Abstract Noble metal (Pt, Ru and Pd) substituted Mn3O4 catalysts have been synthesized in this work by a sonochemical route. The catalysts were characterised by XRD, XPS, TEM, H2-TPR and BET surface area analyser and the activity of these catalysts was tested towards low temperature water gas shift reaction (WGS) and CO oxidation reaction. It was observed that these catalysts have the tetragonal crystalline structure of Mn3O4 and the average particle size was found in the range of 12 nm–22 nm. H...

Abstract Due to the limited access to safe drinking water, there is an emerging need to have a quick water decontamination strategy wherein all the major contaminants of water like dyes, organic compounds, and pathogenic bacteria can be removed using a sustainable approach. Herein, we introduce a facile method to strongly couple photocatalytic dual active AgBiO3 (AB) (light and dark active) onto a membrane consisting of Polyvinylidene fluoride (PVDF) and Poly (butylene succinate-co-adipate) (PBS...

Abstract Recently perovskite materials have received extensive attention for dry reforming of methane (DRM) reaction due to their stable ordered crystalline structure. In this work, materials with ionic substitutions of Ru, Pt, and Pd in LaAlO3 perovskite were synthesized using solution combustion synthesis route. The characterizations of catalysts were carried out by XRD, TEM, XPS, STEM, and BET surface area analyser. H2-TPR was performed to examine the strong metal support interaction between ...

Abstract The repercussions of the miniaturisation and augmentation of modern electronics and telecommunication are the unwanted interferences that come along with it. In the search for a good EMI shield, nanotechnology has come a long way from metal-based EM wave reflector to now lightweight polymeric EM wave absorbers. In this study, we have developed a unique heterostructure by combining the electronic properties of MWNTs, “flower-like” MoS2, magnetic properties of Fe3O4 and graphene oxide (GO...

Nanodelivery is a well-known and efficient strategy andherein, we attempted to mimic this strategy using graphene-based nanoscrolls containing metal–organic frameworks (Zn3(BTC)2MOF) for efficient capture of heavy metal ions and inactivate bacterial cells in water. Zn3(BTC)2 and graphene scrolls have been used in different fields independently, yet the potential scope of these materials is unexplored. Mimicking metamorphosis of a caterpillar was adapted to design deliverable nanoscroll-encapsula...

Abstract PVDF, one of the most versatile fluoropolymers, is inert and is difficult to functionalize using conventional approaches. Herein, we attempted a facile and one-pot modification of PVDF via ozonization process. The ozone treated PVDF facilitates in harnessing suitable functional moieties. Using this strategy, two copolymers were designed to achieve crystalline-amorphous and crystalline-crystalline grafts. Their effects on phase transformation, dielectric and piezoelectric behaviors of PV...

Visible light responsive semiconductor-based photocatalysis is known to be an efficient method for the disinfection of bacterial cells. Here, we address the issue of aqueous contamination by persistent pollutants such as antibiotics and antibiotic resistant bacteria (ARB) from an innovative angle. Simultaneous degradation of an antibiotic (chloramphenicol) and antibiotic resistant bacteria (chloramphenicol resistant E. coli) is performed to observe the effect of the presence of antibiotic in the...

Recent advancements in electronics and telecommunication require materials with excellent resiliency and sustainability in order to extend their lifetime. Keeping this in mind, we developed a sustainable multifunctional nanocomposite by combining the shape memory assisted self-healing (SMASH) capability of “mussel-inspired” dopamine functionalized polyurethane (PU) with synergistic electromagnetic interference (EMI) shielding capabilities from multiwalled carbon nanotubes (MWNTs) and ferrite dop...
