摘要：
Exfoliated montmorillonite (ex-MMT) incorporated with H3PW12O40 (HPW) was prepared by introducing HPW to cetyltrimethylammonium bromide modified MMT. HPW-ex-MMT was characterized by XRD, FT-IR, TGA, N-2 adsorption-desorption, UV-vis DRS, P-31 MAS NMR, contact angle and SEM. CTAB played a decisive role in the introduction and dispersion of HPW on ex-MMT. HPW-ex-MMT exhibited good catalytic performance in one-pot synthesis of oxime from alcohol with aqueous ammonia and hydrogen peroxide. The high catalytic performance is attributed to highly dispersed HPW over ex-MMT and highly hydrophobic surface of 20% HPW-ex-MMT. The catalyst could be recovered and reused several times without significant deactivation of catalytic performance. (C) 2016 Published by Elsevier B.V.
