A Ni/Ce0.8Zr0.2O2 catalyst (NiCeZr-N) was synthesized by a facile co-nanocasting technique for syngas production from ethanol dry reforming. In addition, a series of characterization techniques, such as transmission electron microscopy (TEM), X-ray diffraction (XRD), inductive coupled plasma Emission Spectrometer (ICP), X-ray photoelectron spectroscopy (XPS), Raman and hydrogen temperature programmed reduction (H2-TPR) were selected to evaluate the physicochemical features of the as-prepared catalysts. Indeed, the results indicated that NiCeZr-N catalyst prepared by co-nanocasting method had a smaller particle size (<5 nm), relatively higher specific surface area (39 m2/g) and stronger metal-support interaction in comparison with another model catalyst obtained from conventional co-precipitation method (NiCeZr-P). Expectedly, these positive factors enabled NiCeZr-N catalyst to exhibit better activity and stability. Typically, ethanol is completely converted by using NiCeZr-N as catalyst and heating to 700 °C, and CO2 conversion was as high as 65.3%. Interestingly, H2/CO was close to 1.1 at 650 °C, which could be used as feedstocks of Fischer-Tropsch process. Particularly, no obvious fluctuation of ethanol conversion and the product selectivity was observed during 40 h time-on-stream stability test.

共纳米浇铸法合成高性能Ni/Ce0.8Zr0.2O2催化剂用于乙醇干重整

Ni/Ce0.8Zr0.2O2 催化剂 (NiCeZr-N) 通过简便的共纳米铸造技术合成，用于乙醇干重整生产合成气。此外，一系列表征技术，如透射电子显微镜（TEM）、X射线衍射（XRD）、电感耦合等离子体发射光谱仪（ICP）、X射线光电子能谱（XPS）、拉曼和氢气程序升温还原(H2-TPR) 被选择来评估所制备催化剂的物理化学特征。事实上，结果表明，与另一种模型催化剂相比，共纳米浇铸法制备的 NiCeZr-N 催化剂具有较小的粒径（<5 nm）、相对较高的比表面积（39 m2/g）和更强的金属-载体相互作用从传统的共沉淀法 (NiCeZr-P) 获得。预计，这些积极因素使 NiCeZr-N 催化剂表现出更好的活性和稳定性。通常，使用 NiCeZr-N 作为催化剂，加热到 700 °C 可以完全转化乙醇，CO2 转化率高达 65.3%。有趣的是，H2/CO 在 650 °C 时接近 1.1，可用作费-托工艺的原料。特别是，在 40 小时的运行时间稳定性测试中，没有观察到乙醇转化率和产品选择性的明显波动。
