Photocatalytic Activity of Copper(II) Oxide Nanoparticles Synthesized Using Serratula Coronata L. Extract

Application of Silver-Loaded Composite Track-Etched Membranes for Photocatalytic Decomposition of Methylene Blue under Visible Light

“…According to the Beer–Lambert law, the concentration of MB is directly proportional to its absorbance. Thus, the degradation rate of MB was calculated based on its characteristic peak at 664 nm using the following equation [ 48 ]: where A 0 is the initial absorbance of MB solution at 664 nm before loading the catalyst, A is the absorbance at 664 nm at different time intervals, and C 0 is the concentration of feed solution.…”
