ABSTRACT:
Smoking articles and filters, which involve the use of carbon-coated molecular sieve sorbents are provided. The carbon-coated molecular sieve sorbent has a carbon coating within pores of a mesoporous molecular sieve. The carbon-coated molecular sieve sorbent provides selective adsorption of one or more constituents from mainstream smoke, such as acrolein or 1,3-butadiene. Thus, certain constituents from cigarette smoke will be selectively removed, while maintaining other constituents, such as those that contribute to flavor. Methods for making cigarette filters and smoking articles using the carbon-coated molecular sieve sorbent, as well as methods for smoking a cigarette comprising the carbon-coated molecular sieve sorbent, are also provided.
