The properties and morphologies of o-CNTs supports and CoB/o-CNTs catalysts were characterized by FT-IR, XRD, SEM–EDX and TEM, which showed that o-CNTs possess different organic functional ...

2008年1月1日 · The XRD patterns of the Co x B (x = 1, 2, 3) series alloys are shown in Fig. 1. Main phases of alloys were orthorhombic CoB (PDF 65-2596), tetragonal Co 2 B (PDF 89-1994), and orthorhombic Co 3 B (PDF 89-3675), respectively. From the patterns, it can be seen that each alloy formed pure single phase and had good crystal structure.

本人做含铜的催化剂，由有机合成转至材料催化方向，基本上是从零做起，查看文献关于铜及其氧化物的XRD数据，觉得纷繁复杂，无力整理出比较完备的数据。

2024年1月1日 · Two-dimensional cobalt boride (CoB) nanosheets with comparatively high work function and low ΔGH* are prone to undergo low crystallinity under rigorous synthetic conditions. Herein, a facile method of thermal-induced molten salt melt is used to regulate the structure characters of CoB nanosheets.

2023年1月1日 · We report the structural behavior of CoB under extreme pressure and temperature conditions using a diamond anvil cell. The high-pressure XRD spectra at room temperature indicate that no phase transition occurs up …

X-ray diffraction (XRD) patterns of the as-deposited and heat-treated CoB films are compared in Fig. 1. As-deposited film exhibits a single broad peak at around 45° indicative of amorphous/...

2021年3月16日 · Chromite overburden (COB), considered as a waste material with 46% Fe and 0.8% Ni, is the only source of nickel in India. Iron and nickel from COB were recovered through reduction roasting, magnetic separation and smelting. In sintering, maximum Ni% was achieved at 1.0% S, 10% C inside and 10% C outside of the COB pellet.

Detailed view of figure 6–b CoB, CoB and Co2B phases in Figure 6–c [39,40]. In this study, tribological properties and characterization of borided Co–Mg alloys were investigated....

我用MCM-41负载的CoB催化剂在45℃、PH=7的条件下反应，但反应前后催化剂的XRD图相差很大（附件所示）。 反应后的XRD图中的峰跟二氧化硅和三氧化二铝基本都能对应上，想咨询下为什么会出现这么大的差异，是MCM-41结构被破坏了吗？

2025年1月23日 · The analysis revealed that bioplastics formulated with 6:6:1 and 4:6:1 exhibited superior tensile strength and physical properties. XRD results indicated an amorphous structure for the developed corn cob bioplastics, while SEM images showed changes in film morphology correlating with glycerol concentration.
