Abstract: We set up a photovoltage spectrometer suitable for studing catalysts and carried out an investigation of a series of bis- (silico-11-tungstic) -rare earth heter-opoly acids called for RE (SiW)2. Aset of typical SPV spectra of RE(SiW2) are given. The threshold wavelength (TW) producing surface photovoltage varies with the displacement of REelement, and is a vaiuable information for studing catalyst.
