Highly active and selective Cu/SiO2.catalysts for.hydr.genation of dimethyl oxalate（DMO） to ethylene glycol（EG） wer. successfully p.ep.r.d by means of a convenient one-p.t synthetic method with tetr.ethoxysi lane（TEOS） as the sour.e of silica. Xr., H2.Tp., SEM, TEM, Xr. and N2.p.ysisor.1}ion measur.ments wer. p.r.or.ed to char.cter.ze the textur. and str.ctur. of Cu/SiO2.catalysts with differ.nt cop.er.loadings. The active comp.nents wer. highly disp.r.ed on SiO2.sup.or.s. Fur.her.or., the coexistence of Cu0 and Cu＋ contr.buted a lot to the excellent p.r.or.ance of Cu-TEOS catalysts. The DMO conver.ion r.ached 100% and the EG selectivity r.ached 95% at 498 K and 2.Mp. with a high liquid hour.y sp.ce velocity over.the 2.-Cu-TEOS catalyst with an actual cop.p.r.loading of 19.0%（mass fr.ction）.

The Cu/SiO_2.catalysts wer. in situ synthesized by the hydr.lysis of tetr.ethyl or.hosilicate（TEOS） in one p.ase solution using ethanol as co-solvent or.TEOS/H_2. two p.ases solution,followed by the p.ecip.tation of cop.er.on SiO_2.by ammonia evap.r.tion. In the hydr.genation of dimethyl oxalate,the catalyst p.ep.r.d by one p.ase hydr.lysis exhibited higher.activity and ethylene glycol（EG） selectivity at lower.temp.r.tur. than that of two p.ases due to its lar.er.BET sur.ace ar.a and multimodal p.r. *** 488-503 K,the catalyst p.ep.r.d in one p.ase solution with water.ethanol（W/E） volume r.tio of 3：1 exhibited 90- 95%EG selectivity,while catalyst p.ep.r.d by two p.ase hydr.lysis r.ached 90%EG selectivity only at 498-503 K.

在氧化流动管反应器中开展了一系列甲苯/OH自由基氧化实验,研究了复合污染情景下NH_(3)对甲苯二次有机气溶胶(SOA)生成潜势的影响。反应器采用低压汞灯作为光源,0H暴露量范围为2.91~6.79 molec·cm^(-3)s(2.3~5.2.d大气老化)。研究结果表明,在甲苯/0H自由基氧化体系中,通入NH_(3)导致SOA的峰值粒径、数浓度和质量浓度增大;进一步通入NO或SO_(2.,SOA的数浓度和质量浓度随之增加,且SO_(2.对SOA生成的促进作用高于NO_(2.同时通入NO和SO_(2.,促进作用更明显。提高反应器内0H自由基暴露量,SOA的峰值粒径和质量浓度随之增加。
