Nanoparticles for Water Treatment and Method for Preparing the Same

Silver-Bismuth Nanoparticle Technology for Aerobic Water Treatment

This technology relates to silver-bismuth-based nanoparticles for water treatment and a manufacturing technology therefor, providing high pollutant-removal efficiency under aerobic conditions.

Conventional nanomaterials for water treatment often require a light source or special environmental conditions, making practical operation difficult. This technology designs silver-bismuth nanoparticles that promote radical generation under aqueous basic conditions to improve the decomposition efficiency of organic pollutants.

As a result, it can secure pollutant removal performance without separate light irradiation and improve both operational convenience and purification efficiency in practical water-treatment processes.

Key Features:

• It applies silver-bismuth-based nanoparticles as an active material for water treatment.
• It decomposes organic contaminants by inducing hydroxyl radical generation in an aqueous basic environment.
• It improves applicability to real-world water-treatment processes by reducing dependence on an external light source.
