The stability and porous nature of a nanocomplex are of importance for the practical utility like in adsorption or
catalytic activities. Mesoporous Iron gallate (Fe-Ga) nanocomplex was fabricated by means of effective, simple,
convenient and rapid solvothermal method using triethylamine as a deprotonating agent for the organic linkers.
These nanocomplexes were then utilized as a catalyst for rapid degradation of cationic (Toluidine Blue (TB)) and
anionic (Rose Bengal (RB)) dyes in water without employing any auxiliary oxidants like Hydrogen Peroxide
(H2O2), Sodium Borohydride (NaBH4) etc. Analysis of the nanocomplex using various techniques like Powder
XRD, N2 (Nitrogen) adsorption/desorption, UV–vis spectroscopy and electron microscopy revealed mesoporous
(pore size =2.72 nm) structure with high surface area of 90.48 m2 g−1, uniform sizes of around 15–20 nm and
outstanding adsorption and degradation properties. The nanocomplex adsorbed, decolorized and decomposed
both the dyes within 10 min. Due to the negative zeta potential (14.6 ± 3.5) the particles preferably adsorb and
degrade cationic dye (TB) because of the presence of positively charged amine groups. Furthermore, the catalyst
is stable and reusable.
