The pathway for thermal decomposition of an oleic acid surfactant protecting Co and Ni nanocrystals is identified by probing the relevant molecular orbitals with x-ray absorption spectroscopy. The two steps observed previously in thermogravimetric measurements are identified with thermal desorption of entire molecules at ≈200 °C and dehydrogenation at ≈400 °C, which leaves a graphitic surface with alkane fragments underneath.
