The composite can be prepared by annealing the MOF at different temperatures (500 degrees C and 600 degrees C), each case exhibiting unique properties in terms of the hydrophobic behaviour and surface area, resulting in specific applicability domains. We highlight the exceptional behaviour of this material as a magnetically separable and recyclable superadsorbent for removal and recovery of environmental pollutants (oil/hydrocarbon and dye/phenol).</p>1 aBanerjee, Abhik1 aGokhale, Rohan1 aBhatnagar, Sumit1 aJog, Jyoti, Prakash1 aBhardwaj, Monika1 aLefez, Benoit1 aHannoyer, Beatrice1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/mof-derived-porous-carbon-fe3o4-nanocomposite-high-performance-recyclable-environmental-001948nas a2200181   4500008004100000245016300041210006900204260000800273300001400281490000600295520122100301100002001522700002101542700001801563700002801581700002901609856012801638       2016                        eng d00a Robust highly flexible all-solid-state micro pseudocapacitor based on ternary oxide CuCo2O4 having ultrathin porous nanowall type morphology blended with CNT0 aRobust highly flexible allsolidstate micro pseudocapacitor based  cOCT  a5159-51640 v13 aIn this work we demonstrate a facile approach to the fabrication of all solid state flexible interdigitated micro pseudocapacitor device using pre-synthesized CuCo2O4 (CCO) ternary metal oxide as the electrode material. The hydrothermally synthesized CCO exhibits a peculiar 3D interconnected aligned porous nanowall type morphology which is highly desirable for storage as well as charge transfer. The device is fabricated using CO2 laser scribing technique and the PVA-H3PO4 gel electrolyte is used as the electrolyte. The as-synthesized CCO as well as its blend with 10 wt.% CNT are examined for the electrochemical performance. CNT blending is shown to reduce the charge transfer resistance dramatically, thereby enhancing the pseudo capacitance. The areal capacitance of 2.29 mF cm(-2) is obtained from the solid state device. Moreover, the CCO-CNT electrode also shows a high stability upto 9000 cycles without a sign of further decay. Importantly, the devices also retain over 65% of their initial capacitance after 1000 large angle (608) bending cycles and 93% of the initial capacitance under 1208 bending condition, thanks to the mechanical flexibility afforded by CNTs without disrupting conducting paths.1 aBasu, Aniruddha1 aBhardwaj, Monika1 aGawli, Yogesh1 aRode, Chandrasekhar, V.1 aOgale, Satishchandra, B.  uhttps://library.ncl.res.in/content/robust-highly-flexible-all-solid-state-micro-pseudocapacitor-based-ternary-oxide-cuco2o401922nas a2200241   4500008004100000245014000041210006900181260000800250300001400258490000700272520108800279653002001367653001901387653001101406653001701417653002101434653002101455100002001476700001901496700001801515700002101533856012601554       2017                        eng d00aG - C3N4 (2D)/CdS (1D)/rGO (2D) dual-interface nano-composite for excellent and stable visible light photocatalytic hydrogen generation0 aG C3N4 2DCdS 1DrGO 2D dualinterface nanocomposite for excellent   cMAR  a5971-59840 v423 a<p>A 2D/1D/2D dual-interface nano-composite configuration in the form of CdS nanorods sandwiched between g-C3N4 and rGO sheets with intimate interfacial contact is synthesized by a facile wet-chemical method and is shown to exhibit excellent photocatalytic H2 generation under visible-light irradiation. In particular, the optimal g-C3N4/CdS/rGO dual-interface nano-composite shows H2 production rate of ∼4800 μmol h-1 g-1, which is almost 44, 11 and 2.5 times higher than that shown by pure g-C3N4 nanosheets, and the g-C3N4/rGO and g-C3N4/CdS single interface heterostructures, respectively. It is shown that the synergic effects involving the band structure match and close interfacial contact, which can accelerate the separation and transfer of photoinduced charge carriers, and the enhanced visible-light absorption together contribute to the impressive photocatalytic performance and photostability of the g-C3N4/CdS/rGO ternary nano-composite system. Specific advantages of a dual-interface triple-composite system over a single interface case(s) are also brought out.</p>10acharge transfer10aDual Interface10aG - CN10aH Generation10aHetero Structure10aNano - Composite1 aTonda, Surendar1 aKumar, Santosh1 aGawli, Yogesh1 aBhardwaj, Monika  uhttps://library.ncl.res.in/content/g-c3n4-2dcds-1drgo-2d-dual-interface-nano-composite-excellent-and-stable-visible-light01817nas a2200181   4500008004100000245012100041210006900162260000800231300001400239490000700253520114300260100002001403700001901423700002101442700001801463700002501481856012901506       2018                        eng d00aG-C3N4/NiAl-LDH 2D/2D hybrid heterojunction for high-performance photocatalytic reduction ofco2 into renewable fuels0 aGC3N4NiAlLDH 2D2D hybrid heterojunction for highperformance phot  cJAN  a2667-26780 v103 a2D/2D interface heterostructures of g-C3N4 and NiAl-LDH are synthesized utilizing strong electrostatic interactions between positively charged 2D NiAl-LDH sheets and negatively charged 2D g-C3N4 nanosheets. This new 2D/2D interface heterojunction showed remarkable performance for photocatalytic CO, reduction to produce renewable fuels such as CO and H-2 under visible-light irradiation, far superior to that of either single phase g-C3N4 or NiAl-LDH nanosheets. The enhancement of photocatalytic activity could be attributed mainly to the excellent interfacial contact at the heterojunction of gC(3)N(4)/NiAl-LDH, which subsequently results in suppressed recombination, and improved transfer and separation of photogenerated charge carriers. In addition, the optimal g-C3N4/NiAl-LDH nanocomposite possessed high photostability after successive experimental runs with no obvious change in the production of CO from CO, reduction. Our findings regarding the design, fabrication and photophysical properties of 2D/2D heterostructure systems may find use in other photocatalytic applications including H-2 production and water purification.1 aTonda, Surendar1 aKumar, Santosh1 aBhardwaj, Monika1 aYadav, Poonam1 aOgale, Satishchandra  uhttps://library.ncl.res.in/content/g-c3n4nial-ldh-2d2d-hybrid-heterojunction-high-performance-photocatalytic-reduction-ofco2
