In the present research work a potentially improved Copper (Cu) and Boron (B) codoped TiO2 nano materials were synthesized by varying the different dopant concentrations (Copper 0.25, 0.50, 0.75, 1 wt % and Boron 0.25, 0.50, 0.75, 1 wt%) using solgel method for the photocatalytic degradation of Lissamine Green B.
In order to investigate the physical, chemical and optical properties of a catalyst, which play a key role in its photocatalytic activity, as prepared samples were characterized by various instrumental techniques.
The crystalline phase study performed for all the samples using X-ray powder diffraction (XRD) confirmed the formation of anatase TiO2.
Chemical composition of the prepared catalyst investigated by X-ray photo electron spectroscopy (XPS) affirmed the presence of constituent elements (Ti, O, Cu & B) on the catalyst surface.
The surface microstructure studied by field emission scanning electron microscopy (FE-SEM) revealed that the TiO2 particles having spherical shape with rough surface morphology.
The average particle size and surface area of the catalyst determined by high-resolution transmission electron microscopy (HRTEM) and Brunauer-Emmett-Teller (BET) surface area analyser, revealed that the codoped catalyst shows a high percentage of small particles of size 6.8 nm and a high surface area of 135.6 m2 / g, respectively.
The band edge absorption shift of the samples was determined by diffuse reflectance spectroscopy analysis (DRS) and the results exhibited that among all the codoped samples Copper 0.25 wt % and Boron 1 wt % (CBT1) catalyst shows a reduced band gap energy of 2.73 eV.
The characterization results supported the photocatalytic activity of the catalyst for the degradation of Lissamine Green B within 90 min at the optimum reaction parameters such as dopant concentration of Cu at 0.25 wt % & B at 1 wt %, pH =3, catalyst dosage 0.075 g/L and measurements.
