Sandwiched nanoarchitecture of reduced graphene oxide/ZnO nanorods/reduced graphene oxide on flexible PET substrate for supercapacitor

Synthesis of a ZnO nanorod/CVD graphene composite for simultaneous sensing of dihydroxybenzene isomers

“…Guo et al showed that ZnO nanorods as electrodes prevent aggregation of reduced graphene oxide sheets and help form a porous structure [40]. The combination of CVD graphene and ZnO nanorods offers synergistic effects and could yield an electrochemical sensor for the simultaneous detection of HQ, CC, and RC.…”

“…In this case, the black sample was distributed piecemeal onto white spots. Second, the graphene sheets with ZnO seeds layer were dipped into a Teflon autoclave filled with a 0.05 M zinc nitrate (Zn(NO 3 ) 2 ), 0.05 M hexamethylenetetramine (HMTA) and 2 mM polyethyleneimine (PEI) and heated at 100 C for 12 h [39,40]. After the autoclave cooled down naturally, the sample was removed and ultrasonically cleaned with ethanol and deionized water.…”

High-performance flexible solid-state supercapacitors based on MnO2-decorated nanocarbon electrodes

“…[9][10][11][12][13] As some of the major energy storage devices, supercapacitors have been widely used in high-power applications 14-17 because of their higher energy density than dielectric capacitors and higher power density, longer cycle life than batteries. [18][19][20][21][22][23] Nevertheless, the conventional supercapacitors use rigid packages which are not applicable in exible electronics.…”

Graphene nanosheets@ZnO nanorods as three-dimensional high efficient counter electrodes for dye sensitized solar cells

“…In this novel design, the aggregation of rGO sheets was efficiently reduced, leading to the increase of large specific surface area and outstanding electrical properties of graphene. 29,30 Furthermore, as an ionic compound, nano-structured ZnO is a promising candidate as an Based on the above discussion, one promising strategy for building hybrid nanostructure using the GNs with metal oxide ZnO nanorods to reduce the aggregation of GNs for energy device applications was proposed. In this work, taking into account the easy hydrothermal growth of ZnO nanorods on various substrates, especially on conducting FTO, a three-dimensional (3D) GNs@ZnO nanorod nanostructure as high efficient CE for DSSC was designed.…”
