Abstract

The invention belongs to the field of fuel cell hydrogen storage, and particularly relates to a copper nanowire material, a manufacturing method of the copper nanowire material and application of the copper nanowire material. The invention provides the manufacturing method of the copper nanowire material. The method comprises the following steps of mixing a copper nanowire, a pyridine compound and an organic solvent, and then washing and drying the obtained solid to obtain the copper nanowire material. The pyridine compound is selected from one or more types of pyridine, 4-aminopyridine, 4-methylaminopyridine, 4-dimethylaminopyridine and N, N-dipropyl pyridine-4-amine. The invention discloses the application of the copper nanowire material manufactured by the manufacturing method in electrochemical reduction of CO2. According to the copper nanowire material, the different pyridine compounds are modified on the copper nanowire, the catalytic effect is achieved, and CO2 can be efficiently reduced to prepare hydrocarbon.

Description

technical field [0001] The application belongs to the field of fuel cell hydrogen storage, and in particular relates to a copper nanowire material and its preparation method and application. Background technique [0002] With the rapid development of industry, the massive consumption of fossil fuels has exacerbated the energy crisis, and at the same time caused serious environmental problems, the most influential of which is the "greenhouse effect". The main cause of the "greenhouse effect" is the massive emission of carbon dioxide quantity. Therefore, reducing the production of carbon dioxide or converting carbon dioxide into useful raw materials is crucial for environmental protection. Among many treatment methods, due to the electrochemical reduction of CO 2 The method has the following advantages: the operating conditions are relatively simple (for example, it can be carried out at normal temperature and pressure), the process is easy to control (controlled by the elec...
