Preparation method of novel nano carbon material and electrocatalytic hydrogen production application of novel nano carbon material

Abstract

The invention relates to a preparation method of a novel nano carbon material and an electrocatalytic hydrogen production application of the novel nano carbon material. The preparation method comprises the following steps that (1), a second or multiple metal synthesized bimetal or multiple metal base ZIFs material is introduced into a monometal ZIFs skeleton structure at a special temperature; (2), the ZIFs material is carbonized in an inert atmosphere at a temperature higher than a decomposition temperature of an organic ligand of the ZIFs material to obtain a carbon material; (3), the carbon material is modified on the surface of an electrode and linear sweep voltammetry response is performed in an electrolyte solution with certain PH (potential of hydrogen) and certain concentration; (4), alternating current impedance is performed in the electrolyte solution with the certain PH and the certain concentration; (5), cyclic voltammetry response is performed in an alkaline solution and then linear sweep voltammetry response is measured. The preparation method has the benefits that a raw metal salt material is wide in range, so that the cost is saved and industrial production and preparation is facilitated; the method has important significances and wide application prospects in the aspect of the prepared nano carbon material, in an application extending the ZIFs material and in the field of electrocatalysis.

Description

technical field [0001] The invention relates to the preparation and application of a carbon nanometer material, in particular to a preparation method of a novel nanometer carbon material and its electrocatalytic hydrogen production application. Background technique [0002] Since the 20th century, the global human society has developed at an alarming rate. With the increase of population and the improvement of people's living standards, human demand for energy is also increasing. People's heavy dependence on traditional non-renewable fossil energy has led to serious environmental pollution problems facing the development of today's society. Therefore, research and exploration of various clean and renewable energy sources have attracted more and more attention from countries all over the world. As a secondary energy source, hydrogen energy not only has the advantages of being clean, non-polluting, efficient, storable, easy to transport, and rich in resources, but also the com...
