Investigation on Nanoarchitectonics of PJBAC/TiO2 for Photocatalytic and Antimicrobial Performance

The present work focuses on the synthesis of Prosopis juliflora bark activated carbon supported on TiO2 (PJBAC/TiO2) composite through the sol-gel method for the decolourization of Direct Brown 2 (DB2). The prepared composite was characterized by Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) analysis. The surface area and pore diameter were explored by the Brunauer−Emmett−Teller method (N2 adsorption/desorption). Furthermore, high-performance liquid chromatography (HPLC) and total organic carbon (TOC) analysis of the treated solution revealed a complete degradation of the dye molecule. The degradation efficiency of the prepared composite was analysed via batch equilibration studies. Maximum removal of DB2 (98
