Paper Abstract

It has been demonstrated that continuous wave infrared CO2 laser radiation can be util-ized to rapidly produce active catalysts from inert precursors. The activity and selectiv-ity of Ca0 produced from Ca(OH)2 for the isomerization of 1-butene to cis- and trans-2-but-ene is discussed. Variation of the laser irradiation time produces catalytic activity and selectivity qualitatively similar to that resulting from conventional calcination at different temperatures. Pulsed infrared laser-induced reactions at catalytic surfaces are also discussed with emphasis on the dehydrobromination of 2-bromopropane and ethylene elimination from glycine ethyl ester hydrochloride at BaSO4 , A1PO4, and similar surfaces. Correlations are made of the extent of reaction with various experimental parameters including nature of the catalyst, laser frequency, laser fluence, number of laser pulses, and reagent-catalyst ratio.
