Abstract
Este trabajo estudia el crecimiento y la caracterización de ZnS nanométrico. Las nanopartículas presentan una apreciable fracción de sus átomos en superficie. La efectividad de los nanomateriales se ve incrementada en un grado tal que se requiere una masa significativamente
menor para lograr el efecto deseado. En el estudio se empleó el método de precipitación a
partir de una solución, metodología de trabajo conocida como bottom-up, cuya ventaja consiste en que los precursores en solución se mezclan en una escala atómica. La síntesis puede
hacerse en condiciones cercanas a las del ambiente lo que permite trabajar con equipos
sencillos, de bajo costo y peligrosidad. Se trata de un proyecto de planta para la obtención,
económicamente rentable y con un mínimo impacto ambiental.
This paper studies the growth and characterization of ZnS nano. The nanoparticles have an ap- preciable fraction of atoms on the surface. The effectiveness of nanomaterials is increased to a degree that requires significantly less mass to achieve the desired effect. It was obtained by precipitation from a solution of soluble precursors, working methodology known as “bottom-up”. The advantage of this method is that the solved precursors are mixed on an atomic scale. Synthesis can be done close to ambient conditions. This allows for simple equipment, low cost and danger. Finally, the paper presents a draft plan to obtain ZnS nano, economically profitable and with minimal environmental impact.
