The moisture-resistant catalyst for air pollution remediation is a catalyst with moisture-resistant properties, and which is used for removing nitrogen compound pollutants, such as ammonia (NH.sub.3), from air. The moisture-resistant catalyst for air pollution remediation includes at least one metal oxide catalyst, at least one inorganic oxide support for supporting the at least one metal oxide catalyst, and a porous framework for immobilizing the at least one metal oxide catalyst and the at least one inorganic oxide support, where the porous framework is moisture-resistant. As non-limiting examples, the at least one metal oxide catalyst may be supported on the at least one inorganic oxide support by precipitation, impregnation, dry milling, ion-exchange or combinations thereof. The at least one metal oxide catalyst supported on the at least one inorganic oxide support may be physically embedded in the porous framework.

The present disclosure is directed to methods of producing zincoaluminosilicate structures with AEI, CHA, and GME topologies using organic structure directing agents (OSDAs), and the compositions and structures resulting from these methods.

An air conditioning device is disclosed. The present air conditioning device comprises: a photocatalytic filter including a space through which air can pass and having a transition metal oxide formed in a nanotube form on the surface thereof, the transition metal oxide removing gases included in the air and including at least one of TiO.sub.2, ZnO, NiO, and WO.sub.3; and a light source for emitting light to the photocatalytic filter.

A recyclable ceramic catalyst filter, a filtering system including the same, and a method of managing the filtering system are provided. The ceramic catalyst filter has a monolithic structure including a first surface which blocks a first material; and a second surface which removes a second material that passed through the first surface, where the second surface is activated and operates as a catalyst layer which removes the second material in response to energy supplied to the second surface.

A device for processing waste is described herein that comprises an ion generator, a furnace chamber, a heat exchanger, a pollution control system, and a chimney. The ion generator converts atmospheric air into an ionized gas and the furnace chamber thermally decays the waste by combining the waste with a product of an interaction of the ionized gas and heat generated by the furnace chamber. The heat exchanger cools the excess gas. A wet scrubber system removes heavy metals and/or acid gases from the cooled excess gas to generate scrubbed excess gas, and a fixed bed coke system detoxifies the scrubbed excess gas by converting carbon monoxide, water, and steam in the scrubbed excess gas to carbon dioxide and hydrogen, and removing remaining acid gas, a remaining heavy metal, and/or a remaining dioxin from the scrubbed excess gas. The chimney transfers remaining scrubbed excess gas out of the device.

A catalytic composition is disclosed, which exhibits an X-ray amorphous oxide with a spinel formula, and crystals of ZnO, CuO, and at least one Group VIB metal oxide, and preferably, at least one acidic oxide of B, P. or Si, as well. The composition is useful in oxidative processes for removing sulfur from gaseous hydrocarbons.
