Abstract

Se presenta un nuevo método para la modificación química del TiO2 mediante el dopaje con metales de Fe3+ y Al3+, buscando incrementar su sensibilidad espectral hacia la luz visible para ser incorporados sobre telas de poliéster, empleando dichos sistemas en eliminación fotocatalítica de contaminantes gaseosos. Además, se realizaron dopajes con el método de Ping Yang para comparación. Los sistemas se caracterizaron por DRX, FTIR-ATR, SEM y composición química (AA, EDX). Los resultados confirman la incorporación del metal, siendo el dopaje al 10% (masa) el de mejores características y mejor actividadfotocatalítica respecto al sólido no dopado.
