Abstract
A process for the photochemical dehydrogenation of alcohols comprises the steps of forming a suspension of semiconductor powder in the alcohol and photochemically activating the suspension in the presence of an oxidant with illumination having an energy at least equal to the band gap of the semiconductor powder. The process is one carried out at about ambient temperature and with gentle agitation. The semiconductor powder has the general formula A.sub.x B.sub.y C.sub.z where A is selected from Bi, Sn, Pt, Pd, Cu, Fe, W, V, Sb, Mo, Ru or Ag and mixtures thereof; B is Te, Sb, Ti, Cd, Mo, W or V and mixtures thereof; C is O or S; x equals 0.1 to 5; y equals 1 to 3; and z is a number necessary to satisfy the other elements, and is optionally metallized by an element selected from Pt, Pd, Cu or Ag.
