Título: High yield synthesis of hydroxyapatite (HAP) and Palladium Doped HAP via a wet chemical synthetic route

Resumen: A novel procedure for the synthesis of both hydroxyapatite (HAP) and palladium doped HAP via a wet chemical precipitation method is described herein. X-ray Diffraction (XRD), Raman Spectroscopy, Scanning Electron Microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS) and Fourier Transform Infrared (FT-IR) Spectroscopy are utilised to characterise the synthesized material’s morphology, structure and crystallinity. The developed synthetic protocol produces high purity HAP with an average yield of 83.7 (± 0.10)% and an average particle size of 58.2 (± 0.98) nm, such synthesis has been achieved at room temperature and within a time period of less than 24 h. Additionally, in order to enhance the overall conductivity of the material, a range of Pd (2, 4 and 6 wt %) metal doped HAP has been synthesised, characterised and, for the first time, applied towards the competitive electrocatalytic detection of hydrazine, exhibiting a linear range of 50–400 μ M with a limit of detection (3 σ) of 30 μ M.
