ABSTRACT
Based on a microscopic theory for collective resonances of metallic particle clusters, enhanced optical reactions from zeolite materials doped with metallic particles are studied. The influences of particle size, global density, and local tightness are essential for the appearance of collective resonances. Transmission electron microscopy (TEM) was carried out for three zeolite membranes, namely, CuMOR, CuFe2MOR, and CuFe3MOR. The TEM images show clearly that metallic particles are squeezed with nanometric distances. Models similar to the experimental TEM images are established as a larger system, where a group of metallic nanoparticles of various sizes is randomly distributed on a surface, which is simulated for the plasmon spectroscopy. Collective resonances were observed, which are related to the tightness, i.e. the average inter-particle distance. The collective resonances stem from the enhanced optical reactions due to the doping of metallic particles into zeolite materials. The study is useful for increasing the catalytic efficiency and yield from zeolite-containing materials.
