Green Synthesis of CuO@PVAby lavandulifolia s Extract and developmentof hydrogen storage capacity

Today, due to the depletion of fossil fuel resources and the high importance of energy indeveloped and developing countries, scientists are looking for environmentally friendly, cheap,safe, and high energy density alternatives. Hydrogen, as a clean and environmentally friendlyenergy, has a high energy density, which promises to reduce or eliminate fossil fuels that pollutethe environment [۱]. Hydrogen, as a clean and environmentally friendly energy, has a highenergy density, which promises to reduce or eliminate fossil fuels that pollute the environment.Using hydrogen energy is really the most effective strategy to deal with the problems of energyexhaustion and the environmental pollution. Many new method and new topic for hydrogenenergyprocess chain and hydrogen economics, such as one-step approach towards hydrogenproduction, storage and transportations have been investigated [۲-۵]. In this work, PVA/CuOnanostructures organized with Stachys lavandulifolia extract have been used in hydrogen storagedue to the importance of hydrogen storage and green synthesis of nanoparticles. The synthesizedPVA/CuO nanostructures have been characterized by using XRD, FT-IR and their morphology,Morphology are investigated with SEM. The use of polymeric surfactants (PVA) increased thehydrogen storage capacity from ۱۱۰۰mAh/g (for synthesized without surfactant)to ۳۰۰۰ mAh/gand also improved the Columbic efficiency from ۵۵ to ۷۵%.
