Hydrogen Storage for Energy Application

Facile Synthesis of Cu2O /Cu/RGO Nanocomposite

“…To attenuate such kind of problems using metallic powder (Mg, Al, Fe and Zn) in aqueous acidic medium is another option [18,19,20,21]. In which a redox couple is developed between GO and oxidizing metal species and during the process produced electrons reduces the GO [22]. More importantly, in this metal assisted reduction process generated gaseous hydrogen molecule also efficiently reduces the GO [18].…”

Improved Reduction of Graphene Oxide

“…The high thermal conductivity ( 3000 Wm -1 K -1 ), high electron mobility (15000 cm 2 V -1 s -1 ), and high specific surface area of graphene nanosheet are also few amasing characteristics of material [2,3,4]. As an electronic material, graphene represents a new playground for electrons in 2, 1, and 0 dimensions where the rules are changed due to its linear band structure [5,6,7]. When graphene is incorporated with metal or metal oxides nanoparticles (NPs) its peculiar properties manifest as remarkable improvements in the host material [8,9,10].…”

“…GO exhibits strong covalent attachment with some oxygen functionalities such as hydroxyls, carbonyl, phenolic and epoxides [18,19]. Although, CVD grown and mechanically synthesized graphene (pristine graphene by scotch tape method) contains single or few layers of sp 2 structures, but for practical applications chemically exfoliated graphene is more attainable due to its higher yield [7]. However, adherence of oxygen containg groups bring the poor electrical conductivity of GO and it is highly desirable their reduction in efficient manner for electrical and electronics applications [7,18].…”

A Review of a Stand-Alone Hydrogen System Application for Private Houses in Greece and the Use of Phase Change Materials in Their Building Construction

“…At applied pressure, hydrogen will bond with porous carbon materials such as nano-tubes. [20,21] Hydrogen can be a good energy storing solution, but the technology still has to be developed for the architectural practice, so there are no fully hydrogen powered projects built on such a public building scale.…”
