We report on a simple strategy for the direct synthesis of a thin film comprising interconnected NiO nanoparticles deposited on both sides of a graphene sheet via cathodic deposition. For the co-electrodeposition, graphene oxide (GO) is treated with water-soluble cationic poly(ethyleneimine) (PEI) which acts as a stabilizer and trapping agent to form complexes of GO and Ni2+. The positively cha...

Fe(2+) cations in FeCl(2) or FeSO(4) were oxidized by graphene oxide, leading to an in situ deposition of Fe(3)O(4) nanoparticles onto the self-reduced graphene oxide (rGO) sheets. The resultant Fe(3)O(4)/rGO sheets were demonstrated to possess interesting magnetic and electrochemical properties attractive for a large variety of potential applications.

The transfer of chemical vapor deposition (CVD)-grown graphene is the prerequisite for many applications. Herein, we introduce a simple and eco-friendly electrochemical technique to transfer graphene using agarose gel as the solid electrolyte and a mechanical support layer for graphene sheets. This transfer technique will be a perfect candidate for the industrial applications of graphene.

In this communication, we develop a simple pathway to prepare SERS-active substrates with Au nanoparticles (NPs) by an electrochemical strategy of deposition-dissolution cycles (DDCs). The prepared SERS-active substrates demonstrate large Raman scattering enhancement for Rhodamine 6G (R6G) with a detection limit of 2 × 10(-12) M and an enhancement factor of 5.8 × 10(7).

Nanostructured network-like MnO2-NiO composite electrodes were electrodeposited onto stainless steel substrates via different electrodeposition modes, such as chronopotentiometry, chronoamperometry, and cyclic voltammetry, and then subjected to heat treatment at 300°C for metal oxide conversion. X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy...

The electrodeposition of germanium at elevated temperatures up to 180 °C and pressures was studied from the ionic liquids 1-butyl-1-methylpyrrolidinium dicyanamide and 1-butyl-1-methylpyrrolidinium bis(trifluoromethylsulfonyl)imide containing [GeCl4(BuIm)2] (where BuIm = 1-butylimidazole) or GeCl4. Cyclic voltammetry (CV), electrochemical quartz crystal microbalance (EQCM), rotating ring-disk e...

Cu2O nanowires, mainly consisting of (100) and (200) polycrystalline structures with a length of 4 mum are prepared by electrochemical deposition using a porous alumina template. It is found that the optimized electrochemical conditions to prepare Cu2O nanowires are different from those for the formation of a bulk thin Cu2O layer since different pH values are found between the tip of the pores ...
