In-situ green synthesis of Zn/Fe co-doped NiO nanocatalysts using Rheum ribes root extract for band-gap engineering and enhanced solar-light-driven photocatalytic degradation of methylene blue.
In-situ green co-doping synthesis offers a sustainable and efficient route for tailoring the structural, optical, and catalytic properties of nanocatalysts, enabling enhanced charge separation, band-gap modulation, and superior photocatalytic performance under solar-light irradiation. This study presents a sustainable...
