W-exchanged H−ZSM5 was prepared by sublimation of WCl6 at 673 K followed by hydrolysis of exchanged WCl x species at 523 K. D2 exchange with residual OH groups showed that each W initially replaced about two zeolitic protons for W/Al ratios of 0.29 and 0.44, consistent with the formation of (WO2)2+...
