Abstract

Climate change is causing uneven distribution of rainfall around the world. Artificial rainfall technology provides the possibility of changing regional rainfall and adjusting the distribution of water resources. The most critical part of artificial rainfall technology was the development of cloud seeding catalyst. Among them, AgI has the advantages of high catalytic efficiency and easy spreading operation, making it the most widely used cloud seeding catalyst. However, the inactivation of AgI when exposed to light hinders its application as a catalyst for artificial rainfall. In this paper, a series of experiments and characterization are used to clarify the structure and morphology variation of AgI under illumination. Thereby, the photoinactivation mechanism of AgI cloud seeding catalyst was analyzed. This paper aims to understand and optimize the change process of AgI in cloud seeding and provides a scientific basis and technical guidance for improving the practical application effect of AgI cloud seeding catalysts.

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
