The RAPET reaction at 700 °C, of different alkoxides (Ti, V, and Si) led to three different nanocomposites. Carbon is the element common to all three structures. Carbon was found as the core in the decomposition of TEOS, as the shell in the decomposition of VO(OEt) 3 and embedded in, or mixed completely with, TiO 2 in the decomposition of Ti(O i Pr) 4 . This novel method using only metallic alkoxide precursor, in the absence of catalyst, leads in a one‐step process to core‐shell structures.
