摘要：

The reaction between black carbon, in the form of n-hexane soot, and NO2/N2O4 has been studied at low nitrogen oxide pressures (9-35 ppm) and under the influence of simulated solar radiation. The rate law Rate = (k1 + k2 [soot]1/2)P(NO2) is consistent with a dual path mechanism and with earlier results at higher NO2/N2O4 pressures (50-240 torr). The effect of radiation is a reduction in rate due to photodissociation of NO2 with no apparent change in reaction mechanism.
