Abstract

The invention discloses a rodlike bismuth sulfide hollow nanoscale balloon and a preparation method thereof. The preparation method of the rodlike bismuth sulfide hollow nanoscale balloon comprises dispersing monodispersed hierarchical porous structured ZnS nanoscale balloons and thiourea into alcohol solution, stirring and heat-preserving the mixture at 80-130 DEG C for 10 min, then rapidly filling in bismuth salt fully dissolved inside alcohol solution for exposed reaction for 10-30 min, naturally cooling down to room temperature, performing centrifugal washing to obtain the target product of the rodlike Bi2S3 hollow nanoscale balloon. The preparation method for the first time achieves synthesis of the rodlike Bi2S3 hollow nanoscale balloon in solution phase in an exposed system and accordingly is simple in synthesizing method and mild in reaction conditions; the prepared rodlike Bi2S3 hollow nanoscale balloon is uniform in morphology, low in product cost and applicable scaled industrial production.

Description

technical field [0001] The invention belongs to the technical field of nanomaterial preparation, in particular to a rod-shaped Bi 2 S 3 Hollow nanosphere and its preparation method. Background technique [0002] Currently, tumor treatment methods mainly include surgery, radiotherapy and chemotherapy. Traditional operative therapy can cause very big trauma and misery to the patient because of generally will carry out thoracotomy, laparotomy etc. surgical operation to the patient. Radiotherapy and chemotherapy often cause damage to organs and tissues in other parts of the human body because of their large side effects. [0003] Carry out early imaging of tumors at the same time or start targeted treatment within a short period of time, effectively grasp the timing of tumor treatment, reduce the risk of surgical treatment, and avoid accidents such as exacerbation of the disease, incomplete tumor removal, metastasis, and recurrence due to time delay happened. In recent year...
