Our group has judiciously designed framework structures by incorporating polar functional groups like -F, -OH, -NH2 on the pore surface which can effectively interact with the quadrupolar CO2 molecules and subsequently affect the adsorption selectivity. Our group has shown hydrophobic MOFs based on fluorinated linkers are more effective in selective capture of CO2 which is of paramount importance for separation of CO2 from flue gas mixture. \nTaking a step further to efficiently convert CO2 into valuable feedstock, enabling sustainable chemical transformations, our research group have unveiled a number of photocatalytic strategies by harnessing solar energy. This has been accomplished through various approaches: (i) Tuning the pristine MOF\/POP\/CPG catalyst structure at the molecular level, (ii) Introduction of molecular catalysts in the framework by post-synthetic modification or guest encapsulation and (iii) Heterostructure formation of MOF\/POP\/CPG with other functional materials for efficient photochemical CO2 reduction.

Our group has developed a binary (aminopropyl-functionalized magnesium phyllosilicate or aminoclay, and MOF) and ternary (aminoclay, graphene oxide, and MOF) nanocomposites, highlighting their water storage and harvesting capabilities in indoor environments. Furthermore, we have &nbsp;explored the dynamics of water collection by varying ambient humidity, release temperature, and on-demand sorption\/desorption cycles under typical indoor conditions without relying on solar irradiation.<\/span><span style=\"box-sizing: inherit;\"><strong><o:p style=\"box-sizing: inherit; padding: 0px; margin: 0px; overflow-wrap: break-word;\"><\/o:p><\/strong><\/span><\/span><\/p><p class=\"MsoNormal\" style=\"box-sizing: inherit; margin: 0px 0px 0cm; padding: 0px; overflow-wrap: break-word; text-align: justify; line-height: normal;\"><span style=\"box-sizing: inherit; padding: 0px; margin: 0px; overflow-wrap: break-word; font-size: 12pt; color: black;\"><strong>&nbsp;<\/strong><\/span><\/p><\/span><p class=\"MsoNormal\" style=\"box-sizing: inherit; margin: 0px 0px 0cm; padding: 0px; overflow-wrap: break-word; text-align: justify; line-height: normal;\"><span style=\"box-sizing: inherit; padding: 0px; margin: 0px; overflow-wrap: break-word; font-size: 12pt; color: black;\"><\/span><\/p><p class=\"MsoNormal\" style=\"box-sizing: inherit; margin: 0px 0px 0cm; padding: 0px; overflow-wrap: break-word; color: rgb(111, 115, 128); font-family: Poppins, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; text-align: justify; line-height: normal;\"><span style=\"box-sizing: inherit; padding: 0px; margin: 0px; overflow-wrap: break-word; font-size: 12pt; font-family: Cambria, serif; color: black;\"><\/span><\/p><p class=\"MsoNormal\" style=\"box-sizing: inherit; margin: 0px; padding: 0px; overflow-wrap: break-word; color: rgb(111, 115, 128); font-family: Poppins, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: rgb(255, 255, 255); text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; text-align: justify; line-height: normal;\"><\/p><p class=\"MsoNormal\" style=\"text-align:justify;line-height:normal\"><span style=\"text-align: start; font-family: Tahoma; color: rgb(0, 41, 102);\"><\/span><\/p><p class=\"MsoNormal\" style=\"margin-bottom: 0cm; text-align: justify; line-height: normal;\"><strong><span style=\"font-size: 12pt; font-family: Cambria, serif; color: black;\">(Related publications from the group:&nbsp;<em>Adv.
