    Fabrication, characterization, and photovoltaic performance of titanium dioxide/metal-organic framework composite
    (Elsevier, 2022) Ramaripa, Phuti S.; Modibane, Kwena D.; Ramoroka, Morongwa E.
    The titanium dioxide-metal-organic framework (TiO2−MOF) composite was prepared using the sol-gel method for photovoltaic applications. Raman analyses showed the presence of MOF clusters in the TiO2 sol-gel network. Using the Brunauer-Emmett-Teller method, the resultant composite material exhibited a surface area of 111.10 m2 g−1 as compared to the surface area values of 262.90 and 464.76 m2 g−1 for TiO2 and MOF, respectively. The small optical band gap values of 2.63 for direct electronic transition and 2.70 eV for indirect allowed electronic transition in TiO2/MOF composite were observed using ultraviolet-visible supported by cyclic voltammetry (CV).
