    摘要： The invention relates to a monolithic support member comprising channels with walls separating the channels from each other and having a coating deposited thereon, the non-coated channels having a polygonal cross-section profile, wherein the mean thickness dC of the coating in a corner of said cross-section profile is smaller than or equal to the mean thickness dE of the coating on an edge of said cross-section profile plus 85 micrometer; and further relates to a method for the preparation of such coated monolithic support member, the method comprising (i) providing a suspension having a viscosity in the range of from 0.5 to 100 mPas and having a solid content in the range of from 1 to 40 wt.-%, (ii) dispersing the suspension into a gas stream to obtain a gas stream comprising droplets having a droplet size in the range of from d10 greater than or equal to 1 micrometer to d90 smaller than or equal to 100 micrometer; and (iii) directing said gas stream comprising said droplet towards the monolithic support member along the axial direction of the channels of the support; and still further relates to the use of such coated monolithic support member, in particular as catalytic article in the automotive exhaust gas treatment.
