One bottleneck hampering the widespread use of fuel cell vehicles, in particular of proton
exchange membrane fuel cells (PEMFCs), is the high cost of the cathode where the oxygen …

Fuel cells make use of electrochemical reactions to produce electricity and majority of the
devices have almost no carbon emissions. These devises, and other environmentally …

Abstract Hematite (α-Fe 2 O 3) nanoparticles (NPs) was biosynthesized using Vernonia
amygdalina (V. amygdalina) leaves extract and Fe (NO 3) 3. 9H 2 O precursor and …

Magnetic photocatalyst-based dye degradation under visible light is a promising approach
due to the ease of catalyst separation and recycling provided the catalyst is robust and cost …

The oxygen reduction reaction (ORR) is the rate-limiting reaction in the cathode side of fuel
cells. In the quest for alternatives to Pt-electrodes as cathodes in ORR, appropriate transition …

Bimetallic oxide/carbon nanomaterials hybrids were chemically synthesized and fully
characterized by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) …

In this work, porous spinel Co 3 O 4 nanoparticles were synthesized through solution
combustion. Initially, the effect of calcination on the morphology, phase composition, and …

Fe-doped carbon xerogels with a highly developed graphitic structure were synthesized by a
one-step sol-gel polymerization. These highly graphitic Fe-doped carbons are presented as …

TiO 2 is a low-cost and biocompatible material with high oxidizing ability. However, their
photocatalytic activity is limited to UV light irradiation. In this research, for the first time, a …

Hybrid nanocomposites of bacterial cellulose (BC) and magnetic iron oxide nanoparticles
(NPs) are of interest due to their potential for novel applications. Magnetic NPs are typically …
