Abstract: The main factors in the synthesis of layered zirconium phosphate phenylphosphonate Zr(PO4H)2-n(PO3Ph)nwere investigated. At F-/Zr4+=12 and H3PO4/Zr4+=20, a series of homogeneous Zr(PO4H)2-n(PO3Ph)n(n=0~2) were synthesized by changing the amount of phenylphosphonic acid. The crystals are thermally stable below 400 ℃. The phenyl groups in the layered structure can be sulfonated almost quantitatively. The sulfonated products Zr(PO4H)2-n(PO3PhSO3H)nhave abundant acidic sites and they are also stable below 300 ℃.
