One‐Pot Bio‐Assisted Synthesis of Stable Ag–AgCl System Using Jellyfish‐Based Scaffold for Plasmonic Photocatalysis Applications

Abstract Plasmonic assisted photocatalysis has emerged in the past decade as an efficient, high‐performance methodology. Such a system is often composed of the dispersal of noble metal nanoparticles on a semiconductor. In this architecture, the application of light at the plasmon frequency allows the separation of charge at the Schottky interface between the metal and the semiconductor, which can be further used for efficient catalysis. Here, a one‐pot green bio‐synthesis of Ag antibacterial nanoparticles attached to AgCl crystals while embedded in a jellyfish‐based eco‐friendly scaffold, is reported. The synthesis utilizes the chemical reduction properties of mucin protein found in the Jellyfish biomass, and thus the resulting Ag@AgCl system is firmly bound to the scaffold, making this membrane very stable. The system's photocatalytic activity is investigated by decomposing methyl orange and full electromagnetic simulations.
