The XRD pattern of MnO(I) corresponds to a pure face-centred cubic MnO phase (mineralogical name manganosite, JCPDS Card 00-075-1090), which is isostructural with NaCl. No additional peaks due...

Chemical precipitation method was used for the synthesis of MnO nanoparticles. Phase formation of the prepared sample was analyzed with powder X-ray diffraction (PXRD) studies,...

Mn-based catalysts have attracted significant attention in the field of catalytic research, particularly in NOx catalytic reductions and CO catalytic oxidation, owing to their good catalytic...

2016年10月14日 · The formation of MnO nanoparticles was confirmed by X-ray diffraction (XRD). XRD pattern revealed the MnO nanoparticles which belonged to the cubic structure. In addition, the average grain size of the MnO nanoparticles could be determined by employing the Scherrer’s formula and it was found to be about 14 nm.

2024年2月24日 · Pure and Mg 2+, Ni 2+, Cd 2+ doped MnO 2 nanoparticles were synthesized by chemical co-precipitation method. These samples were characterised by PXRD, SEM, EDX, FTIR, UV–Vis-NIR, PL, Antibacterial, Cyclic Voltammetry, …

2024年4月5日 · Zirconium-fumaric based metal organic framework (MOF-801) was synthesised by ultra-sonication method. After synthesis, powder X-ray diffraction (PXRD), UV/Vis spectrophotometer and Fourier transform infrared (FT-IR), …

2018年1月9日 · Understanding and controlling the polymorphism of manganese dioxide (MnO 2) is of vital importance in many nanoscale applications. Here in situ powder X-ray diffraction (PXRD) in combination with in situ total X-ray scattering are used to reveal the formation mechanism as well as polymorph evolution of MnO 2 under

2024年7月23日 · The formation, phase purity, and crystalline nature of the as-synthesized samples (ZIF-8, MnO 2, and MnO 2 /ZIF-8 composite) have been studied by employing the PXRD method. The PXRD pattern of the MnO 2 demonstrated various diffraction peaks which suggested the presence of (110), (200), (310), (211), (301), (411), (600), (521), (002), and (521 ...

2019年3月1日 · The PXRD test has also been performed to further investigate the crystal structure of CDs 0.15-MnO 2, as observed in Fig. 2 d, the peaks at 2θ degree of 37.371° and 66.859° are ascribed to the δ-MnO 2, while the typical broad peak at 2θ degree of 20.9° is associated with the graphitic structure of CDs [35].

A series of manganese oxides (MnO, MnO2, Mn2O3 and Mn3O4) were synthesized and tested in heterogeneous activation of peroxymonosulfate (PMS) for phenol degradation in aqueous solutions.
