. Generally, the bimetallic alumina supported catalysts (usually NiMo and less CoMo/Al 2 O 3 [ 28 ]) in sulfided form were studied for the HDO reaction of vegetable oils. There is still limited information available about the application of the non

. Recycling of the MCM-41 supported catalyst Easy recyclability and the prolonged retention of catalytic activity are very important for industrial applications. In order to test the reusability, we carried out the coupling of iodobenzene or 1-iodo-3

acid strength of the supported catalyst was increased with an increasing loading amount of TPA from 5 up to 10 wt% and is constant for higher loading amounts. These results confirm maximum dispersion of TPA on the MCM-41 for the 10 wt% catalyst which is

/Al = 2.43) were obtained from Nankai University catalyst Co., Ltd. The supported catalysts were prepared by impregnating the NaY zeolite with an appropriate amount of the aqueous solution of KNO 3 for 12 h. The obtained mixture was dried in an oven at

explained as follows. During the preparation of the supported catalyst, tungstic acid, H 2 O 2 and H 3 PO 4 were first mixed according to the ratio in the literature [ 4 ] in order to get the active species of [(PO 4 ){WO(O 2 ) 2 } 4 ] 3− . Second, the

the alumina-supported catalysts. But BET and XRF characterizations revealed that vanadium element does exist in the catalysts. It is a clear indication that V 2 O 5 phase is in a highly dispersed state [ 27 ]. XPS analysis

are much more active in the CO oxidation than the Au/inert oxides systems. These facts suggest that reducibility of the support may be another factor influencing catalytic behavior of the Au/oxide support catalysts. It can be supposed that oxides of
