High-throughput study of X-ray-induced synthesis of flower-like Cu_(x)O

Cu_(x)O with flower-like hierarchical structures has attracted significant research interest due to its intriguing morphologies and unique properties.The conventional methods for synthesizing such complex structures are costly and require rigorous experimental conditions.Recently,the X-ray irradiation has emerged as a promising method for the rapid fabrication of precisely controlled Cu_(x)O shapes in large areas under environmentally friendly conditions.Nevertheless,the morphological regulation of the X-ray-induced synthesis of the Cu_(x)O is a multi-parameter optimization task.Therefore,it is essential to quantitatively reveal the interplay between these parameters and the resulting morphology.In this work,we employed a high-throughput experimental data-driven approach to investigate the kinetics of X-ray-induced reactions and the impact of key factors,including sputtering power,film thickness,and annealing of precursor Cu thin films on the morphologies of Cu_(x)O.For the first time,the flower-like Cu_(x)O nanostructures were synthesized using X-ray radiation at ambient condition.This research proposes an eco-friendly and cost-effective strategy for producing Cu_(x)O with customizable morphologies.Furthermore,it enhances comprehension of the underlying mechanisms of X-rayinduced morphological modification,which is essential for optimizing the synthesis process and expanding the potential applications of flower-like structures.
