The present application provides aerosol processes for selectively incorporating properties of solid precursor particles into processed materials is provided. In one aspect, a carrier gas and a precursor mixture are injected into an aerosol generator. The precursor mixture includes solid precursor particles and a liquid component. One or more ultrasonic transducers are applied to the to the precursor mixture in the aerosol generator to aerosolize a portion of the precursor mixture that comprises solid particles that are smaller than a predetermined size. The aerosolized portion of the precursor mixture is transferred, via the carrier gas, into a reactor. The aerosolized portion in the reactor is then dried and sometimes reacted to produce solid product particles, and the solid product particles are collected in a particle collector.

Articles comprising a catalyst film comprising VOx, MoO.sub.3 or WO.sub.3, and TiO.sub.2 deposited on a substrate are disclosed. The articles are useful for selective catalytic reduction (SCR) of NOx in exhaust gases. Methods for producing such articles deposit a catalyst film on the substrate to form a coated substrate, which is then calcined. When used in an SCR process, the coated articles have enhanced activity for NOx conversion, reduced activity for SOx conversion, or both. Light-weight, coated articles having high catalyst loads can be fabricated at the same or reduced dimensions when compared with laminated articles, and increased kNOx/kSOx ratios are available even from coated articles having relatively thin catalyst films. The articles should have particular value for power plant operations, where coal and high-sulfur fuels are commonly used and controlling sulfur trioxide generation is critical.
