Two-Dimensional Bi₂WO₆ Nanosheets as a Robust Catalyst toward Photocyclization.

ABSTRACT: The present work describes the improved photocatalytic activity of cetyl trimethylammonium bromide (CTAB)-assisted Bi₂WO₆ (CBTH) toward the synthesis of bioactive benzazoles. X-ray diffraction analysis of CBTH suggests that crystal growth has occurred along the (200) plane, whereas field-emission scanning electron microscopy images confirm two-dimensional rose bud morphology and high-resolution transmission electron microscopy analysis suggests the formation of thin nanosheets possessing an orthorhombic structure. Temperature-programmed desorption of ammonia and Py-IR measurements indicate substantial acidity with the generation of Brønsted acid sites on the surface of CBTH. Raman spectra of CBTH also corroborate these observations with the formation of defects within
