英文摘要： Photoelectrochemical sensing based on semiconductor hybrid nanocomposite has been a new research focus in recent years. The project will combine the hybrid composite of metal oxide and the functioning of fullerene to obtain new hybrid photoelectric materials with visible light response. The new metal oxide/fullerene hybrid nanocomposite could be activated by visible light, and the photoelectrochemistry of nitric oxide (NO) radical would be realized on it. Firstly, metal oxide and fullerene will be combined by liquid phase method. The combination and photoelectric control mechanisms of the new hybrid nanocomposite will be explored based on its chemical composition, crystal structure and surface properties. Then, the photoelectrochemal sensing membrane will be built and optimized. The photoelectrochemical process of NO radical will be investigated on the resulting hybrid nanocomposite film. Finally, a new photoelectrochemical method for NO radical detection will be developed and applied in biological and medicine systems. The project can reveal the combination and photoelectric control mechanism between metal oxide and fullerene, obtain the photoinduced electron transfer and sensing mechanism for NO radical. One hand, The research will provide scientific fundation for the hybrid composite of nanomaterials and NO p
