Résumé:
The environmental protection and remediation of environmental problems became major issues of the 21st
century. However, nanotechnology is now regarded as a distinct field of research in modern science and
technology. Among the various approaches currently available for the generation of metallic nanoparticles, plant
materials are the most readily available. In this review, we have provided information on the method and agents
used for the green synthesis of hematite Fe2O3 nanoparticles, the hematite was synthesized using extract of
Roman Nettle (RN) and iron nitrate. Structural, morphological and optical proprieties were characterized by
TEM, DRX, SEM, BET, RD and FTR. The results show a formation of nanoparticles with a diameter around
61nm with a specific surface area of 96.2 m²/g
