Abstract

Abstract: The nanocatalysts of compound metal oxides ((La2 CuO4 )0.5 (CNZ-1)0.5, denoted as LCO5-CNZ) composed of perovskite-like oxides La2 CuO4 and CuO/ZnO/Al2 O3 were prepared by co-precipitation and ball milling methods. The steam reforming of methanol (SRM) to H2 and CO2 over the nanocatalysts was experimentally studied at a molar ratio of 1.6 (H2 O/methanol). The methanol solution catalyzed by LCO5-CNZ can be completely converted into H2, CO2 and a small amount of CO at the reaction temperature of 270 °C with a liquid hourly space velocity of 1.2 ml/(g·h). Simultaneously, under the same conditions, the catalysts of La2 CuO4 and CuO/ZnO/Al2 O3 were tested. Compared with the catalyst of pure La2 CuO4, LCO5-CNZ showed higher methanol conversion rate and H2 yield. Compared with the conventional Cu-based catalyst of CuO/ZnO/Al2 O3, LCO5-CNZ has both better CO selectivity and better H2 selectivity. It could be concluded that LCO5-CNZ with special structure has a significant improvement in catalyzing performance of SRM benefiting from the synergetic effect among perovskite-like La2 CuO4 and Cu/Zn/Al oxides.
