摘要

Abstract

Vanadiumoxide (VO

) nanostructures

synthesized by hydrothermal treatment using dodecylamine as template

were evaluated for the selective catalytic reduction of NOx with ammonia (NH

-SCR). The effect of solvent type in the reaction mixture (EtOH/(EtOH+H

O)) and time of hydrolysis was studied. The obtained materials were characterized by XRD

SEM

TEM and BET. The VO

nanorods (80-120 nm diameter and 1-4 μm length) were synthesized in 25 vol% EtOH/(EtOH+H

O) and the open-ended multiwalled VO

nanotube (50-100 nm inner diameter

110-180 nm outer diameter and 0.5-2 μm length) synthesized in 50 vol% EtOH/(EtOH+H

O). VO

nanotubes performed the superior NH

-SCR activity under a gas hourly space velocity of 12

000 h

-1

at low temperature of 250℃ (NO

conversion of 89% N

selectivity of 100%)

while most of the developed Vanadia base catalysts are active at high temperature (350℃). The superior NH

-SCR activity of VO

nanotubes at low temperature is related to nanocrystalline structure

special

nanotube morphology as well as high specific surface area.
