Various metal-containing sorbents dispersed in activated carbons, zeolite, and silica have also been proven to be potential materials for CO purification ; however, these are usually associated with higher costs and lower metal density compared to molecular-based systems and MOFs. Given the significant impact of purification processes on capital and operating costs in industry (accounting for 40-70%) and on global energy consumption (accounting for 10-15%) , the establishment of a novel strategy for less-energy-consuming and sustainable chemisorption systems is desirable.
