Abstract

Imagine turning algae from a lake into tiny, powerful particles that can clean water or fight bacteria. This review dives into the green synthesis of titanium dioxide (TiO2) nanoparticles using algal extracts, exploring how these natural ingredients interact with titanium precursors to create eco-friendly nanomaterials. While green synthesis is gaining buzz, detailed comparisons with traditional methods are scarce. We analyze the strengths and challenges of this approach, using algae like Bostrychia tenella and Sargassum filipendula to produce 5–15 nm spherical nanoparticles with stellar photocatalytic properties, perfect for environmental cleanup. These particles, characterized by UV spectroscopy, XRD, SEM, TEM, and FTIR, also show promise as antifouling agents in marine paints. By comparing this method to conventional ones, we highlight its potential and suggest ways to make it more practical for large-scale use, offering a sustainable path for nanotechnology.
