X-ray-induced synthesis of gold nanoparticles and in situ XAFS measurements

Abstract

X-ray irradiation offers a promising avenue to expedite the green synthesis of nanoparticles with high efficiency, simplicity, and environmental friendliness. X-ray technologies, such as X-ray photoelectron spectroscopy (XPS), X-ray absorption fine structure (XAFS), and synchrotron X-ray technologies are utilized to explore the structural evolution of nanoparticles. We summarize numerous studies concerning X-ray-induced synthesis of gold nanoparticles. Further, we discuss the nuclear growing mechanism—radiolysis and conventional wet synthesis—explored via in situ XAFS analysis. Lastly, we propose the improvement of radiolytic synthesis and the application of in situ XAFS.
