Abstract:
Disclosed are a vanadia-titania aerogel catalyst having high specific surface area and porosity, a method of preparing the same and a method of completely oxidatively-decomposing a chlorinated aromatic compound using the catalyst under air condition. The vanadia-titania aerogel catalyst of the invention is an aerogel form having many porosities and a high specific surface area obtained by performing a supercritical drying of vanadia-titania wet gel, which is prepared by a sol-gel method, with carbon dioxide and then firing the dried vanadia-titania, with a micro porosity structure being maintained, consists of vanadia and titania wherein a content of the vanadia is 1˜15 wt % of an overall catalyst weight. In addition, according to the invention, the vanadia-titania aerogel catalyst may further comprise a manganese oxide of 1˜5 wt % or a sulfur component of 0.0001˜1 wt %. Since the vanadia-titania aerogle catalyst of the invention has the very high conversion rate and selectivity for the complete oxidation reaction of the chlorinated aromatic compound and is very thermally stable, it can be usefully used in the oxidation reaction having a high heating value capable of generating local heat spots.
Abstract:

Abstract:
A method for managing the applications related to data broadcasting, a class/interface structure for controlling the same, and a broadcasting receiver for controlling the class/interface receiver can prevent data broadcast-associated application from conflicting with a Native application. The method comprising the steps of: pausing an application associated with a cable mode if a current input mode is not in cable mode; and controlling a broadcast receiver by using an application that is native to the broadcast receiver.
