An environmentally friendly and facile method for the synthesis of small‐sized Au–Ag alloy nanoparticles is proposed. The method involves the coreduction of HAuCl 4 and AgNO 3 using Lysimachia christinae polysaccharide as reductant and stabiliser at 85°C. The synthesised alloy nanoparticles with a mean diameter of 3.81 nm are stable in solution due to the stabilising effect of the polysaccharide. Furthermore, Au–Ag nanoparticles have first been introduced into cigarette filter to serve as a synergistic catalyst for reducing CO in mainstream smoke.
