Inorganic composite sorbents for water vapor sorption: A research progress

The inorganic composite sorbent provides one of the feasible solutions for water vapor sorption due to large water uptake, high sorption/desorption rate, excellent thermal stability and cycle performance. Additionally, it is also an ideal material for the desiccant air conditioning. This paper reviews inorganic composite sorbents researched in the past two decades, including silica gel-based sorbents, activated carbon-based sorbents and zeolite molecular sieve-based sorbents. Based on a comparative study of such composite sorbents, the paper unrolls a comprehensive picture of the progress thereof, in which the advantages and disadvantages of each sorbent are briefly depicted.
