用正电子寿命谱研究氧化镍在Al_2O_3上的分散

The Dispersion of NiO On Al_2O_3 Studied By Position

用正电子湮没谱研究了用浸渍法制备的Al2O3担载NiO催化剂在不同烘烤温度、不同烘烤时间下NiO的分散情况。结果显示:在300℃左右烘烤2小时,NiO的分散情况最理想。

The diepersion of NiO on Al2O3 is studied by positron annihilation spectroscopy in this paper. The results showed that the diepersion of NiO on Al2O3 is best at 300℃ by baked with in 2 - 3h.
