Nanohybrid organometallic particles of ‘C-γ-alumina’ and ‘C-α-alumina’ have been synthesized through thermal decomposition method. Simultaneous propulsion of organic herb turmeric and inorganic aluminum nitrate on temperature 700°C disclosed formative ability within turmeric molecules that wisely derived a covalent-ionic bonded prominent self-assembled structure of C-γ-alumina in an uncontrolled environment. Turmeric transformed alkaloid carbon derivatives provoked activation in nano C-γ-alumina. In-vitro elaboration of minimal inhibitory concentration (MIC) against pathogenic strain Acinetobactor Sp. and, ex-situ TDS measurement of contaminated water further showed enhance biochemical efficacy of C-γ-alumina nanoparticles in different surrounding environments. Phase transition of C-γ-alumina into more thermodynamically stable C-α-alumina retained on temperature 700°C during a second thermal decomposition propelled by fuel hexamine. Occurrence of a single C-O carbonyl bond in FTIR absorption spectra, obtained for both carbon aluminates latter verified organometallic nature of compounds. Phase transition characteristics, crystalline size and crystalline phases were determined by X-Ray diffraction. High resolution TEM and FESEM imaging’s displayed spherical surface morphology of C-γ-alumina and captured rough surface features in transformed C-α-alumina at down to the nanoscale.
