| Abstract: | In a recent paper 1] we proposed that a Cu2+ species interacting with the support was responsible for maintaining the catalytic activity of CuCl2 catalysts used in the methane oxyhydrochlorination reaction (CH4+HCl+O2 chloromethanes). This species was detected on Al2O3 and TiO2 supports but it did not appear on SiO2. In this paper we report EPR results which provide a direct characterization of this species and correlate well with the observed trends in activity.
