催化剂利用XRD、Raman、SEM、TEM等常规技术进行了表征,我们也合成了不同Cu/Co比的催化剂材料,主要是Cu掺杂在Co3O4晶格中,形成立方块体结构,结晶性良好(Figure 1)。其他数据文章中有介绍,这里不再过多赘述。 Figure 1.Preparation strategy a...
以共沉淀法制得的Co3O4为载体,采用两步法负载Au和Cu制得了一系列Au— Cu/Co3O4双金属催化剂,考察了Au-Cu/Co3O4双金属催化剂完全催化氧化乙烯的性能,并通过X射线衍射(XRD),高分辨透射电镜 (HRTEM),Hz程序升温还原(H2-TPR)和O2程序升温脱附(O2-TPD)对催化剂进行了表征.活性测试结果表明:负载型Au- Cu/...

The nitrate (NO3−) electroreduction into ammonia (NH3) represents a promising approach for sustainable NH3 synthesis. However, the variation of adsorption configurations renders great difficulties in the simultaneous optimization of binding energy for
Based on XRD and EDS analysis, it was demonstrated that there is no considerable impurity in the synthesized samples. The optimal values for the factors of the Residence time, Cu amount, and Dose were demonstrated to be 46, 0.4, and 0.966, respectively, for obtaining the highest possible ...
Manganese oxide (Mn3O4) and metal (Cu, Co and Ni) substituted Mn3O4 catalysts have been synthesised using single step solution combustion method. Catalysts were characterized using XRD, XPS, SEM and TEM and BET. The particle sizes of the catalysts were between 21 and 27 nm. CO oxidation...
