En la presente revisión se consideran los aspectos sobre química ambiental asociados a la fotocatálisis heterogénea bajo luz solar basada en TiO2 y Bi2WO6; se destaca el mecanismo generalizado de formación de radicales libres, se discute sobre las estrategias empleadas para la mejora de los procesos de conversión de energía en el material en estado sólido, así como, en la interfase por moléculas adsorbidas. Se discuten los aspectos asociados a la creciente investigación sobre sistemas fotocatalíticos basados en el óxido Aurivillius más simple: el Bi2WO6, considerando los conceptos claves que definen la conversión de energía y, finalmente, se comentan diversas perspectivas sobre desarrollos ambientales que pueden resolverse con la implementación de la tecnología de fotoelectrocatálisis basada en nanomateriales.
