英文摘要Dioxin-like chlorinated aromatics and NOx are toxic compounds that are typically co-released from thermal industrial processes. Nevertheless, there are few studies reporting their synergetic disposal technology. A designed two-step coprecipitation method was developed to synthesize a novel three-dimensional ball-like Ce-Ti-Al composite oxide (Ce0.2TiAl alpha Ox) micro/nanomaterial to simultaneously dispose 1,2,4-trichlorobenzene (1,2,4-TrCBz, as the model compound) and NO in a fixed-bed flow reactor at 300 degrees C. The prepared Ce0.2TiAl alpha Ox micro/nanomaterial exhibited superior activities to Ce0.2TiOx. This featured the relative increase of 1,2,4-TrCBz degradation and NO conversion efficiencies by 8.0-14.1% and 5.2-33.3%, respectively. NO had a positive effect on the degradation of 1,2,4-TrCBz and induced a significant increase in the activity of the Ce0.2TiAl alpha Ox catalysts. In the presence of NO, 1,2,4-TrCBz was slightly dechlorinated in a stepwise manner to monochlorobenzene and oxidized to small molecules such as formic acid. The oxidative degradation pathway of 1,2,4-TrCBz over Ce0.2TiAl alpha Ox was proposed to proceed via the Mars-van Krevelen mechanism that accounts for the high mobility of the reactive oxygen species, such as O2-, O-2(-), and O-, the unique redox properties of CeO2, the positive effect of NO, and the interactive effect among the different material components.
