Embodiment 1

[0033] Step 1): In a three-necked flask, add 80ml of water and heat to 75°C, then add 7.0g of styrene under vigorous stirring, and in another 10ml centrifuge tube, mix 0.024g of NaOH and 0.024g of NaOH 2 CO 3 Soluble in 5mL water and contain 0.03gK 2 S 2 o 8 Add 5ml of aqueous solution to the previous solution, pass nitrogen gas under the liquid surface for 10 minutes, and keep the temperature at 75°C for 12 hours to synthesize 300nm monodisperse polystyrene spheres. After the reaction is completed, return to room temperature and perform suction filtration to form a filter cake .

[0034] Step 2): 8.15g (0.0274mol) of Zn(NO 3 ) 2 ·6H 2 O, 6.75g (0.0822mol) of 2-methylimidazole and 0.045g (0.000274mol) FeCl 3 ·6H 2O was dissolved in 45ml of methanol solution. Then a piece of monolithic PS template was immersed in the above solution for 1 h, and further treated with vacuum degassing for 10 min, so that all the interstitial spaces between the 3D colloidal spheres were fi...

Abstract

The invention belongs to the technical field of catalysts and discloses an iron-nitrogen doped oxygen reduction carbon catalyst with ordered hierarchical holes and a preparation method of the iron-nitrogen doped oxygen reduction carbon catalyst with the ordered hierarchical holes. A hierarchical-hole three-dimensional ordered iron doped metal organic framework is formed by a 3D skeleton template,then a high-temperature calcining pyrolysis method is adopted to obtain the iron-nitrogen doped carbon catalyst with ordered hierarchical holes and an oxygen reduction function, and a promising application prospect in the field of metal-air cells, regenerative fuel cells and the like is achieved.

Description

technical field [0001] The invention relates to a preparation method of an iron-nitrogen doped oxygen reduction carbon catalyst with graded pores, has broad application prospects in the fields of metal-air batteries, renewable fuel batteries and the like, and belongs to the technical field of catalysts. Background technique [0002] In view of the serious shortage of traditional oil resources and the environmental pollution caused by it has become increasingly prominent, the development of new clean energy has become a national strategic demand. As a representative clean energy conversion device, the fuel cell known for its zero pollution and high energy conversion rate has been extensively studied all over the world. It can directly convert externally supplied fuel and oxidant into electrical energy through electrochemical reaction without direct combustion, so it is not limited by the Carnot cycle, the energy conversion efficiency can be achieved, and almost no nitrogen-co...
