Microwave-assisted synthesis of a thermally stable Zn-containing aluminophosphate with ERI-zeotype structure templated by diquaternary alkylammonium

Abstract

Microwave-assisted hydrothermal synthesis of a Zn-containing aluminophosphate with ERI-zeotype structure, was successfully prepared by using N,N,N,N 0 ,N 0 ,N 0 -hexamethyl-1,6hexanediammonium (Me 6 -diquat-6) as the template. The assynthesized zeolite possesses high thermal stability, large surface area and weak and medium acid sites, which will be potentially interesting for applications in adsorption and catalysis.

High Catalytic Performance and Sustainability of Zr Modified Aluminophosphate for Vapor-Phase Selective O-Methylation of Catechol with Methanol

“…Amorphous aluminophosphates, which possess both acid and base sites, are considered effective catalysts for vapor-phase O-methylation of catechol with methanol [12][13][14][15][16]. The physicochemical properties of aluminophosphate have been reported to depend on modifying catalyst with various metals, optimizing catalyst compositions, and improving catalyst preparation routes [16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Generally, aluminophosphates with specific structure are usually synthesized with various surfactant templates.…”

“…Hence, it is still important to develop a simple approach to fabricate aluminophosphates with high activity and selectivity for vapor-phase O-methylation of catechol with methanol. It is commonly acknowledged that various metals, especially transition metal, introduced to aluminophosphates could alter the acid-base property of aluminophosphates [17][18][19][20][21][22][23][24][25][26].…”
