Activated alumina, traditionally known for its role in water treatment and catalytic processes, is now expanding its applications into innovative sectors such as hydrogen purification, carbon capture, and clean agriculture. The material's efficiency in removing impurities like moisture and sulfur compounds makes it crucial in ensuring high-purity hydrogen for fuel cells and other clean energy applications. In carbon capture and storage (CCS) technologies, activated alumina's adsorption capabilities help capture CO2 emissions from industries, aiding in meeting international climate goals. Its role in air purification is also significant, as it is being used in commercial air purifiers and personal protective equipment to remove volatile organic compounds (VOCs) and particulate matter from the air, improving indoor air quality in various environments. The increasing demand for sustainable and energy-efficient technologies is driving the market dynamics supporting the growth of activated alumina in these emerging industries.
