“…Since the discovery of crystalline aluminophosphates (1}3) with ordered micropores, a large number of new metal phosphates with an open framework have been synthesized and reported, and the metal elements distribute from main group elements to transition metal elements (4), especially molybdenum (5), zirconium (6), and hafnium (7). One of the most important reasons for this is the potential application in catalysis, adsorption, ionic conduction, ion exchange, electronics, and opto-electronics.…”

Structural features of AgCaCdMg2(PO4)3 and AgCd2Mg2(PO4)3, two new compounds with the alluaudite-type structure, and their catalytic activity in butan-2-ol conversion

“…The alluaudite-type structure shares similarities with garnet, langbeinite, nasicon and Sc 2 (WO 4 ) 3 structures and might display analogous catalytic behaviour [10]. The present work is devoted to the investigation of the catalytic activity of some compounds belonging to this structure-type, such as AgCaCdMg 2 (PO 4 ) 3 and AgCd 2 Mg 2 (PO 4 ) 3 .…”
