Getting all steamed up : The active phase formed in situ in the catalytic hydrolysis of chlorinated compounds, such as CCl 4 , at relatively low temperatures consists of a lanthanide oxide chloride, as evident from vibrational frequencies at 125, 188, 215, 335, and 440 cm −1 in the Raman spectrum (see picture). This active phase remains stable as long as steam is provided, and produces CO 2 and HCl as the only reaction products.
