| titleOfInvention | Multi-stage catalytic structure composite material for efficient water electrolysis hydrogen evolution and preparation method thereof |
| abstract | The invention discloses a multilevel structure composite material for efficient water electrolysis hydrogen evolution and a preparation method thereof, and the method comprises the following steps: pyrolyzing and carbonizing a powdery ZIF-67 material to obtain a Co @ NC material, and preparing Co (NO) in a mixed solution of the powdery ZIF-67 material 3 ) 2 ยท6H 2 The quantitative concentration of O is 40-60 mmol/L, and the quantitative concentration of 2-methylimidazole is 110-130 mmol/L; mixing the GO suspension with the Co @ NC suspension to obtain a mixed solution B, performing ultrasonic dispersion on the mixed solution B, and performing vacuum filtration, drying and grinding after uniform dispersion to obtain a powdery Co @ NC/GO composite material; fully oxidizing the Co @ NC/GO composite material to obtain Co 2 O 3 @ NC/GO composites; to Co 2 O 3 Phosphatizing and selenizing the @ NC/GO composite material to obtain the multi-stage structure composite material CoP-CoSe for efficient electrolytic water hydrogen evolution 2 @ NC/rGO. Generation of CoP-CoSe 2 The @ NC/rGO catalytic material has the advantages of uniform and controllable growth of CNTs, doping, multi-stage catalytic sites and the like, is high in catalytic hydrogen evolution performance, low in raw material cost and easy to realize large-scale preparation. |
