Resumen
En este trabajo se discute un marco de interpretación experimental del desplazamiento electrónico de un sitio catalítico. Aunque esta interpretación no es nueva, se cree que es importante presentar este contexto mencionando los ejemplos obtenidos hasta ahora en dos soportes diferentes, como son, el carbono grafítico y los óxidos semiconductores. Los cambios en la propiedad electrónica de los sitios catalíticos tienen el efecto de modificar la energía de adsorción de la especie reactiva, como se discute utilizando el monóxido de carbono como sonda molecular.
