Embodiment 1

[0031] At room temperature, weigh aluminum isopropoxide (AIP) 1mmol (0.2042g), Co(NO 3 ) 2 . 6H 2 O 3mmol (0.8731g), Na 2 MoO 4 2H 2 O 1mmol (0.2420g), CS (NH 2 ) 2 10mmol (0.7612g) powder, and transfer all the powder to a dry reaction kettle with a capacity of 50 mL, and then use a pipette gun to measure 10mL octadecene, 5mL dodecylamine, and 3mL oleic acid to the reaction kettle , magnetically stirred for 2 h to obtain a solution.

[0032] The reaction kettle was tightened and transferred to an oven, the temperature was gradually raised to 180 °C, and kept at 180 °C for 24 h until the reaction was completed. After the reaction kettle was naturally cooled to room temperature, an appropriate amount of n-heptane and absolute ethanol were added to disperse, and the solid was separated by centrifugation. The solid was washed to obtain a black product, which was used for analysis and characterization after vacuum drying overnight in a vacuum oven.

Abstract

The invention discloses an Al-Co-Mo nanocrystal composite material, and a preparation method and application thereof, and belongs to the field of nanometers. The Al-Co-Mo nanocrystal composite material has a heterogeneous structure and good oxygen evolution performance, can efficiently catalyze an oxygen evolution reaction (OER) in a fuel cell. Further, a simple solid-liquid phase solvothermal method is used for controllably synthesizing the Al-Co-Mo nanocrystal such that the method is simple in process and good in process controllability , meets the standards of industrial production, is suitable for mass production, and has important guiding significance on the technical development of renewable energy.

Description

technical field [0001] The invention discloses an Al-Co-Mo nano crystal composite material, a preparation method and an application thereof, which belong to the field of nanometers. Background technique [0002] As the supply of fossil fuels dwindles, concerns about climate change, pollution and energy security related to them are growing. Therefore, the search for clean and renewable energy has become one of the biggest challenges facing the sustainable development of society. Central to this development is the need for advanced energy conversion systems such as water electrolysis, fuel cells, etc. In the process of designing fuel cells, improving the reaction efficiency of the oxygen evolution reaction (OER) has become the key to commercial applications. Durable electrocatalyst materials for oxygen evolution reaction, in which RuO 2 and IrO 2 to represent. But RuO 2 and IrO 2 Expensive, and in acidic media, RuO 2 and IrO 2 It will oxidize and dissolve, and has bec...
