Synthesis, Structural, FT-IR, UV-Vis. Spectroscopic, Thermal, and BET Studies of Magnesium Ion Doped Strontium Pyrophosphate Nano-Particles

Abstract

Pyrophosphates are very useful as bioactive ceramics; in particular, calcium pyrophosphate has made impressive progress as biocompatible material promoting tissue formation. 2% Mg, 5% Mg, and 10% Mg ion doped SrPPi nano-particles are synthesized using a surfactant-mediated approach. The powder X-ray diffraction pattern confirms the tetragonal structure of materials and nano-structured in nature. Transmission electron microscopy study confirmed the nano-size and the dimensions in the range from 7.46 to 51.70 nm. P-O-P and PO3 have both symmetric and asymmetric stretching vibrations, according to the Fourier transform infrared (FT-IR) spectroscopy investigation. The direct optical energy band gap for 2% Mg, 5% Mg, and 10% Mg ion doped Sr2P2O7 samples is found to be 4.98, 4.75, and 4.55 eV using UV-nuclear imaging resonance absorption spectroscopy spanning the spectral range of 210-1200 nm. EDAX analysis confirmed the elemental presence. Thermogravimetric analysis proved that the sample included water molecules. According to thermogravimetric analysis, the samples become anhydrous and almost remain stable when heated over 600–1000°C. Photoluminescence study is indicating the emission in the visible range. Brunnauer-Emmett-Teller (BET) analysis gives information on surface area and pore size.

Investigating the electrochemical and antibacterial activities of nickel pyrophosphate [a-Ni2P2O7] nanostructures

“…The calculated crystalline size is found to be 44 nm and 59 nm for the NP-2 and NP-3 nanomaterials respectively. By increasing the annealing temperature, the crystallite size increases, which is confirmed by the XRD pattern [10][11][12][13][14].…”
