Mesoporous rutile TiO2: Synthesis, characterization and photocatalytic performance studies
Source abstract
Abstract
Abstract Pure rutile phase of TiO2(R-TiO2 ) nanocrystals were synthesized through a low temperature sol-gel synthesis route by tuning the chemical process. This modified process directly resulted in nano spindle structures of rutile TiO 2 at the instant of solvent evaporation and which further found exhibiting stabilized growth upon an increase in calcination temperatures as evidenced by XRD and HR-TEM studies. BET surface area measurement revealed the presence of mesoporosity with a highest surface area of 127.25 m 2/g for the 300 °C calcinated sample. Photo-luminescence studies revealed the presence of intra-band levels at 2.90 eV and 2.68 eV. XPS studies on the highly porous R-TiO2 reveals the presence of Ti3+ ions, which may arise from the missing of oxygen or self-doping. Highly porous 300ᵒC R-TiO2 exhibited in the flat-band potential of -0.39 V as the normalized value for NHE electrode and resulted in the photocatalytic reduction hierarchy of MB > RhB > MO.
