Sm 2 Ti 2 O 7 /HZSM 5 composite material was prepared by s ol gel method. Pyrochlore structured Sm 2 Ti 2 O 7 formed in the unloaded Sm 2 Ti 2 O 7 and Sm 2 Ti 2 O 7 /HZSM 5. EDS mappings of Sm and Ti prove the loading of Sm 2 Ti 2 O 7 on the surface of HZSM 5. Typical absorptions of Sm 2 Ti 2 O 7 appear in the infrared spectra of the Sm 2 Ti 2 O 7 /HZSM 5 samples calcined at temperature over 800 o C . The maximum amount of hydroxyl radicals is produced on the Sm 2 Ti 2 O 7 /HZSM 5 sample calcined at 800 o C . E CB and E VB of Sm 2 Ti 2 O 7 /HZSM 5 at 800 o C are 0.66 V and 2.77 V, respectively. The supported Sm 2 Ti 2 O 7 /HZSM 5 has much improved activity as compared to the unloaded Sm 2 Ti 2 O 7.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
