For better operation, hybrid monolithic aerogels were constructed by incorporating CTFs into polyvinylidene fluoride then casting in melamine resin foams. The obtained aerogels expressed high-efficient removal of anionic dyes coupled with convenient operation. This well-established metal-free porous material is a promising adsorbent candidate for anionic dyes selectively and even synergetic adsorption of cationic dyes in water remediation.In this investigation, a sequences of iron diselenide (FeSe2) nanomaterials as the competent and highly stable catalysts for the detoxification of aqueous organic dye pollutants such as Congo red (CR) and methylene blue (MB) through Electro-Fenton (EF) process using hydrogen peroxide as an initiator have been studied. The utilized selenium precursors include selenium metal, selenious acid (H2SeO3) and selenium dioxide (SeO2) which were employed for the synthesis of FeSe2 catalysts through a wet chemical strategy. It has been observed that based on the employed precursors, different morphologies ranges of the FeSe2 catalysts were obtained microgranualr particles to nano-stick to nanoflakes. The crystalline nature and phase purity of the obtained FeSe2 catalysts were determined through XRD, Raman and HR-TEM analyses which confirmed their orthorhombic ferroselite structure. Among the prepared FeSe2 catalysts, FS-2 (using H2SeO3) displayed better porous properties as compared to other catalysts and achieved the highest surface area of 74.68 m2g-1. The narrow bandgap (0.88 eV) and fast conversion of Fe2+/Fe3+ cycle of FeSe2 led CR and MB degradation of 93.3% and 90.4%, respectively. The outcome of this study demonstrates improved catalytic properties of FeSe2 nanostructures for the efficient detoxification of hazardous and toxic effluents.During reading,
