Este protocolo guía la fabricación y el análisis electroquímico de electrocatalizadores bimetálicos de CuZn y NiCo soportados por MXene para la producción de combustibles verdes a partir de dióxido de carbono y agua utilizando energía solar.

El ámbito de nuestro trabajo abarca en términos generales la síntesis, caracterización y análisis de nuevas películas de aglutinantes disruptivos y catalizadores libres para producir combustibles solares a partir de agua y dióxido de carbono. Los principales retos en el campo incluyen bajas eficiencias paraicas en tasas de producción adecuadas, catalizador a largo plazo, durabilidad y escalabilidad del sistema. Para empezar, limpia la espuma de níquel usando acetona y luego sonica la espuma de níquel en agua desionizada durante cinco minutos.

Bajo la campana extractora, remojas el papel de fibra de carbono en un molar de ácido nítrico durante 20 minutos para activarlo mientras llevas guantes y el equipo de protección personal adecuado. Sumerge la espuma de níquel limpia y la solución de MXene durante cinco minutos. Después de secar la muestra, etiquétala como espuma de níquel MXene.
