Gd2NiMnO6 (GNMO NSs) nanostructures were synthesized via a Pechini method using propylene glycol (PG) as alkaline agent and various acid solutions as stabilizing agents. Effect of temperature, time and stabilizing agent was investigated in order to reach the finest nanostructures. The morphology, structure and magnetic property of nanostructures examined by XRD, SEM, HRTEM, FTIR, BET and VSM techniques. The photocatalytic degradation ability of GNMO NSs for the removal of different dyes from wastewater was reported. The obtained adsorbent with porous structure not only displayed fast rate adsorption, greater capacity adsorption, and promising selectivity adsorption to various dyes but also presented convenient magnetic separation characteristic. Rapid decomposition of dye observed with a rate of degradation, more than 90 % within the initial 105 min, which is qualified to the porous structure, great surface area (6.1735 m2 g−1), narrow of pore size (˜106.09 nm) assessed from adsorption-desorption isotherms analysis of N2 as well as outstanding electron accepting structures of the planned porous nanoparticles. Consequently, prepared nanocomposite indicated the great potential to be considered as an active and rapid magnetic adsorbent for the dye removal from wastewater.
