The process of obtaining niobiosilicatos (NBS - 15) nanoporosos with pH adjustment via the buffer solution.

摘要

Patent of invention: "the process of obtaining niobiosilicatos (NBS - 15) nanoporosos with pH adjustment via the buffer solution.The present invention relates to the synthesis process of the material mesoporoso with insertion of niobium by pH adjustment via the buffer solution of potassium chloride and hydrochloric acid.With the characteristics of silicate molecular sieve type nanoestruturado hexagonal ordered number 15.The methodologies relating to the preparation of these materials are reported conventionally, in strongly acid environment which makes the insertion of metals in the structure.In this way, the present invention relates to a process for the synthesis of niobiosilicatos with structure number 15 (NBS - 15, with the direct insertion of niobium by adjustment of pH of the gel.Using KCl / HCl buffer solution.The materials obtained were known as NBS - 15.Where 15 is related to the type of structure is obtained when using the triblock copolymer poliu00f3xido ethylene propylene - ethylene (pluronico P123) as the conductorof structural.The effective control of the acidity of the medium allowed to insert effectively the niobium in the structure of silicate, for the generation of sites of adsorption and catalysis for various industrial applications.The petition 870160045524,
