Bisphenol A (BPA) is identified endocrine-disrupting compounds (EDCs) that is detected in waterresources. The intrinsic properties of nanoclays favor to stimulate the combination of sieving and electrostaticinteraction mechanisms during the removal of BPA using membrane separation. Herein, the synthesisedhydrophilic bentonite-polyaniline (B-PANI) and cloisite 15A-polyaniline (C-PANI) was loadedindividually into polyethersulfone (PES) for fabricating mixed matrix membranes (MMMs). The PANInanoclays was presented in both surface layer and inside pores of nanocomposite membranes at 0.5, 1and 1.5 wt% loading. The results showed the enhancement in surface hydrophilicity for all the membranesin loading of PANI nanoclays. The presence of B-PANI influenced the higher water flux of 82.2Lm-2h1 at 1.5 wt%, indicating hydrophilic property. YBP2 MMM with 1 wt% B-PAN depicted higherBPA rejection efficiency of 77.2 %. B-PANI bestow the MMM with hydroxyl and amine functional groupswhich retard the transport of hydrophobic BPA through the hydrophilic MMM. Further, higher BPA rejectionwas ascribed to the electrostatic repulsion between MMM surface and BPA. The fouling mechanismwas identified by Hermia model that represents YBP2 membrane revealed cake filtration fouling modelwith reversible fouling. This work highlights the feasibility of B-PANI in MMM for BPA removal fromwater.

Nanostructured carbon based materials with unique and tunable properties make them to be utilized forvarious applications in different forms especially for energy and environmental applications. Carbon is adistinctive chemical element which has superior properties such as porous structure, low cost, resistanceto basic and acidic conditions, easy accessibility, low density, good recycling properties, more abundantand ability to combine with other chemical elements in different ways. In this review, we have criticallyassessed the recent developments in carbon based heterostructures for their applications in energy andenvironment. Special consideration has been paid on the applications in dye-sensitized solar cells,hydrogen evolution reaction, oxygen evolution reaction, Li-ion battery, supercapacitor, photocatalysis forthe degradation of organic pollutants, electrochemical/bio sensors and biomedical applications. Finally,the challenges and future developments of carbon based heterostructures for applications in energy andenvironment are also outlined.

Supercapacitors (SCs) has gained an impressive concentration by the researchers due to its advantages such as high energy and power densities, long cyclic life, rapid charge–discharge rates, low maintenance and desirable safety. Hence it has been widely utilized in energy storage and conversion devices. Among the different components of SC, electrodes play a vital role in the performances of SCs. In this review, we present the recent advances in 2-D nanostructured metal nitrides, carbides, and phosphides based materials for SC electrodes. Finally, the electrochemical stability and designing approach for the future advancement of the electrode materials are also highlighted.
