Two exam\u00adples will be used to illus\u00adtrate this research approach: de-NOx for auto\u00admo\u00adtive exhaust after-treat\u00adment and ammo\u00adnia decom\u00adpo\u00adsi\u00adtion cat\u00ada\u00adlysts for CO free hydro\u00adgen generation.While HT screen\u00ading is a macro\u00adscop\u00adic analy\u00adsis tech\u00adnique, we are also inter\u00adest\u00aded in observ\u00ading non-lin\u00adear phe\u00adnom\u00ade\u00adna on work\u00ading cat\u00ada\u00adlysts in situ on the microscale using spec\u00adtro\u00adscop\u00adic imag\u00ading based on ellip\u00adsom\u00ade\u00adtry. The col\u00adlec\u00adtive, glob\u00adal behav\u00adiour of a cat\u00adalyt\u00adic sys\u00adtem depends on the effec\u00adtive com\u00admu\u00adni\u00adca\u00adtion of local reac\u00adtiv\u00adi\u00adty vari\u00ada\u00adtions to dis\u00adtant points in the sys\u00adtem. One mode of com\u00admu\u00adni\u00adca\u00adtion occurs via par\u00adtial pres\u00adsure fluc\u00adtu\u00ada\u00adtions in the gas-phase above the cat\u00adalyt\u00adi\u00adcal\u00adly active sur\u00adface. This gas-phase cou\u00adpling mode is con\u00adsid\u00adered to be most effec\u00adtive under vac\u00adu\u00adum con\u00addi\u00adtions, where the mean free path between mol\u00ade\u00adc\u00adu\u00adlar col\u00adli\u00adsions is large. We take advan\u00adtage of a spa\u00adtial\u00adly dis\u00adtrib\u00aduted sys\u00adtem of iso\u00adlat\u00aded chem\u00adi\u00adcal oscil\u00adla\u00adtors to inves\u00adti\u00adgate the details of gas-phase com\u00admu\u00adni\u00adca\u00adtion in the 10\u20133 Torr range. Char\u00adac\u00adter\u00adi\u00adza\u00adtion of local gas-phase vari\u00ada\u00adtions, in con\u00adjunc\u00adtion with local kinet\u00adic activ\u00adi\u00adty on the sur\u00adface, shows that sur\u00adface\/\u00adgas-phase inter\u00adac\u00adtion might dif\u00adfer from the con\u00adven\u00adtion\u00adal assump\u00adtion of a gra\u00addi\u00adent free, mol\u00ade\u00adc\u00adu\u00adlar flow envi\u00adron\u00adment near the sur\u00adface. This analy\u00adsis pro\u00advides a quan\u00adti\u00adta\u00adtive esti\u00admate of the effec\u00adtive gas-phase cou\u00adpling length in a het\u00adero\u00adge\u00adneous sys\u00adtem. This cou\u00adpling length was found to be in agree\u00adment with sur\u00adface imag\u00ading results which qual\u00adi\u00adta\u00adtive\u00adly showed cou\u00adpling between oscil\u00adla\u00adtors. 2009 Spring Sym\u00adpo\u00adsium Jochen Lauter\u00adbach Depart\u00adment of Chem\u00adi\u00adcal Engi\u00adneer\u00ading Uni\u00adver\u00adsi\u00adty of Delaware Newark, DE Abstract \u2014 We have been using high-through\u00adput (HT) approach\u00ades based on rapid-scan FTIR hyper\u00adspec\u00adtral imag\u00ading in the mid-infrared to screen cat\u00ada\u00adlyst for\u00admu\u00adla\u00adtions for the dis\u00adcov\u00adery and opti\u00admiza\u00adtion of new and improved mate\u00adri\u00adals.

\nAbstract<\/strong> \u2014 We have been using high-through\u00adput (HT) approach\u00ades based on rapid-scan FTIR hyper\u00adspec\u00adtral imag\u00ading in the mid-infrared to screen cat\u00ada\u00adlyst for\u00admu\u00adla\u00adtions for the dis\u00adcov\u00adery and opti\u00admiza\u00adtion of new and improved mate\u00adri\u00adals. In com\u00adbi\u00adna\u00adtion with HT meth\u00adods, we also employ a vari\u00adety of more tra\u00addi\u00adtion\u00adal spec\u00adtro\u00adscop\u00adic meth\u00adods to under\u00adstand the under\u00adly\u00ading fun\u00adda\u00admen\u00adtal sci\u00adence.<\/p>\n
