Novel magnetic HS--adsorptive nanocomposite photocatalyst (rGO/CoMn2O4-MgFe2O4) for hydrogen fuel production using H2S feed

Auto combustion synthesis using grapefruit extract: photocatalyst and magnetic MgFe2O4-PbS nanocomposites

Magnesium ferrite (MgFe2O4) as a core magnetic nanostructure was synthesized via auto combustion method by using grapefruit extract as a biocompatible and cost-effective material. Then flower and star-like PbS were synthesized using thioglycolic acid as a sulfur source without using any chemical template. After that for preparation of magnetic and photocatalyst MgFe2O4-PbS nanocomposites, lead ...

Adsorptive removal of azide ion from aqueous solutions using modified activated carbon magnetic nanocomposite

In this work, the activated carbon/magnetic Fe3O4 nanocomposite was synthesized and characterized by TEM and XRD measurements. This magnetic nanocomposite was modified with cetylpyridinium chloride (CPC) and thus used as a new adsorbent for removal of azide ion from an aqueous solution. In an aqueous solution of azide ion, the adsorption capacity was evaluated using both the Langmuir and Freund...

Towards efficient solar hydrogen production by intercalated carbon nitride photocatalyst.

The development of efficient photocatalytic material for converting solar energy to hydrogen energy as viable alternatives to fossil-fuel technologies is expected to revolutionize energy shortage and environment issues. However, to date, the low quantum yield for solar hydrogen production over photocatalysts has hindered advances in the practical applications of photocatalysis. Here, we show th...

Novel PVA/La2Ce2O7 hybrid nanocomposite membranes for application in proton exchange membrane fuel cells

Proton exchange membrane fuel cells (PEMFCs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. In this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/La2Ce2O7 (PVA-LC) with the aim of increasing the water uptake and proton conductivity. Glutaraldehyde (GA) was used as cross linking agent ...
