This study presents a novel approach to decontaminate ferrocyanide‐contaminated wastewater. The work effectively demonstrates the use of bimetallic Mo/Zr‐UiO‐66 as a super‐adsorbent for rapid sequestration of Prussian blue, a frequently found iron complex in cyanide‐contaminated soils/groundwater. The exceptional performance of Mo/Zr‐UiO‐66 is attributed to the insertion of secondary metallic sites,...
A new method based on scanning atmospheric plasma for an ultrafast reduction of graphene oxide (GO) and preparation of highly conductive graphene films and patterns is presented. This simple method is shown to provide a direct and scalable fabrication of graphene films on flexible and shaped substrates with a variety of patterns for broad applications. An effective and ultrafast (∼60 s) reduction...
The rhodamine based receptor, P2 has been developed for the detection of environmentally hazardous Hg2+ ions with a limit of detection, 1.5×10−6M. The P2 showed a significant colour change from colourless to pink upon binding with Hg2+ ions. As a result, a new peak at 533nm was observed in UV–vis spectroscopy which was attributed to spirolactum ring opening followed by through bond energy transfer...
We report a green approach for synthesis of graphene–carbon nanotube aerogels with three dimensional (3D) interconnected networks prepared from natural graphite rocks. A one-step reaction under the synergic effects of the reduction of graphene oxide (GO) sheets and acid treated carbon nanotubes (CNTs) by ferrous ion is employed eliminating the use of harsh chemicals for the reduction of GO. CNTs are...
A simple and green chemistry approach for the preparation of reduced graphene oxide nanosheets through the reduction of graphene oxide (GO) using non-aromatic and thiol-free amino acids as the reductant was successfully demonstrated. l-Aspartic acid and valine amino acids were used as models to prove that the reduction method is generic to other amino acids. The significance of the proposed method...
