The coupled WO3-AgBr nanocatalyst, part II: Synthesis, characterization, and the boosted photocatalytic activity towards metronidazole in an aqueous solution

“…Commonly, the crystallite size, induced strain, instrumental parameters, and crystal defects have been counted as the influencing factors on the diffraction peak broadening. The W-H model gives the Scherer model in a particular strain factor η = zero case [ [84] , [85] , [86] ].…”
