Abstract

Water pollution stemming from textile dyes, particularly methylene blue (MB), represents a formidable challenge to both the environment and human well-being. In response to this pressing issue, scientists have redirected their focus toward eco-friendly nanocatalysts as a viable remediation strategy. Nanocatalysts crafted from precious metals like platinum, palladium, and gold have indisputably demonstrated their efficacy in combatting water pollution. Nonetheless, their restricted availability and substantial costs have spurred investigations into non-precious metal-based nanocatalysts. Research outcomes have revealed that non-noble metal (FeNi)-based nanocatalysts, synthesized using natural reductants, exhibit highly promising performance in degrading methylene blue. These alternatives not only deliver impressive efficiency but also incur lower production expenses compared to their noble metal counterparts. The ecological benefits inherent in these nanocatalysts offer a sustainable means of mitigating water pollution attributed to textile dyes. Through detailed synthesis experiments, precipitation-assisted method demonstrated a slightly superior yield of 69.11% with catalytic activity of 16260 μmol MB/g_NiFe.
