With the rapid development of.t.e world economy, complex air pollution has increasingly become a serious threat; for example, with haze events occurring frequently in various regions of.t.e globe. Recent evidence has indicated that secondary aerosols play an important role in haze formation, and that heterogeneous processes are among the main forces driving their explosive growth. In this regard, this paper reviews recent advances in the understanding of.t.e impact of heterogeneous processes on haze chemistry, including the impact on NO2chemistry, marine aerosols, and the hygroscopicity and optical properties of atmospheric aerosols. It is distinguished from past reviews on this topic by focusing mainly on new insights from the past five years. We summarize the main findings of.t.e impacts of heterogeneous processes on NO2chemistry, marine aerosols, and the physicochemical properties of atmospheric aerosols, and propose several f.t.re research directions.
