Implication

Demonstrates improved NOx reduction in diesel vehicles using zeolite catalysts, suggesting enhanced cold start performance.

Abstract

NH 3 selective catalytic reduction (NH 3 -SCR) is the most effective technology to alleviate NO x emission from diesel vehicles, but faces the cold start problem. Ideally, integrating passive NO x adsorption (PNA) and...
