Abstract

The invention discloses a one-step synthetic method for a carbon dot / poly(1,4-diphenyldiacetylene) hybrid photocatalysis material. According to the method, a 1,4-diphenyldiacetylene molecule functions as both monomer for formation of poly(1,4-diphenyldiacetylene) and a carbon source for formation of carbon dots; and the conductive carbon dot / poly(1,4-diphenyldiacetylene) hybrid photocatalysis material is prepared through three steps, i.e., mixing, sealing, and heat preservation and cooling. The method provided by the invention does not need a soft template and an initiator; a synthesized carbon dot / poly(1,4-diphenyldiacetylene) hybrid structure has more excellent visible light absorption capability and photocatalysis performance; and the method is free of complex purification, easier to control and beneficial for industrial large-scale production.

Description

technical field [0001] The invention belongs to the technical field of nanometer materials, and in particular relates to a method for synthesizing a carbon dot / poly-1,4-diphenylbutadiyne hybrid photocatalytic material in one step. Background technique [0002] Carbon dots are a new type of zero-dimensional carbon nanomaterials, which often contain hydrogen, oxygen, and nitrogen elements in addition to carbon elements. It not only has many excellent properties similar to traditional semiconductor quantum dots, but also can be used as an electron donor and acceptor to hybridize with other nanostructures or materials, thereby improving the overall performance of the material. An effective way to prepare carbon dots is to use the carbonization process of organic molecules, that is, at a suitable temperature, the hydrogen in the organic molecules reacts with oxygen in the molecules or provided by the outside to form water, and the original molecular structure is destroyed and rec...
