    • A supported heteropolyacid catalyst immobilized on mesoporous carbon is provided to allow firm chemical bonding between a heteropolyacid catalyst and mesoporous carbon, to activate properties as an oxidation catalyst, and to increase the selectivity during a catalytic reaction, particularly for preparing a methacrylic acid. A supported heteropolyacid catalyst immobilized on mesoporous carbon is obtained by immobilizing at least one anionic heteropolyacid selected from the group consisting of (a) Keggin type heteropolyacids including 12-molybdophosphoric acid(H3PMo12O40), 12-tungstophosphoric acid(H3PW12O40), 12-tungstosilicic acid(H4SiW12O40), 12-molybdotungstophosphoric acid(H3PMo12-xWxO40, x=0-12), 12-molybdovanadophosphoric acid(H3+xPMo12-xVxO40, x=0-12) and 12-tungstovanadophosphoric acid(H3+xPW12-xVxO40, x=0-12), and (b) Wells-Dawsons type heteropolyacids including 18-molybdophosphoric acid(H6P2Mo18O62), 18-tungstophosphoric acid(H6P2W18O62), 18-molybdotungstophosphoric acid(H6P2Mo18-xWxO62, x=0-18), 18-molybdovanadophosphoric acid(H6+xP2Mo18-xVxO62, x=0-18), 18-tungstovanadophosphoric acid(H6+xP2W18-xVxO62, x=0-18) and 18-tungstoneobiumphosphoric acid(H6+xP2W18-xNbxO62, x=0-18) to mesoporous carbon having cationic functional groups attached to the surface thereof through a chemical bonding.
    • 提供了固定在中孔碳上的负载型杂多酸催化剂,以使杂多酸催化剂和介孔碳之间的牢固化学键合活化作为氧化催化剂的性能,并提高催化反应中的选择性,特别是用于制备甲基丙烯酸。 固定在介孔碳上的负载型杂多酸催化剂是通过将至少一种选自(a)包括12-钼磷酸(H3PMo12O40),12-钨磷酸(H3PW12O40),12-钨磷酸(H3PW12O40)),12-钨硅酸的Keggin型杂多酸 (H 4 SiW 12 O 40),12-钼钨磷酸(H3PMo12-xWxO40,x = 0-12),12-钼钒酸(H3 + xPMo12-xVxO40,x = 0-12)和12-钨钨磷酸(H3 + xPW12-xVxO40,x = 0-12),(b)包含18-钼磷酸(H6P2Mo18O62),18-钨磷酸(H6P2W18O62),18-钼钨磷酸(H6P2Mo18-xWxO62,x = 0-18),18-钼磷酸 钼钨钒酸(H6 + xP2Mo18-xVxO62,x = 0-18),18-钨钒酸(H6 + xP2W18-xVxO62,x = 0-18)和18-钨磷钨酸(H6 + xP2W18-xNbxO62,x = 0-18 )与具有通过化学键合附着于其表面的阳离子官能团的介孔碳。
