چکیده

The United Nations General Assembly, in its declaration of the right to development (۱۹۸۶),declared energy in different forms an essential need to achieve the specified targets [۱]. Today,most energy needs are met through non-renewable sources [۲]. The use of non-renewableresources in addition to the environmental issues due to long-term use has reached a saturationlevel [۳]. Therefore, renewable sources for energy production at different levels are in demand.Among the renewable sources, hydrogen is one of the most attractive [۴]. At the same time, thisenergy carrier needs efficient and secure storage to have a bright future [۵].Polyvinyl alcohol(PVA) with high active sites is used as natural layered mineral supports. ZnO as a conductiveadditive was decorated on a PVA support to design an effective and environmentally friendlyactive material. Herein, an eco-friendly PVA/ZnO nanocomposite is fabricated via a green methodto equip developed hydrogen storage sites and to allow for quick charge transportation forhydrogen storage utilization. The hydrogen storage capacity of PVA/ZnO was ۳۰۰ mAhg−۱ at acurrent density of ۱ mA after ۵ cycles. It was also conceivable to increase the hydrogen sorptionability through ZnO in the nanocomposite

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
