Catalytic chemical vapour deposition has become a method of choice to produce carbon nanotubes (CNT), particularly for the synthesis of aligned nanotube forests. But a thorough understanding of the mechanisms for CNT nucleation, growth and alignment is still missing. In situ and time resolved experiments allowing to study these processes in real conditions are required. We have developed a specific reactor and furnace to perform such experiments using X‐ray diffraction (XRD). Experiments were performed at synchrotron SOLEIL. XRD patterns were recorded as a function of time, during nucleation and growth. We present here our first results, discussing the interest of the XRD method with respect to other existing in situ methods.
