A CuCeZr composite oxide (Cu-Ce_0.8Zr_0.2O₂) was prepared via microwave-assisted co-precipitation method and employed in syngas production from dry reforming of renewable ethanol. Its physicochemical features were deeply investigated by a series of characterization technique (XRD, Raman, TPR, SEM and XPS etc). Indeed, the as-prepared composite oxide presented the flower-like morphology structure and exhibited the superior activity and stability even after 50 h on-stream tests for ethanol dry reforming. This attractive behavior was probably assigned to the uniform dispersion of active Cu species and the strong metal-support interaction which could not only efficiently stabilize Cu nanoparticles during the serious reaction conditions but suppress the deactivated coke formation over catalyst surface. The promising findings in this work might stimulate the development of value-added syngas production from renewable biomass-derived feedstocks.

CuCeZr复合氧化物（Cu-Ce _0.8 Zr _0.2 O ₂）是通过微波辅助共沉淀法制备的，并用于可再生乙醇的干重整制合成气中。通过一系列表征技术（XRD，拉曼，TPR，SEM和XPS等）对它的理化特性进行了深入研究。确实，所制备的复合氧化物即使在乙醇干重整运行50小时的在线测试后仍呈现出花状的形态结构，并显示出优异的活性和稳定性。这种吸引人的行为可能归因于活性铜物质的均匀分散和强金属-载体相互作用，这不仅可以在严重的反应条件下有效稳定铜纳米颗粒，而且可以抑制催化剂表面失焦的焦炭形成。
