MOF-derived Co2+-doped TiO2 nanoparticles as photoanodes for dye-sensitized solar cells

Abstract Facile synthesis and application of nano-sized semiconductor metal oxides for optoelectronic devices have always affected fabrication challenges since it involves multi-step synthesis processes. In this regard, semiconductor oxides derived directly from metal–organic frameworks (MOFs) route...
