This review delves into its innovative applications, showcasing how mechanochemical techniques like ball milling enable precise control over material properties, including nanostructuring, particle size reduction, and defect engineering. These advancements have paved the way for catalysts with enhanced activity, selectivity, and stability, which are crucial for emerging industrial processes such as CO2 reforming, hydrogenation, and oxidation reactions. Despite its ground-breaking potential, challenges related to mechanistic understanding, industrial scalability, and cross-laboratory reproducibility persist. This review emphasizes that integrating advanced in-situ characterization techniques and computational modeling is vital for overcoming these barriers. By doing so, mechanochemistry can be firmly positioned as a cornerstone for future innovations in sustainable catalyst design and green chemical manufacturing.The support provided by Interdisciplinary Research Center for Refining and Advanced chemicals, King Fahd University of Petroleum & Minerals through the project No. INRC2519 is acknowledged
