Multiple studies have focused on the use of gas detectors based on metal oxides, such as zinc oxide (ZnO), which has specific electronic properties as a gas detector because it is an n-type semiconductor and it has a low production cost. The objective of this work was to analyze the use of ZnO nanostructures for the manufacturing of hydrogen sulfide (H2S) gas sensors, as well as the most common techniques for obtaining these structures. The characteristics of zinc oxide nanostructures (NE´s-ZnO) vary due to the effect of the obtaining method, generating different morphologies and sizes, which impacts gas detection performance (0.5 ppm up to 600 ppm) and in the temperature range that is required. Advances in the design of various NE’s-ZnO will have the possibility of generating sensors that can be used in portable detectors and operate at room temperature, which is a current challenge. Existe un interés global en la detección de gases tóxicos, para la protección del medio ambiente y los seres humanos. Se han desarrollado múltiples estudios enfocados en el uso de sensores de gases basados en óxidos metálicos, como es el óxido de zinc (ZnO), el cual presenta propiedades electrónicas específicas como sensor de gases por ser un semiconductor tipo n y bajo costo de producción. El objetivo de este trabajo fue analizar el uso de nanoestructuras de ZnO, para la fabricación de sensores del gas ácido sulfhídrico (H2S), así como las técnicas de obtención más comunes de dichas estructuras. Las características de las nanoestructuras de óxido de zinc (NE´s-ZnO) varían por efecto del método de obtención, generando diferentes morfologías y tamaño, que impactan en la capacidad de detección de gas (0.5 ppm a 600 ppm) y en el rango de temperatura que se requiere. Los avances en la generación de diversas NE´s-ZnO facilitarán la posibilidad de generar sensores que puedan ser utilizados en detectores portátiles y operen a temperatura ambiente, lo cual es un reto actual.
