a second solution. Finally, the second precursor is decomposed, thereby obtaining a catalyst body having an enrichment of the at least one metal Me in the outer shell of the catalyst body, the metal being present in a concentration having either as an egg-shell profile or a hammock profile.

Abstract: A conditioning process that is employed with a high selectivity catalyst (HSC) during an initial phase (i.e., start-up) of the epoxidation process is provided. The HSC conditioning process of the present disclosure ensures that the heat release from a catalyst bed containing an HSC during a start-up operation is less than 2000 kJ/Kgcat·hr. The HSC containing catalyst bed that has been conditioned by the process of the present disclosure exhibits improved performance (i.e., EO selectivity) and reduced hot spots.

Abstract: Disclosed are a photocatalyst and application thereof in environmentally friendly photocatalytic treatment of a power battery. The photocatalyst is obtained by loading Ag—TaON on a hollow glass microsphere, wherein a mass ratio of the Ag—TaON to the hollow glass microsphere is 1:5 to 10. According to the invention, the Ag—TaON and the hollow glass microsphere are compounded, the hollow glass microsphere has better light permeability, which avoids mutual shielding between catalysts, such that the photocatalyst filled in a reactor is fully excited, which is capable of effectively improving a light utilization rate, thus improving the catalytic conversion efficiency of the photocatalyst.

Abstract: A supported catalyst having rhodium particles with an average diameter of less than 1 nm disposed on a support material containing magnetic iron oxide (e.g. Fe3O4). A method of producing the supported catalyst and a process of reducing nitroarenes to corresponding aromatic amines employing the supported catalyst with a high product yield are also described. The supported catalyst may be recovered with ease using an external magnet and reused.
