The design and development of novel photocatalysts for treating toxic substances such as industrial waste, dyes, pesticides, and pharmaceutical wastes remain a challenging task even today. To this end, a biowaste pistachio-shell-derived activated carbon (AC) loaded TiO2 (/AC TiO2) nanocomposite was fabricated and effectively utilized towards the photocatalytic degradation of Malachite Green dye (MG) under UV-A light. The synthesized materials were characterized for their structural and surface morphology features through various spectroscopic and microscopic techniques, including field emission scanning electron microscope (FE-SEM) along with Energy Dispersive X-ray dispersive spectroscopy (EDX), diffuse reflectance spectra (DRS), X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR). The presence of AC influences the photocatalytic activity of TIO2/AC nanocomposite towards MG 100 minutes degradation. These results demonstrate that TIO2/AC nanocomposite could be effectively used as an ecofriendly, cost-effective, stable, and highly efficient photo- catalyst.
