Nanoporous graphene own high surface area and unique structural physical properties due to nano-sized pores in nanosheet. has been modified by the introduction of functional groups, doping, or nanoparticle modification applied for nanocomposites. The overview basically highlights design, properties, potential functionalized nanoporous derived nanocomposites advanced membranes (desalination/gas/oil separation), thermal management, electrocatalysts, micro-supercapacitors. According literature, pore size neat is 3–11 Å hydroxyl also had nanopore <10 Å. Functionalized revealed 100% salt rejection, while 89% rejection altered properties. Both gas permeance ∼103–105 GPU towards separation CO2, CH4, N2, etc. Few attempts on micro-supercapacitor like molybdenum disulfide resulted volumetric capacitance 55 F cm−3 retention 82%. Forthcoming research may overcome design/performance challenges leading superior features large-scale utilizations.

Abstract Brookite TiO 2 is a metastable crystalline phase, which difficult to prepare manually. In this study, brookite with controllable morphology was synthesized by simple hydrothermal method. The prepared complete rice‐like granular particle smooth surface and sharp edges at the tip of both ends. And diameter an individual approximately 200 nm. Then, improve photocatalytic degradation performance , we Bi O 3 /brookite nanocomposites. After composite, phase did not change, still maintained high purity crystallinity. nanoparticles were dispersed on forming heterogeneous structures in close contact. nanocomposite exhibited significantly higher rate ofloxacin (20 mg L −1 ) under visible light (300 W Xenon lamp, λ ≥ 400 nm) compared pure . activity 5 mol% best, OFX reached 90.7%. enhancement nanocomposites attributed formation heterojunction, accelerated photogenerated charge‐hole separation. This study provided theoretical support for efficient pollutants.

Abstract Acetone is a common solvent which highly used in laboratory based experiments and industrial products. This valuable organic molecule synthesized by catalytic conversion reactions. A catalyst said to be very useful if it efficient, economical eco‐friendly In this regard; for the first time, less toxic easily supramolecular compound, that is, p ‐sulfonatocalix[4]arene ( SC)‐based was fabricated functionalized with TiO 2 nanoparticles (TiO ‐ SC). The characterization of SC carried out different analytical techniques such as Fourier‐transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), scanning electron microscope (SEM), energy‐dispersive (EDS) transmission microscopy (TEM). nanocomposites were heterogeneous isopropyl alcohol (IPA) into acetone. For study, IPA, NaBH 4 , mixed together flask, mixture stirred at room temperature activity monitored via UV–vis spectroscopy. On spectrum, characteristic absorption band acetone observed 265 nm. complete IPA within 35 40 s. Quantitative analysis SC) also performed using various amounts range 0.1 0.5 mg, showed approximately 100% Moreover, reusability test performed, proved an efficient because poisoning negligible, makes more than other reported catalysts ecofriendly no hazardous used.
