Abstract
Se ha obtenido óxido de grafeno (GO) laminar por el método de Hummers modificado con un tamaño medio de 9±3 |im y sulfuro de estaño (SnS2) con distinto tamaño medio entre 60 ± 20 nm hasta 375 ± 75 nm por el método innovador hidrotermal/atrano. En base a estos métodos se sintetizó un material compuesto SnS2/GO. Este producto fue evaluado como fotocatalizador para la degradación de iones CN- en condiciones estandarizadas con radiación electromagnética visible. La capacidad de degradación de los materiales obtenidos presentan el orden SnS2/GO > SnS2 > GO.
Lamellar graphene oxide (GO) was obtained by the modified Hummers method with an average size of 9 ± 3 um and tin sulphide (SnS2) with different sizes between 60 ± 20 nm and 375 ± 50 nm by the innovative method hydrothermal/atrane. Based on these methods, a SnS2/GO composite was synthesized. This product has been evaluated as a photocatalyst for degradation of CN- ions under standardized conditions with visible electromagnetic radiation. The degradation capacity of the materials obtained are presented in the order SnS2/GO>SnS2> GO.
