Abstract

The invention discloses a preparation method of a flexible Ag-Pd / ZrO2@carbon fiber cloth catalyst, which comprises the following steps: dissolving carbon fiber cloth in an acetone solution, carrying out ultrasonic cleaning, sequentially carrying out ultrasonic cleaning with deionized water and alcohol, drying, putting the carbon fiber cloth in a ZrOCl2. 8H2O, PdCl2 and AgCl2 mixed solution, carrying out ultrasonic treatment, and dropwisely adding ammonia water into an obtained mixed solution until the pH value is 8-14, introducing the mixed solution into a reaction kettle for hydrothermal reaction, at last washing a reaction solution with deionized water, and drying to obtain the flexible Ag-Pd / ZrO2@carbon fiber cloth catalyst. The flexible Ag-Pd / ZrO2@carbon fiber cloth catalyst prepared by the method has the advantages that the components, the nanoparticle size and the crystallization degree can be regulated and controlled, the binding force between the loaded nanoparticles and a flexible carrier is strong, and the stability is high; and the cost of the catalyst is effectively reduced under the condition of keeping high catalytic performance. And meanwhile, excellent conductivityis achieved.

Description

technical field [0001] The invention belongs to the technical field of preparation of catalytic materials, in particular to a flexible Ag-Pd / ZrO 2 Preparation method of @carbon fiber cloth catalyst. Background technique [0002] In recent years, flexible electronic products have attracted widespread attention due to their light, portable, and foldable properties, which has led to rapid development of flexible power devices and are widely used in new energy fields such as supercapacitors, rechargeable batteries, and solar cells. [0003] The essence of flexible fuel cell is a kind of flexible catalytic conversion device, and flexible catalyst is an indispensable important material for it. This kind of catalyst will break through the limitations of the original supported catalysts limited to hard and brittle supports such as metals and oxides. At present, the preparation methods of flexible catalysts mainly include dispersing and bonding the active powder on the flexible sub...
