Abstract
The temperature-programmed-activation (TPA) of CuSi, CuSi(H) (prepared using CuCl and CuCl . 2H2O, respectively), and CuSi copromoted with z inc and tin have been investigated. The main effect of promotion was t o increase the activation temperature suggesting that dnc may inhibit the transfer of chlorine from CuCl to surface silicon atoms. The sampl e prepared using hydrated cuprous chloride initially exhibited reduced activity for the Direct Reaction relative to CuSi, apparently, due to oxidation of the contact mass surface inhibiting the formation of eta -Cu3Si.
