Engineering of Zirconium based metal-organic frameworks (Zr-MOFs) as efficient adsorbents

Synthesis of porous materials is very attractive due to their various applications in era of water purification. The other advantage is due the structural and functionality of stable MOFs-based porous materials. Metal-organic frameworks (MOFs) are spongy like structures that are composed of transition metals coordinately linked or protected via ligands may be responsible for the active centers and large surface area. In this mini review, we have emphasized the development of water stable Zr-MOFs that have been potentially used as emerging adsorbents for cationic and anionic contaminants in water. The main focus of this review is on the detail study of stability as well as the factors affecting the stability of Zr-based MOFs, including the adsorbent capacities, thermodynamics and kinetic studies. Moreover we have discussed the introduction of metal ions to organic linkers having more replaceable atoms that makes them more reliable adsorbents than other conventional adsorbents. Of note the Zr-MOFs exhibit as an emerging platform for the cost effective, eco-friendly approach and interesting adsorbent-adsorbate interactions for water treatment.
