Journal ArticleDOI
Selective Molecular Sieving in Self-Standing Porous Covalent-Organic-Framework Membranes
Sharath Kandambeth,Bishnu P. Biswal,Harshal D. Chaudhari,Kanhu Charan Rout,H Shebeeb Kunjattu,Shouvik Mitra,Suvendu Karak,Anuja Das,Rabibrata Mukherjee,Ulhas K. Kharul,Rahul Banerjee +10 more
TL;DR: Self-standing, flexible, continuous, and crack-free covalent-organic-framework membranes (COMs) are fabricated via a simple, scalable, and highly cost-effective methodology and show long-term durability, recyclability, and retain their structural integrity in water, organic solvents, and mineral acids.
Journal ArticleDOI
Constructing Ultraporous Covalent Organic Frameworks in Seconds via an Organic Terracotta Process
Suvendu Karak,Sharath Kandambeth,Sharath Kandambeth,Bishnu P. Biswal,Bishnu P. Biswal,Himadri Sekhar Sasmal,Himadri Sekhar Sasmal,Sushil Kumar,Pradip Pachfule,Rahul Banerjee,Rahul Banerjee +10 more
TL;DR: A simple route toward the rapid synthesis of highly crystalline and ultraporous COFs in seconds using a novel salt-mediated crystallization approach and the regular COF beads are shown to outperform the leading zeolites in water sorption performance, with notably facile regeneration ability and structural integrity.
Journal ArticleDOI
Interlayer hydrogen-bonded covalent organic frameworks as high-performance supercapacitors
Arjun Halder,Arjun Halder,Meena Ghosh,Meena Ghosh,Abdul Khayum M,Abdul Khayum M,Saibal Bera,Saibal Bera,Matthew Addicoat,Himadri Sekhar Sasmal,Suvendu Karak,Suvendu Karak,Sreekumar Kurungot,Sreekumar Kurungot,Rahul Banerjee +14 more
TL;DR: A redox active and hydrogen bonded COF with ultrahigh stability with outstanding areal capacitance 1600 mF cm-2 (gravimetric 169 F g-1) and excellent cyclic stability without compromising its capacitive performance or Coulombic efficiency is reported.
Journal ArticleDOI
Superprotonic Conductivity in Flexible Porous Covalent Organic Framework Membranes
Himadri Sekhar Sasmal,Harshitha Barike Aiyappa,Siddheshwar N. Bhange,Suvendu Karak,Arjun Halder,Sreekumar Kurungot,Rahul Banerjee +6 more
TL;DR: Attainment of 24 mW cm-2 power density, which is the highest among COFs and MOFs, highlights the possibility of using a COF membrane over the other state-of-the-art crystalline porous polymeric materials reported to date.
Journal ArticleDOI
Ultrastable Imine-Based Covalent Organic Frameworks for Sulfuric Acid Recovery: An Effect of Interlayer Hydrogen Bonding.
Arjun Halder,Suvendu Karak,Matthew Addicoat,Saibal Bera,Amit Chakraborty,Shebeeb H. Kunjattu,Pradip Pachfule,Thomas Heine,Rahul Banerjee,Rahul Banerjee +9 more
TL;DR: These COFs were further converted into porous, crystalline, self-standing, and crack-free COF membranes (COFMs) with extremely high chemical stability for their potential applications for sulfuric acid recovery.
