XRD、Raman、FTIR和XPS（图2）分析进一步表明异质结中Co3O4和Co(OH)2两相共存，且具有三明治结构（即外层为Co(OH)2，中间层为Co3O4）。Co3O4/Co(OH)2异质结对应的拉曼光谱在589 cm-1处出现了一个新的特征峰，可能是由于Co3O4和Co(OH)2之间的相互作用引起的。

2020年3月15日 · Here, UiO-66- (COOH) 2 /ZnIn 2 S 4 Z-scheme photocatalyst decorated with MoS 2 nanosheets was designed and constructed as a novel 3D hierarchical structure via hydrothermal methods.

2019年11月23日 · Characterization of UiO-66-(COOH) 2. Before the analysis of mass spectrometry, we characterized the UiO-66-(COOH) 2 by different techniques, including XRD, FT-IR, SEM, UV-Vis, and BET. The results were demonstrated in Fig. 1. The SEM image of Fig. 1a shows the morphology of UiO-66-(COOH) 2 is spherical, and the particle size is about 200 nm ...
