Electrodeposition of anionic, cationic and nonionic surfactants and gold nanoparticles onto glassy carbon electrode for catechol detection
Three surfactants were selected to modify glassy carbon electrode including sodiumdodecylbenzenesulfonate, Tween 80 and cetyltrimethylammonium bromide. The obtained nano-Au/surfactant/GCEs were characterized with scanning electron microscopy and electrochemicaltechniques. Electrochemical behavior of catechol at the nano-Au/surfactant/GCE was thoroughlyinvestigated for mo...
متن کاملFacile fabrication of hierarchical ZnCo2O4/NiO core/shell nanowire arrays with improved lithium-ion battery performance.
We report a facile and controllable strategy for the fabrication of three-dimensional (3D) ZnCo2O4/NiO core/shell nanowire arrays (ZCO/NiO NWs) on nickel (Ni) foam substrates by a simple, cost-effective, two-step, solution-based method. Ultra-thin NiO nanosheets are revealed to grow uniformly on the porous ZnCo2O4 nanowires with many interparticle mesopores, resulting in the formation of 3D cor...
متن کاملHigh-performance supercapacitor electrodes based on hierarchical Ti@MnO(2) nanowire arrays.
Ti nanowire arrays (NAs) prepared by a facile and template-free hydrothermal method were used as three-dimensional (3D) current collectors for the electrodeposition of MnO2. The resulting Ti@MnO2 NAs exhibit remarkable electrochemical behavior with high specific capacitance, good rate performance and desired cycling stability.
متن کاملFacile fabrication of freestanding three-dimensional composites for supercapacitors.
A facile and highly efficient method for the fabrication of free-standing three-dimensional (3D) composites with different morphologies was designed by the combination of the electrospinning method and hydrothermal reaction. The controlled hierarchical nanoarrays showed excellent electrochemical performance for their potential use as supercapacitor electrodes.
متن کاملSilicon/hematite core/shell nanowire array decorated with gold nanoparticles for unbiased solar water oxidation.
We report the facile fabrication of three-dimensional (3D) silicon/hematite core/shell nanowire arrays decorated with gold nanoparticles (AuNPs) and their potential application for sunlight-driven solar water splitting. The hematite and AuNPs respectively play crucial catalytic and plasmonic photosensitization roles, while silicon absorbs visible light and generates high photocurrent. Under sim...
