Abstract

The invention discloses a preparation method and application of an iron-nickel-doped tantalum nitride carbon nano-film integrated electrode. The method comprises the following steps: synthesizing a tantalum oxide nano-film, taking the tantalum oxide nano-film as a carrier, loading ferric hydroxide and nickel hydroxide through a hydrothermal method, carrying out a nitridation reaction on the synthesized composite material through a chemical vapor deposition (CVD) method, and naturally cooling to room temperature to prepare the iron-nickel-doped tantalum nitride carbon nano-film integrated electrode. The preparation process is simple, and the preparation of the iron-nickel-doped tantalum nitride carbon nano-film integrated electrode can be completed through a CVD furnace without a special pressure environment. The prepared iron-nickel-doped tantalum nitride carbon nano-film integrated electrode has electro-catalytic hydrogen evolution and oxygen evolution performances at the same time.

Description

technical field [0001] The invention relates to a preparation method of an iron-nickel-doped tantalum nitride carbon nano-film integrated electrode and its application in the field of electrochemistry, belonging to the fields of new material preparation and electrochemistry. Background technique [0002] Energy is the foundation of human survival and development, and directly affects the economic lifeline of each country and the development direction of all mankind. Currently, the growing conflict between increasing energy demand and environmental degradation caused by the burning of fossil fuels has sparked enormous interest in finding efficient, clean and renewable alternative energy sources. [0003] As an abundant carbon-free fuel, hydrogen has an ultra-high calorific value and zero carbon dioxide emissions, and is considered to be an ideal choice to replace carbon-based fuels in the future. Hydrogen energy is an efficient clean energy source. The total energy of hydrog...
