Abstract

Компонент сигареты содержит катализатор на основе серебра для превращения монооксида углерода в диоксид углерода. Катализатор на основе серебра содержит частицы (например, наноразмерные или более крупные частицы) металлического серебра и/или оксида серебра, находящиеся в и/или на носителе в виде частиц оксида металла. Этот катализатор на основе серебра может быть введен в компонент сигареты, такой как начиночный скрошенный табак, сигаретная бумага и материал сигаретного фильтра, для уменьшения концентрации монооксида углерода в главной струе дыма сигареты во время курения. Катализатор также может быть использован и в сферах применения, не связанных с сигаретами.
