Effect of combined chemical and electrochemical reduction of graphene oxide on morphology and structure of electrodeposited ZnO

Effect of AZO film as seeding substrate on the electrodeposition and properties of Al-doped ZnO nanorod arrays

“…The electrochemical deposition technique has become an increasingly active research area in recent years due to its low cost, mild conditions and accurate process control [1]. It is well known that electrodeposition can be applied as nanostructuring technology to a wide range of materials including semiconductor oxides (such as ZnO nanowires) [12,13], graphene materials [14,15], metals (such as Cu nanowires) [16] and conducting polymers (such as poly(o-phenylene diamine)) [17].…”

ZnO and reduced graphene oxide electrodes for all-in-one supercapacitor devices

“…25,26 Additionally, the ZnO particles acted as spacers to effectively separate graphene sheets that in turn affected the final performance of the materials composed of rGO. 27 Meanwhile, Cembrero et al 28 reported about a 43% increase in the conductivity of rGO/ZnO hybrid nanomaterials by the coupled chemical and electrochemical reduction method with a 5 mg L −1 rGO content in ZnO compared to pure ZnO.…”

“…The chemical reduction method to synthesize rGO is the most widely preferred and low-cost method to produce graphene in a large quantity. Besides, hydrazine, 29 ascorbic acid, 30 glucose 31 and ethylene glycol 32 have generally been used in chemical reduction methods as reagents to hybridize graphene with inorganic nanoparticles, such as Ag, Au, SnO 2 , TiO 2 , ZnO 25,28,33,34 and polymers. 35,36 Among them, ascorbic acid is a newly reported reducing reagent for GO and inorganic metal/metal–oxide doped GO.…”

Effect of grain-size on the ethanol vapor sensing properties of room-temperature sputtered ZnO thin films

“…Nano-structuring of ZnO can be accomplished by various growth techniques including pulsed laser deposition [16], Radio Frequency (RF) magnetron sputtering [12,17] and electrochemical deposition [18,19]. Amongst all available ZnO nanostructures suitable for gas sensitivity, thin films are preferable since they can be easily integrated to microelectronic technology and RF sputtering technique has been indicated as a viable method of preparing metal oxide films for ethanol sensing applications due to its easy control over the preferred crystalline orientation, growth at relatively low temperature, good interfacial adhesion to the substrate, and the high packing density of the grown film [20].…”
