摘要：
We report the in situ X-ray absorption investigations to study kinetic formation on NiO nanoparticles growth. The effects caused in the initial stage of particles growth by different heating rates are investigated. XAS results show that the particles disorder appears for high heating rates and growth process is faster for low heating rates. (c) 2007 Elsevier B.V. All rights reserved.
