Solar photocatalytic degradation of phenol using nanosized ZnO and α-Fe2O3

This work focuses on the solar photocatalytic degradation of phenol using nanosized ZnO and α-Fe2O3 synthesized via precipitation route. The synthesized ZnO and α-Fe2O3 were characterized using XRD, UV/Vis and surface area analysis. α-Fe2O3 was found to exhibit better solar photocatalytic activity than ZnO under identical experimental conditions due to the larger surface area and low band gap of...

Characterization and optimization of poly (3-hexylthiophene-2, 5- diyl) (P3HT) and [6, 6] phenyl-C61-butyric acid methyl ester (PCBM) blends for optical absorption

Thin films were developed, characterized, and optimized for optical absorbance from blends of organic polymer poly (3-hexylthiophene-2, 5- diyl) (P3HT) and the fullerene derivative [6, 6] phenyl-C61-butyric acid methyl ester (PCBM). The materials of both pristine and blends were analyzed using X-ray diffraction spectroscopy and high resolution transmission electron microscopy for structural properties, and fourier...
