Green Synthesis of Zinc Oxide with Hydrocharby lavandulifolia Extractand development of hydrogen storage capacity

In recent years, the environment has become seriously polluted as a result of the growth ofindustries. Polluted water sources have become a critical concern as a result of human activities,and different industrial operations have discharged organic contaminants that can causecarcinogenicity and toxicity in aquatic ecosystems [۱]. In light of this, water purification hasbeen regarded as an effective method of reducing pollution and water shortages. A number oftraditional water treatments, including adsorption [۲], ion exchange [۳], biological processes [۲],and membrane [۴], have been developed in recent years.The goal of this study is to produceenvironmentally friendly nanomaterials that have a high hydrogen storage capacity(۱). Theresearchers in this study used inexpensive material to produce hyrochar and a green solutionsynthesis combustion method to produce ZnO nanoparticles and nanocomposite using a Stachyslavandulifolia extract as the source material. Metal oxides such as ZnO are used to increasehydrogen storage capacity. Hydrochar and Hydrochar/ZnO nanocomposites have been confirmedvia XRD (X-ray diffraction), SEM(scanning electron microscopy, FT-IR (fourier transforminfrared. In terms of discharge capacity, ZnO, Hydrochar/ZnO display respective capacities of۲۲۰, ۵۰۰ mAh/g after ۴ cycles, respectively
