▎ 摘　　要

NOVELTY - Preparing carbon nanotube/graphene nano-band heterojunction photoelectric device comprises (i) coating a single-wall carbon nanofiber dispersion liquid on an FTO conductive glass and drying, (ii) calcining, (iii) sequentially depositing titanium dioxide and transition metal on the single-walled carbon nanometre, (iv) performing single-clustered carbon nanometer melting under the assistance of hydrogen to obtain a graphene nano-belt/single-thick carbon nanomechanical intramolecular heterojunctions layer, and (v) depositing an indium tin oxide transparent electrode on the obtained graphene nanometal/single wall carbon nanomaterial intramolcular homojunction layer to obtain the carbon nano-tube/Graphene nanofibril/ single-thistrahydro-butyllium-tetraacetic acid photodetrolytic device. USE - The method used for preparing carbon nano tube/graphene nano-belt heterojunction photoelectric device, which is useful in electronic device. ADVANTAGE - The method can effectively control the melting degree of the single-wall carbon nano-tube, and can form a set of single wall carbon nano tube/graphene nano-band intramolecular heterojunction on a single wall. It can effectively improve the photo-generated current and photo generated voltage of the photoelectric device. Therefore, the sensitivity of the device can be greatly improved.
