Ammonia　borane　is　considered　as　a　potential　solid　hydrogen　storage　material　due　to　its　high　hydrogen　content　of　19.6%,　high　stability,　non-　toxicity　and　high　solubility　in　ordinary　solvents.　The　catalysts　with　micro-nano　fibers　as　carriers　prepared　by　electrospinning　technology　can　effectively　overcome　the　shortcomings　of　traditional　nano-metal　catalysts　such　as　agglomeration,　loss,　pollution　and　difficult　recovery.　This　paper　focuses　on　the　preparation　of　nano-catalysts　for　hydrolysis　of　ammonia　borane　from　three　aspects　of　electrospinning　technology,　the　classification　of　nanofibers　and　catalysts.　Regarding　nanofibers,　the　steps　and　key　technical　points　for　the　preparation　of　different　kinds　of　fibers　by　electrospinning　were　discussed　in　detail.　As　for　the　catalysts,　the　preparation　processes　of　precious　metals　and　non-noble　metal　catalysts　as　well　as　their　advantages　were　reviewed,　and　the　selection　principles　of　catalyst　particles　and　carriers　was　summarized.　Finally,　the　methods　of　upgrading　and　optimizing　both　the　process　and　the　equipment,　rational　design　of　the　catalytic　particles　and　the　carriers,　and　the＇threestep＇　chemical　reaction　are　put　forward　respectively　to　solve　the　problems　of　low　electrospinning　efficiency,　poor　catalytic　performance　and　difficult　for　the　regeneration　of　ammonia　borane.　©　2019,　Chemical　Industry　Press.　All　right　reserved.
