Abstract: radicals, potentially hindering degradation. Smaller maghemite nanocatalysts (8 ± 2 nm) exhibited enhanced radical production due to increased surface area. Upon metal doping, manganese enhances ˙OOH radical production, while zinc inhibits ROS formation, and cobalt exerts nuanced influence. Additionally, catalytic efficiency in methylene blue degradation varied with the radical species, highlighting ˙OH radicals' superiority for rapid degradation (1 h) over ·OOH (24 h). Overall, this research provides valuable insights into nanoparticle synthesis, radical formation kinetics, and catalytic performance, contributing to the advancement of sustainable catalysis for environmental remediation.
