Resumen
La fotocatálisis es una reacción química inducida por la absorción de un material sólido, o fotocatalizador. La excitación del sólido desencadena dos reacciones que conducen a la formación casi instantánea de radicales hidroxilos y aniones superóxido (llamadas especies reactivas de oxígeno; ROS). Los ROS producen daño oxidativo en diversos microorganismos incluyendo al virus SARS-CoV2, favoreciendo la desintegración de la conformación proteica de la cápside, cambios en la permeabilidad y daños de la membrana del virión que finalmente conduce a rotura del ADN, sin la oportunidad de reparación. Incluso, la reacción fotocatalítica causa la degradación oxidativa contra materiales peligrosos orgánicos y/o inorgánicos en el aire para convertirlos en sustancias no dañinas como agua o dióxido de carbono.
