摘要：
The invention provides a coating composition suitable for use in forming a coating that can reduce the concentration of pollutant gases in the environment, the coating composition comprising polymeric material together with mesoporous titania particles. The particles have a continuous exterior convex surface and a particle diameter of greater than or equal to 1µm but less than or equal to 50µm, and a BET specific surface area of from 30m2/g to 350m2/g, and a modal pore diameter of greater than or equal to 5nm but less than or equal to 50nm, and a pore size distribution such that 85% or more of the total pore volume is associated with pores with a diameter of 10 microns or less. The coating composition comprises from 0.01% to 10% by volume of said particles, relative to the total volume of the coating composition and comprises from 5% to 99.99% by volume of polymeric material, relative to the total volume of the coating composition.A coating formed from said composition can be used for the removal of pollutant gases, especially in conditions where the coating is exposed to UV radiation from sunlight.
