Ozone production efficiency

WebJan 8, 2009 · Ozone production efficiency of NO x (OPE x ), which is defined as the number of ozone molecules produced by one NO x molecule in the NO x -catalyzed photochemical reactions before it is removed from the system, is among the critical parameters of ozone chemistry [ Liu et al., 1987 ]. WebOzone formation is driven by two major classes of directly emitted precursors: nitrogen oxides (NOx) and volatile organic compounds (VOC). The relation between O3, NOxand …
