\nAbstract<\/strong> \u2014 Mobil com\u00adpo\u00adsi\u00adtion of mate\u00adr\u00adi\u00adal No. 41 (MCM-41) was dis\u00adclosed in 1992 and short\u00adly after a research project was ini\u00adti\u00adat\u00aded at Yale to use these mate\u00adri\u00adals to demon\u00adstrate a radius of cur\u00adva\u00adture effect on cat\u00adalyt\u00adic activ\u00adi\u00adty. The \u201cradius of cur\u00adva\u00adture\u201d effect implies a change in the sol\u00adid sur\u00adface ten\u00adsion of the pore wall as the pore diam\u00ade\u00adter (cur\u00adva\u00adture) is changed that is expect\u00aded to change the activity\/selectivity of an iso\u00adlat\u00aded cat\u00adalyt\u00adic site on the pore wall of the sup\u00adport. An iso\u00adlat\u00aded site can be formed by iso\u00admor\u00adphous sub\u00adsti\u00adtu\u00adtion (dur\u00ading syn\u00adthe\u00adsis) of some Si cations by V cations in the MCM-41 sil\u00adi\u00adca matrix. Sev\u00ader\u00adal labs have report\u00aded that iso\u00adlat\u00aded V sites on a sil\u00adi\u00adca sup\u00adport are prefer\u00adable to dimers, oligomers or poly\u00admers of van\u00addia on a sil\u00adi\u00adca sup\u00adport for the oxi\u00adda\u00adtion of methanol to formalde\u00adhyde. MCM-41 might have an advan\u00adtage rel\u00ada\u00adtive to oth\u00ader sil\u00adi\u00adcas because of its very high sur\u00adface area, >1000 m2<\/sup>\/g. Both the air oxi\u00adda\u00adtion of methanol and methane to formalde\u00adhyde have been used as probe reac\u00adtions for cat\u00adalyt\u00adic char\u00adac\u00adter\u00adi\u00adza\u00adtion of V-MCM-41. SBA-15 has a sim\u00adi\u00adlar struc\u00adture to MCM-41, but larg\u00ader pores and thick\u00ader walls. Iso\u00admor\u00adphous sub\u00adsti\u00adtu\u00adtion of V dur\u00ading syn\u00adthe\u00adsis is not prac\u00adti\u00adcal, but well dis\u00adpersed V can be pre\u00adpared post-syn\u00adthe\u00adsis by graft\u00ading (reac\u00adtion with sur\u00adface hydrox\u00adyls). The activ\u00adi\u00adty for methanol oxi\u00adda\u00adtion on V-MCM-41 and V-SBA-15 will be com\u00adpared and dis\u00adcussed.
