摘要:

在能源危機和環境污染的雙重壓力下，發展氫能等綠色可再生能源已成為滿足未來全球能源需求的優先選擇。安全、高效的儲氫技術是氫能應用的主要瓶頸之一。硼氫化鈉（NaBH4）的理論儲氫密度高、生產成本較低，是一種頗具應用前景的固態儲氫材料。利用NaBH4水解反應而發展起來的可控制/儲氫技術具有典型的“制—儲—運”一體化特征，為突破目前傳統制/儲氫技術難題提供了解決方案，在車載、便攜式氫源系統等領域展現出良好的應用前景。然而，NaBH4催化水解制氫存在水解動力學性能差、催化劑成本高、水解產物再生困難等問題。介紹了NaBH4的理化性質及水解制氫的機理，綜述了NaBH4水解制氫催化劑、副產物再生回收的研究現狀及其水解制氫裝置的研制進展，展望了NaBH4水解制氫的發展方向。

Abstract:

With the energy crisis and environment pollution becoming increasingly serious，the development of green and renewable energy，such as hydrogen energy，has become a priority for meeting future global energy needs．A pivotal challenge in the application of hydrogen energy lies in the establishment of safe and efficient hydrogen storage technologies．Sodium borohydride (NaBH4)，characterized by its high theoretical hydrogen storage capacity and relatively low production cost，emerges as a promising solid�瞫tate hydrogen storage material．The controllable hydrogen generation and storage technology，realized through the hydrolysis of NaBH4，offers a compelling solution with its ‘production-storage-transport’ integrated approach．This technology holds the promise of surmounting existing hurdles in traditional hydrogen generation and storage methods，exhibiting particularly strong potential in on�瞓oard and portable hydrogen supply systems However，the catalytic hydrolysis of NaBH4 for hydrogen generation faces certain challenges，including sluggish hydrolysis kinetics，elevated catalyst expenses and complexities in regenerating hydrolysis byproducts．In this review，we introduce the physicochemical properties of NaBH4 and discuss the mechanistic aspects of hydrolysis for hydrogen generation．Furthermore，we provide a comprehensive overview of ongoing research in catalyst development for NaBH4 hydrolysis，strategies for byproduct recycling and advancements in hydrolysis equipment．Finally，the challenges and future directions for the evolution of NaBH4 hydrolysis as a pivotal method for hydrogen generation are pointed out as well．
