We propose a method to enhance the fuel cell efficiency with the simultaneous removal of toxic heavy metal ions. Carbon monoxide (CO), an intermediate of methanol oxidation that is primarily responsible for Pt catalyst deactivation, can be used as an in-situ reducing agent for hexavalent chromium (Cr (VI)) with reactivating the CO-poisoned Pt catalyst. Using electro-oxidation measurements, the ...

Downsizing the Pt particle to the atomic level in the electro-catalysts is highly desirable to enhance its utilization efficiency in fuel cells. In this study, Pt subnano/nanoclusters were stabilized by the pristine graphene nanosheets (GNSs) derived from chemical vapor deposition and the resulting Pt/GNS hybrids were examined as catalysts for electro-oxidation of alcohols (methanol, ethanol, e...

The complete electro-oxidation of glycerol to CO2 is performed through an oxidation cascade using a hybrid catalytic system combining a recombinant enzyme, oxalate decarboxylase from Bacillus subtilis, and an organic oxidation catalyst, 4-amino-TEMPO. This system is capable of electrochemically oxidizing glycerol at a carbon electrode collecting all 14 electrons per molecule.

Oxygen Reduction Reaction (ORR) performance of iron and nitrogen co-doped porous carbon nanoparticles (Fe-NPC) with various physical and (electro) chemical properties have been investigated. Fe-NPC nanoparticles are synthesized via a facile soft-templating procedure by using Iron (III) chloride hexa-hydrate as iron precursor and aminophenol-formaldehyde resin as both carbon and nitrogen precurs...

In the present study, PtRuCe/MWNTs nanocatalysts synthesized via polyol process technique are applied as anode electro-catalyst in methanol electro-oxidation reaction (MOR). To characterize the nanocatalysts, TEM, XRD, EDS and XPS are investigated. Cyclic voltammetry and choronoamperometry are used to evaluate the electro-catalytic activ...

Electrochemical molecular catalyst screening (EMoCS) has been developed. This technique allows fast analysis and identification of homogeneous catalytic species through tandem catalyst assembly and electrochemistry. EMoCS has been used to study molecular proton reduction catalysts made from earth abundant materials to improve their viability for water splitting systems. The efficacy of EMoCS is...

In the present study, three different structures with preferentially exposed crystal faces were supported on commercial carbon black by the polyol method (nanoparticles (NP/C), nanobars (NB/C) and nanorods (NR/C)). The electrocatalysts were characterized by XRD, TEM, TGA and cyclic voltammetry at three different ethanol concentrations. Considerable differences were found in terms of catalytic e...

The electrolysis of water for substantial production hydrogen and oxygen with very high purity is considered as a potentially practical technology. In the present study, we have fabricated graphene-oxide hybrid zinc-selenide electrocatalyst characterized it using different techniques. XRD analysis confirms phase crystal structure electrocatalyst. Furthermore, elemental arrangement morphology we...

The Cover Feature depicts a schematic soccer game representing two strategies for the radical C-H substitution reaction catalyzed by naphthalene diimides (NDIs): consecutive photoinduced electron transfer (conPET) and an electro (electroPET). A ball (electron) coming from different sources reaches comfortable spectator (the substrate) after passing through players (NDI catalyst). In their Full ...
