Activated Charcoal Supported Cadmium Doped TiO₂ for Photocatalytic and Antibacterial Applications

Abstract

The photocatalytic activity was studied under UV light using AC-Cd/TiO 2 prepared via precipitation method and characterized by powder X-ray diffraction (XRD) , high resolution scanning electron micrographs (HR-SEM) with energy dispersive X-ray analysis (EDX), photoluminescence (PL) and Fourier transform Raman analysis (FT-RAMAN). The enhanced photo catalytic activity of the AC-Cd/TiO 2 is demonstrated through photodegradation of methylene blue under UV light radiation at 365 nm. The mechanism of photocatalytic effect of AC-Cd/TiO 2 Nano composite material has been discussed Further its antibacterial activity against two gram positive and two gram negative bacterial strain is studied.

Selective C−O Hydrogenolysis of Erythritol over Supported Rh‐ReOx Catalysts in the Aqueous Phase

“…Samples were scanned at 0.04° s −1 over the range 5≤2 θ ≤80°. Phase identification was achieved by using the JCPDS files as reference, that is, TiO 2 anatase structure (JCPDS 21–1272), ZrO 2 monoclinic phase (JCPDS 37–1484), metallic Rh (JCPDS 05‐0685), and metallic Re (JCPDS 05‐0702) . The mean crystallite sizes ( d M ) were estimated using the Scherrer equation from the half‐width of the XRD broadening peak in a diffraction pattern: d M =0.9 λ / β cos θ , in which λ is the X‐ray wavelength ( λ =1.54184 Å), θ is the Bragg angle, and is the line broadening at half‐maximum of the diffraction peak [rad].…”

Silicate Matrix with Implanted Peptide Self-Assemblies for Smart Sensor Electrodes and Coated Glass Systems

“…Recently, new class of solgel derived materials have been introduced with the mentioned rationalization on making porous matrix, which is compatible with the biomolecules [25][26][27][28][29][30][31][32][33][34]. Silicate matrix serve as reservoir for water, and it increases the ability to maintain the biological activity of enzymes, anti-bodies, and body fluid cells etc., [35][36][37][38][39]. These porous silicate matrices obtained by the low-temperature sol-gel method act as promising host matrix for the encapsulation of biomolecules [1,5].…”
