Electrochemical water splitting is one of the most economical and sustainable methods for large-scale hydrogen production. However, the development of low-cost and earth-abundant non-noble-metal catalysts for the hydrogen evolution reaction remains a challenge. Here we report a two-dimensional coupled hybrid of molybdenum carbide and reduced graphene oxide with a ternary polyoxometalate-polypyr...

An attempt has been made to prepare Graphene-Fe 3 O 4 -polypyrrole (GFP) based ternary material as an electrode for pseudocapacitors. The GFP nanocomposite materials were fabricated well by a simple hydrothermal route. as-prepared characterized conventional analytical techniques. Polypyrrole helps the Fe nanoparticles anchor on graphene oxide surface and inhibits aggregation of sheets particles...

In this research, we developed a facile method for the synthesis of silver chloride: polypyrrole (AgCl: PPy) nanocomposites with enhanced structural, thermal, optical, and conducting properties. Polypyrrole monomer was in-situ doped varying weight percentages assynthesized Ag nanoparticles by following simple chemical oxidation polymerization technique to form AgCl: PPy nanocomposites. The AgCl...

Abstract Nanocomposite of magnetic Fe 3 O 4 nanoparticles and polypyrrole was prepared under sonication by a new chemical polymerization method during which acted both as pyrrole oxidant component in the composite material. Synthesis this nanocomposite carried out aqueous solution acidified to pH 2, prerequisite for formation these types material facilitate oxidation nanoparticles. In way, two ...

Amidst the COVID-19 pandemic, environmental problems such as energy crisis, global warming, and contamination from pathogenic micro-organisms are still prevailed strongly demanded progress in high-performance storing anti-microbial materials. The nanocomposites materials that have earned large interest owing to their promising applications for countering issues related sustainable a flourishing...

Environmental hazard caused due to the release of dyes in effluents is a concern in many countries. Among the various methods to combat this problem, Advanced Oxidation Process, in which semiconductor photocatalysts are used, is considered the most effective one. These materials release Reactive Oxygen Species (ROS) such as hydroxyl radical and superoxide in suspension that degrade the dyes int...

This article reports an amperometric glucose biosensor based on a new type of nanocomposite of polypyrrole (PPY) with p-phenyl sulfonate-functionalized single-walled carbon nanotubes (SWCNTs-PhSO3-). An environmentally friendly functionalization procedure of the SWCNTs in the presence of substituted aniline and an oxidative species was adopted. The nanocomposite-modified electrode exhibited exc...
