Abstract

SE PRESENTA UN FOTOCATALIZADOR PARA LA PREPARACION DE HIDROGENO QUE CONSTA DE UN INGREDIENTE DE CESIO CATALITICAMENTE ACTIVO (CS) IMPREGNADO EN UN SOPORTE DE K{SUB, 4}NB{SUB, 6}O{SUB, 17}, REPRESENTADO POR LA FORMULA (I): CS(A)/K{SUB, 4}NB{SUB, 6}O{SUB, 17}, EN DONDE A ENTRE PARENTESIS DENOTA LA CANTIDAD DE UN INGREDIENTE DE CS CATALITICAMENTE ACTIVO IMPREGNADO EN EL SOPORTE K{SUB, 4}NB{SUB, 6}O{SUB, 17} Y TIENE UN VALOR DE 0.05 Y 5.0% DEL PESO EN BASE A PESO TOTAL DEL SOPORTE. EL CATALIZADOR SE PREPARA COMBINANDO K{SUB, 2}CO{SUB, 3} CON NB{SUB, 2}O{SUB, 5} EN UNA PROPORCION MOL DE 2:3 DE K{SUB, 2}CO{SUB, 3}:NB{SUB, 5} AGLUTINANDO LA COMBINACION A UNA TEMPERATURA DE ENTRE 1200 (GRADOS) Y 1300 (GRADOS) C, PARA OBTENER K{SUB, 4}NB{SUB, 6}O{SUB, 17}, UN SOPORTE; E IMPREGNANDO EL SOPORTE CON UN INGREDIENTE DE CS INORGANICO CATALITICAMENTE ACTIVO. EL HIDROGENO SE PRODUCE DE FORMA EFICIENTE ILUMINANDO CON LUZ ULTRAVIOLETA SOBRE UNA SOLUCION ACUOSA AÑADIDA CON UN PROMOTOR ORGANICO QUE CONTIENE OXIGENO A UNA TEMPERATURA DE REACCION DE ENTRE 15 (GRADOS) Y 80 (GRADOS) C BAJO UNA PRESION DE REACCION DE ENTRE 0.1 Y 3 ATM, EN LA PRESENCIA DEL FOTOCATALIZADOR.
