Conductivity and transport properties of a cost-effective and environment friendly chitosan based solid biopolymer electrolytes which form mechanically robust thick film, have been reported here. A maximum ionic conductivity of ∼ 10 ⁻⁴ S/cm has been achieved by optimizing the concentrations of the salt (LiClO 4 ) and the plasticizer (EC) in the bio...
Iron- and steelmaking cause ~7% of the global CO2 emissions, due to the use of carbon for the reduction of iron ores. Replacing carbon by hydrogen as the reductant offers a pathway to reduce emissions. However, production of hydrogen using renewable energy will remain a bottlenecks, because making the annual crude steel production of 1.8 billion to...
To fabricate cost‐effective anode catalysts for direct ethanol fuel cells (DEFC), Pd and a series of bimetallic PdxNi100‐x alloy nano catalyst has been synthesized by adhering toclassical wet chemical synthetic procedure. External capping agents have not been employed for stabilization of the nanoparticles. Several physicochemical characterizations...

alloy nanoparticles of various compositions were synthesized by one-pot coreduction of respective precursors with hydrazine for use in the anode catalysis of oxidation of butan-1-ol in alkali. The as-synthesized catalyst materials were characterized by microscopic, spectroscopic, and dif...
Iron- and steelmaking cause ∼7% of the global CO2 emissions, due to the use of carbon for the reduction of iron ores. Replacing carbon by hydrogen as the reductant offers a pathway to massively reduce these emissions. However, the production of hydrogen using renewable energy will remain as one of the bottlenecks at least during the next two decade...
Highly stable catalytically active polyvinyl alcohol supported Pd nanoparticles (Pd NPs) are synthesized and used as catalysts in reduction of 4-nitrophenol in aqueous phase by sodium borohydride as reducing agent. The as—synthesized Pd NPs are characterized with the help of UV—vis. absorption spectroscopy, X—ray diffraction (XRD), transmission ele...
Different sets of nickel nanoparticles with confined average diameter in the range: 9.4–13.7 nm are synthesized by varying different parameters of wet chemical method to investigate the effects of such parameters on anode catalysis in oxidation of butan-1-ol in aqueous alkali. The structure and morphology of the synthesized nanoparticles and the ro...
Platinum (Pt) nanoparticles of varying average diameters decorated on exfoliated reduced graphene oxide (Pt/rGO) of various functionalities have been synthesized by monitoring the temperature of co-reduction of Pt IV and GO. The as-synthesized composites are characterized by X-ray diffraction, spectroscopic, thermo gravimetric and microscopic studi...
A film of the polymer of intrinsic microporosity PIM‐7 is coated onto a glassy carbon electrode and the resulting effects on electron transfer reactions are studied for three different types of processes: (i) aqueous solution based, (ii) solid state surface immobilised, and (iii) electrocatalytic processes on electrodeposited palladium. The effects...
Size controlled synthesis of palladium nanoparticles of varying average diameter ranging from 8.1 to 21.3 nm, was executed by controlling the time of reflux of the facile reduction of PdCl2 in a single pot using citric acid as reducing agent in presence of the steric stabilizer poly vinyl alcohol in water. The as synthesized nanomaterials were anal...
Palladium nanoparticles with varying particle diameter (6.9–25.1 nm) have been synthesized by single-pot wet chemical technique in presence of poly vinyl alcohol by controlling the duration of reflux. The resulting nanoparticles have been dip-coated on Ni-foil, followed by determination of kinetic parameters of the anode-catalysts in reference to a...

In the search for commercial anode materials for direct methanol fuel cells, nanoparticles of Pt, Ni, and PtxNiy alloys have been synthesized via one pot reduction of the respective pure and mixed metal precursors at 60 °C without adding any capping agent. The obtained Ni-Pt nanoalloy is stable in dispersion and powder form. The X-ray diffraction,...
