Abstract Carbon materials were prepared by plasma chemical vapor deposition at different pressures without catalyst, and the structure and hydrogen storage characteristics of milled and unmilled samples of the materials were evaluated. Using this approach, we were able to fabricate graphite microcrystals with a crystallite size of several nanometers, and the crystallite size and surface area could be controlled by changing the pressure during plasma chemical vapor deposition. The hydrogen storage capacity of the unmilled materials was 0.3 wt%, but milling increased this value to 1.0 wt% by reducing the crystallite size and increasing the crystallite surface area.

通过等离子体化学气相沉积制造的机械研磨碳材料的储氢

摘要 在不加催化剂的条件下，采用等离子体化学气相沉积法在不同压力下制备碳材料，并对材料的研磨和未研磨样品的结构和储氢特性进行了评价。使用这种方法，我们能够制造出微晶尺寸为几纳米的石墨微晶，并且可以通过改变等离子体化学气相沉积过程中的压力来控制微晶尺寸和表面积。未研磨材料的储氢容量为 0.3 重量％，但研磨通过减小微晶尺寸和增加微晶表面积使该值增加到 1.0 重量％。
