Volume 5, Issue 4 , October 2020, , Pages 358-368

https://doi.org/10.22090/jwent.2020.04.006

Abstract
  Homogenous catalysis which the catalyst operates in the same phase as the reactants is definitely efficient in catalysis processes while it suffers from the impossibility or inconvenience of the removal of the catalyst from the reaction media. In this research, In2S3 nanoparticles were synthesized by ...  Read More
