Embodiment 1
[0035] 0.80g potassium hexacyanocobaltate K 3 Co(CN) 6 Dissolve in 50mL deionized water, add 2.1g EO 20 PO 70 EO 20 (Pluronic P123), stirred until completely dissolved; then added dropwise until 4.0g of ZnCl was dissolved 2 In 10ml of aqueous solution, stirred and reacted at 75°C for 2 hours, then obtained a solid after suction filtration and vacuum drying; mixed the obtained solid with 11.42g of tetra-n-butylammonium bromide, ball milled with tetrahydrofuran as a solvent for 24 hours, and distilled off the solvent and drying to obtain a two-component bimetallic catalyst.
[0036] The elemental analysis results were: Co: 1.19, Zn: 2.59.
Embodiment 2
[0038] Dissolve 2.0g potassium bromide pentacyanocobaltate in 8.0ml deionized water, add 2.1g EO 20 PO 70 EO 20 , stirred until completely dissolved; then added dropwise until 30.0g of ZnCl was dissolved 2 In 100ml of aqueous solution, stirred and reacted at 75°C for 2 hours, then obtained a solid after suction filtration and vacuum drying; mixed the obtained solid with 12.50g of tetra-n-butylammonium chloride, ball milled with tetrahydrofuran for 24 hours, and distilled off the solvent and drying to obtain a two-component bimetallic catalyst.
[0039] The elemental analysis results were: Co: 1.09, Zn: 2.39.
Embodiment 3
[0041] According to embodiment 1, adopt 15.0g zinc nitrate, change tetra-n-butylammonium bromide into 0.94g dedecyltrimethylammonium bromide simultaneously.
[0042] The elemental analysis results were: Co: 6.99, Zn: 15.30.
