A soft‐chemistry route to (impurity free) Ta 2 O 5 and HfO 2 nanopowders (see Figure) based upon a synthesis protocol that involves the reaction of metal alkoxides with benzyl alcohol is presented. The formation of HfO 2 proceeds via an unprecedented ether‐elimination process and extends the available non‐aqueous reaction methodologies in addition to the well‐known ester and alkyl halide eliminations.
