Three-Dimensional Cu Foam-Supported Single Crystalline Mesoporous Cu2O Nanothorn Arrays for Ultra-Highly Sensitive and Efficient Nonenzymatic Detection of Glucose

“…11 To improve the electronic conductivity of oxides, it is normal to construct composite materials by hybridizing with carbon-based materials [16][17][18] and noble metal nanoparticles. 19,20 Moreover, the intimate interface contact between the current collector and the highly electrocatalytic materials is crucial to enhance the electronic conductivity of electrodes and taking full advantage of electroactive substances.…”

One-pot synthesis of Mn3O4 nanoparticles decorated with nitrogen-doped reduced graphene oxide for sensitive nonenzymatic glucose sensing

“…As an alternative strategy, enormous interest has been paid on the employment of enzyme-free glucose sensors, which would provide convenience and advantages to avoid the drawbacks in enzyme electrode, and realize direct electro-catalytic oxidation of glucose at electrode surface. For example, several nanomaterials, such as Au-Ag particles/reduced graphene oxide [6], copper-cobalt nanostructures/ reduced graphene oxide [7], gold nanoparticles [8] and CuO nanowire [9], have been designed and employed as sensing materials for fabricating non-enzymatic glucose sensors, which overcome the disadvantages of enzymatic electrochemical glucose sensors to some extent. Graphene (GR), a novel carbon nanomaterial with a one-atom-thick planar sheet carbon structure arranged in a two dimensional honeycomb lattice, has attracted scientists' considerable interests because of its unique high surface area, rapid electron transport capability and thermal stability [10].…”

One-pot synthesis of hierarchically nanostructured Ni3S2 dendrites as active materials for supercapacitors

“…[7,8] Among the various nanostructures, many efforts have been devoted to the dendritic crystal growth patterns [9][10][11][12][13] that have a pronounced stem from which many side branches grow out and a hierarchical structure with primary, secondary, tertiary, and even high-order branches, because of their widespread potential applications in the new generation of advanced devices, such as electrochemical sensors, [12,14] lithium-ion batteries [15,16], and supercapacitors, [17] dependent on their rapid electrochemical reactions owing to the extremely large surface areas for ions transport. As one of the most promising energy storage devices, supercapacitors, also known as electrochemical capacitors, have attracted intensive research attention recently, due to their ultrahigh power density, fast charging/discharge rate and long lifespan.…”
