摘要
探究了球磨参数(球磨速度、球磨时间和球料比)对石墨烯储氢性能的影响,并利用X射线衍射仪(XRD)对球磨后的石墨烯进行了晶体结构分析.结果表明:采用合适的球磨参数可改善石墨烯的储氢性能,球磨时间过长、球磨速度过快、球料比过大会导致石墨烯团聚.当球磨时间为12h,球料比为320∶1,球磨转速为330r/min时石墨烯储氢性能较优,储氢容量为2.49wt％.
Abstract
The effects of ball-milling parameters(ball-milling speed,ball-milling time,and ball-to-sample weight ratio)on the hydrogen storage properties of graphene were investigated,and the crystal structure analysis of ball-milled graphene was carried out using an X-ray diffractometer(XRD).The results showed that the hydrogen storage properties of graphene could be improved by using suitable ball-milling parameters,and too long ball-milling time,too fast ball-milling speed and too large a ball-to-sample weight ratio would lead to graphene agglomeration.When the ball-milling time was 12h,the ball-to-sample weight ratio was 320:1,and the ball-milling speed was 330r/min,the hydrogen storage performance of graphene was optimal,and the hydrogen storage capacity was 2.49wt％.
