Copper and Nickel Phosphates

The catalytic properties of VSB-1 turn out to be very interesting. In terms of acid 

In spite of their highly open structures, both materials may be synthesized without structure directing agents. Since most transition metal phosphates containing template molecules typically cannot be calcined without pore collapse, template-free synthesis appears to be the most promising direction for the formation of new porous materials. The exciting properties observed in the VSB family are likely glimpses of what may occur in other transition metal phosphate systems once thermal stability problems are overcome.
