NOVELTY - Preparing tellurene/graphene hybrid porous fiber having radial openings, comprises adding graphene oxide to tellurene pre-stripping dispersion liquid and performing ultrasound in a constant temperature water bath, centrifuging, collecting the bottom layer mixture, dispersing the bottom layer mixture in water, washing, concentrating, drying to obtain mixture of tellurene and graphene oxide; adding water to mixture of tellurene and graphene oxide and stirring the mixture to obtain mixture, sonicating the mixture by pulsed tip ultrasound, concentrating the mixed solution to obtain tellurene/graphene oxide mixed dispersion; peforming wet spinning using tellurene/graphene oxide mixed dispersion as spinning dope, glacial acetic acid as coagulation bath, and stepped spinning needle with a larger inner diameter to obtain wet tellurene/graphene oxide hybrid fiber; and washing the wet tellurene/graphene oxide hybrid fiber until the fiber is neutral, drying and reducing to obtain final product. USE - The tellurene/graphene hybrid porous fiber having radial openings is useful in flexible photodetectors, battery electrodes and photocatalysis (claimed). ADVANTAGE - The method: solves the defects of tellurene easy to stack with each other, poor dispersibility in water and lack of spinnability.
