An Efficient Green Synthesis Method for the Synthesis of Silver Nanoparticles Using the Extraction of Catha Edulis Leaves

The synthesis of nanoparticles using plant extracts has received great attentions during the last two decades. That is plausibly due to its simple, rapid, toxic-free, and efficient reactions. In this study, a unique green method for preparing silver nanoparticles (Ag NPs) using the extract of Qat (or Khat) leaves is reported. The method is cheap, easy and has a potential for mass production of nanoparticles. Qat is a fast growing plant used mostly as stimulant in Yemen and South African countries and contains dozens of phytochemicals in its leaves
