Abstract: Pickering emulsion, an emulsion stabilized by colloidal solid particles at the water-oil interface, is a highly intriguing subject in scientific research, daily life, and industrial production. This paper aims to demystify the concept of “Pickering emulsion”. It delves into the fundamental principles, formation mechanisms, preparation techniques, laboratory findings, and applications in the field of photocatalysis. By doing so, it provides college students, teenagers, elementary school students, and even the general public with an opportunity to discover the beauty and wonders of chemistry through the lens of Pickering emulsion.

Key words: Pickering emulsion, Contact angle, Photocatalysis, Science popularization experiment
