Embodiment

[0136] Using a commercially available spin coater (Laurell Tech), the catalyst (Fe(III) / TS / DBS or / PS was spin-coated from a 10% (w / w) Fe(III) TS / ethanol solution at 1000 rpm) to A thin film of 1μm is formed on a quartz plate (3mm thick, 4×10cm). Then, in a conventional heating furnace at 60-80℃, the catalyst film is annealed for 5 minutes until the film color becomes dark yellow, indicating that the ethanol solvent has evaporated .

[0137] Commercially available thermal CVD system (Atomate) is used to enable the software to control gas flow, furnace temperature and deposition time for chemical vapor deposition. Rinse the system with argon (Ar, 150ml / min) for 30 minutes, and then use Ar (200ml / min) and H 2 (20ml / min) The temperature of the furnace is increased under the air flow to 500°C. Then, the furnace temperature is maintained at 500° C. for 10 minutes to reduce the iron (III) into iron nanoparticles. Then increase the temperature to 800 ℃, and then use the gas flow rate Ar ...

Abstract

The present invention relates to nanostructured composites comprising a nanotube network which is at least partially embedded within a carbon layer. The present invention particularly relates to conducting nanostructured composites for use in the fields of energy conversion, energy storage and also the biomedical field. The present invention also relates to a process via CVD of carbon onto a catalyst layer on a substrate.

Description

Technical field [0001] The present invention relates to nanostructured composites, especially conductive nanostructured composites used in the fields of energy conversion, energy storage and biomedicine. The invention also relates to a method for preparing the nanostructured composite. Background technique [0002] With the reduction of non-renewable fuel energy, there is a great need for more effective energy conversion and storage methods. Common energy storage devices such as batteries and capacitors rely on electrodes to work. [0003] The electrode of a photochemical battery requires a large surface area to allow the charge to efficiently migrate into the electrolyte. Electrodes in devices used for charge storage also require large surface areas and high conductivity. [0004] Bioelectrodes are used to deliver electric charges to living organisms, or to sense electrical pulses in or on living organisms. Common bioelectrodes include pacemaker electrodes and electrocardiogram ...
