The growing quantity of artificial dye pollution in industrial wastewater poses important environmental and well being considerations, creating an pressing want for environment friendly and sustainable remediation methods. Herein, we report the fabrication of bimetallic Cu-Ni oxide doped porous carbon nanofibers (Cu:Ni:PCF) by way of block copolymer templating, electrospinning, and managed pyrolysis. The hierarchical buildings mixed with uniformly dispersed copper and nickel oxide nanoparticles inside the carbon matrix, offered plentiful energetic websites, enhanced floor cost modulation, and multifunctional adsorption capabilities. The Cu:Ni:PCF adsorbent demonstrated glorious uptake of anionic MO and cationic MB, reaching most adsorption capacities of 950 and 985 mg g⁻¹, respectively. Speedy adsorption kinetics have been noticed, reaching equilibrium inside 15 min. The kinetics knowledge have been greatest described by a pseudo-second-order mannequin, indicating a robust adsorption interplay. The equilibrium knowledge match the Langmuir isotherm mannequin, suggesting monolayer protection on uniform adsorption websites.Notably, the adsorbent maintained its structural integrity and demonstrated excessive recyclability, retaining greater than 90% of its preliminary adsorption capability after 5 consecutive adsorptiondesorption cycles. These findings underscore the potential of Cu:Ni:PCF as a sturdy and environment friendly materials for eradicating numerous dye contaminants from wastewater, representing a promising technique for sensible environmental remediation.
