“…Although ionic liquids and solid materials, such as zeolites, activated carbon, and molecular sieves, are typically used to capture H 2 S, these materials have limitations, such as low capture amounts, corrosiveness, and high processing costs. − To overcome these limitations, researchers have been exploring metal–organic frameworks (MOFs) as an alternative to ionic liquids and solid materials. , MOFs are microporous materials that have properties such as high thermal stabilities, low densities, high specific surface areas, and controllable structures, which render them ideal for gas storage and separation in clean energy applications. , MOFs have numerous gas-adsorption sites, and their structures can be modified to afford multifunctional designs. , Since their discovery by Yaghi et al in 2002, MOFs have been extensively studied as gas-adsorption materials.…”
