Coal gangue is a typical waste produced during coal mining and washing. Synthesis of zeolites via coal gangue can contribute to resource recycling and environmental protection. In this study, high-silica SSZ-13 was synthesized by one-step hydrothermal synthesis from coal gangue without the traditional pretreatment methods of high-temperature roasting and alkali melting, making it more
