| The main problems of sustainable development in the world today are energy and environmental issues.In various new energy strategies,hydrogen is used as the main carrier.By building energy infrastructure and using hydrogen energy for different purposes,energy safety and cleanliness can be achieved.For this reason,the effective storage and production of hydrogen is a key element of hydrogen energy.At present,the most promising hydrogen production method is electrolysis of water to produce hydrogen.However,due to the problems of expensive and limited reserves of traditional platinum-based precious metal electrode catalysts,the application of electrolysis water hydrogen production technology is severely limited.Therefore,the focus of current research is the development of low-cost,large-scale synthesis of hydrogen evolution catalysts to make the water decomposition process more energy-efficient and economical.In this paper,the molybdenum selenide,tungsten selenide nanosheet heterostructure was synthesized by electrospinning and chemical vapor deposition using POM as the substrate,which greatly improved the specific surface area and conductivity of the material and increased the active sites.Exposure increases the catalytic activity.It not only synthesizes a cathode material with a highly efficient hydrogen evolution catalytic effect,but also explores the influence of the morphology,structure,different growth dimensions and size of the material on the catalytic hydrogen evolution reaction effect,and explores various materials.The relationship between nature and hydrogen evolution catalytic activity.In this paper,by combining the unique structure with new technical means,cobalt-molybdenum carbides and transition metal chalcogenide heterojunction nanosheet materials are loaded on the electrospun nano-carbon fibers,and the synthesized materials have excellent hydrogen evolution catalytic effect.And the preparation cost is low,the preparation method is simple,and it can be prepared in a large scale,which provides a direction for the research on the industrial preparation of the hydrogen evolution reaction catalyst. |
