In the published paper entitled “Photocatalytic Oxidation of Trichloroethylene in Water Using a Porous Ball of Nano-ZnO and Nanoclay Composite” [1], we mistakenly used Laponite in our paper. The corrected name is Laponite (BYK Corporation’s products). So we are making some changes from Laponite to Laponite (BYK Corporation’s products) in our paper.
