Abstract

Single phase mixed zirconium phosphate phenylphosphonates, ZrP(PP)x, were prepared by two different synthetic approaches: reaction of gels of nanosized α-zirconium phosphate in propanol with solutions of phenylphosphonic acid (H2PP), leading to the topotactic exchange of monohydrogen phosphate group...
