the conducting polymer films have been widely applied in the field of electrochemistry owing to their goodstability, permselectivity, unique physical and chemical properties. a novel nano-au/poly (4-aminobenzoicacid) (paba) film modified carbon paste electrode was fabricated for sensitive detection of acetaminophenin this paper. the paba film and nano-au/paba film were characterized by scanning...

The electro-catalytic activity with respect to water oxidation to form molecular oxygen of iron oxyhydroxide thin films on iron support surfaces in aqueous base is described. A mechanism involving iron surfaquo groups is proposed in excellent agreement with the kinetic data. It is shown that the rate determining step of the oxygen evolution reaction depends strongly on the conditions under whic...

The nanocomposites of reduced graphene oxide (rGO) supported zinc tungstate nanoparticles (ZnWO4-NPs) receive considerable attention in electro-catalytic hydrogen evolution reactions (HER) and reveal significantly higher performances than pure ZnWO4-NPs alkaline media (i.e., 0.5 M KOH electrolyte). polarization studies show that the ZnWO4-NPs@rGO exhibit low energy loss good electrode stability...

In recent years, we have experienced extreme climate changes due to the global warming, continuously impacting and changing our daily lives. To build a sustainable environment society, various energy technologies been developed introduced. Among them, harvesting, converting ambient environmental into electrical energy, has emerged as one of promising for variety applications. particular, photo ...

Rapid depletion of fossil fuel and increased energy demand has initiated a need for an alternative energy source to cater for the growing energy demand. Fuel cells are an enabling technology for the conversion of sustainable energy carriers (e.g., renewable hydrogen or bio-gas) into electrical power and heat. However, the hazardous raw materials and complicated experimental procedures used to p...

A heterogeneous dihydrogen (H2) production system has been attained by simply soaking electrodes made from electro-deposited graphene on FTO plated glass in solutions of a cobalt bis(dithiolate) compound. The resulting electrodes are active in weakly acidic aqueous solutions (pH > 3), have relatively low overpotentials (0.37 V versus platinum), show high catalytic rates (TOF > 1000 s(-1)), and ...

Abstract Nitrogen, one of most important elements on the Earth, plays an essential role in shaping modern society. The natural nitrogen looping, however, is insufficient to satisfy high demand large‐scale human activities. To achieve a more sustainable and efficient utilization nitrogen, artificial looping by photo(electro)catalytic processes has been considered as feasible strategy. In this co...
