Abstract

The invention discloses a preparation method of a carbon nanotube composite catalytic membrane. The preparation method comprises the following steps: providing a carbon nanotube membrane; providing aprecursor solution, wherein the precursor solution contains ferric nitrate, nickel chloride and molybdenum pentachloride; arranging the precursor solution on the carbon nanotube film, and drying the precursor solution to obtain a precursor film, and forming a plurality of holes in the precursor film at intervals; finally, annealing the precursor film with the plurality of holes, and applying sulfur powder thereto in the annealing process. The invention also relates to the carbon nanotube composite catalytic membrane prepared by the preparation method of the carbon nanotube composite catalyticmembrane.

Description

technical field [0001] The invention relates to a carbon nanotube composite catalytic membrane and a preparation method thereof. Background technique [0002] Molecular Hydrogen (H 2 ) is a sustainable energy source that can replace fossil fuels. The molecular hydrogen can be obtained by splitting water. During water splitting, the hydrogen evolution reaction (HER) occurs at the cathode and the oxygen evolution reaction (OER) occurs at the anode. Electrocatalysts can reduce the overpotential in electrochemical reactions and promote the occurrence of the hydrogen evolution reaction and oxygen evolution reaction. The electrocatalysts commonly used noble metals, for example, Pt / C is usually used for hydrogen evolution reaction, IrO 2 or RuO 2 Usually used for oxygen evolution reaction. However, the application of these noble metals as electrocatalysts will be greatly limited due to high cost and scarcity. Contents of the invention [0003] In view of this, it is indeed...
