Abstract

When particles of catalytic materials become less than 50 nm they start toexhibit a stronger catalytic activity compared to their bulk counterparts. Nano-particles are thus good candidates for manufacture of highly activecatalysts. Nanometer sized particles of catalytic materials may be generated athigh temperatures in flames. The direct deposition from gas phase on a ceramicsubstrate tube of flame-generated particles leads to a uniform, porous layer ofsmall particles, masking the coarser structure of the substrate tube. The methodlooks promising for manufacture of catalytic filters and membranes.
