Chemical Synthesis of Organo-siloxene 2D Materials from Calcium Di-Silicide: Characterization, Dielectric and Electrochemical Studies

Easily deposited ZnO nanorods on siloxene nanosheets: investigation of morphological, dielectric, ferroelectric, and energy storage properties

“…The results indicate that the value of the c / a ratio is almost constant in all the samples and is consistent with the value found in the flower-like spherical SiNSs@ZnO 27 and the literature. 36,37 In addition, the value of c / a ratio and Zn–O bond length in each composite slightly increase in the following order: SX-ZnO-5 < SX-ZnO-1 < SX-ZnO-3 < SX-ZnO-12.…”

“…In continuation with our previous work, 27 we extended our research by depositing nanorod-like ZnO on siloxene nanosheets using the same synthesis methodology, employing an equivolume mixture of water and ethanol as the solvent. The resulting composites SX-ZnO underwent comprehensive characterization using various spectroscopic techniques, including Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), and transmission electron microscopy (TEM).…”

“…The EDS spectra provide additional confirmation of the successful incorporation of the Zn element, accompanied by an observed increase in oxygen content in the synthesized samples, in contrast to the oxygen content found in neat siloxene. 27 The presence of iron (Fe) elements can be attributed to CaSi 2 impurities, while the chlorine (Cl) elements result from the exfoliation process involving HCl during the synthesis of siloxene.…”

“…The synthesis of siloxene nanosheets has been comprehensively detailed in our previous work. 27 Following a procedure analogous to the synthesis of SiNSs@ZnO outlined in the same report, the same method was employed to prepare SX-ZnO nanocomposites. In brief, in a Schlenk reactor, 200 mg of siloxene nanosheets, Zn(C 5 H 7 O 2 ) 2 ·H 2 O (1 eq.…”

Two-Dimensional Siloxene Nanosheets: Impact of Morphology and Purity on Electrochemistry

“…The intermetallic compounds known as Zintl phases have served as a versatile platform for the preparation of novel silicon-based materials . In particular, topochemical methods have been described for the preparation of two dimensional silicon, silicane, and siloxene , from calcium silicide, CaSi 2 . Notably, commercial CaSi 2 contains impurities, such as bulk crystalline Si and FeSi 2 .…”
