Green synthesis of protein-based nanomaterials and membranes for photocatalysis

Overview

This solution offers a green, one-pot synthesis approach that uses proteins as both reduction agents and surfactants to produce nanomaterials suited for photocatalysis. The method enables the creation of a broad library of materials, including Ag/AgCl and Pd, in flexible final forms such as sprays, suspensions, gels, and non-woven scaffolds. By programming the three-dimensional structure of protein scaffolds, the size, morphology, and form of the resulting nanoparticles, wires, and microcrystals can be engineered to meet specific application needs. The technology has been validated using common photocatalysis models such as methylene blue degradation, demonstrating feasibility for contaminant removal and related chemical processing applications.
