Volume 3, Issue 3 , July 2018, , Pages 273-278

https://doi.org/10.22090/jwent.2018.03.008

Abstract
  ZnO/bentonite photocatalyst was synthesized using different methods, including: precipitation, liquid-state ion exchange (LSIE) and solid-state Ion exchange (SSIE) methods. In most studies done so far, LSIE and precipitation method have been used to prepare composites. The SSIE is a new method. The purpose ...  Read More
