衍射峰，归属于Co 3O 4的(111)、(220)、(311)、(400)、(511)和(440)晶面（JCPDS ，PDF#42-1467），表明Co 3O 4/ZnO(x )-ZIF 样品中Co 以Co 3O 4形式存在[29]。在2θ为34.40°、47.59°、56.53°、62.70°和67.76°处出现的衍射峰，归属于ZnO 的(002)、(102)、(110)、(103)和(112...
X- ray powder diffraction (XRD) patterns (Fig. 1a) demonstrate that the samples have identical peaks, which can be perfectly indexed to a pure Co3O4 (JCPDS card no. 42-1467)14. The broader peak implies the small size of the obtained products. Figure 1b shows a general morphology of ...
水热-热解法制备具有一维结构的Co3O4多晶
As shown in Figure 2 (black line), the diffraction patterns of the bare Co3O4 NAs in the 2h range of 10–80u could be indexed to the cubic phase Co3O4 (JCPDS Card No. 42-1467). The three peaks marked by "#" belong to the Ti substrate. In contrast, besides the peaks from Co...
结果表明，水热法制备的Co 3O 4催化剂均为尖晶石结构，不同沉淀剂影响催化剂形貌、氧化还原性能和催化分解N 2O 活性；含有钠离子沉淀剂制备而得的催化剂活性高于其他催化剂，其促进了Co 3+到Co 2+的还原过程，影响了钴离子化学环境，提高了给电子能力，弱化了催化剂中的Co —O 键，加快了反应过程中氧空位的...

3a. Besides the reflections from the Ti substrate, Co3O4 (Space group: Fd-3m, PDF#00-042-1467) was the only detectable crystalline phase before, during, and after electrochemical reac- tion conditions. Thus, the catalyst film essentially retained its Co3O4 structure under the entire ...
