To date, a plethora of electrocatalysts for the Oxygen Evolution Reaction (OER) have been proposed. For evaluating their electrocatalytic behavior determination onset potential in each studied electrolyte is key parameter. Nevertheless, this evaluation becomes particularly problematic first-transition metal catalysts as well by use electroactive collectors (e.g. Ni foams) whose redox peaks over...

Abstract By the example of study AISI 1016 steel corrosion in HCl solution, potentialities various methods for determining currents are studied. The rate without polarization is determined using method measuring ohmic resistance test specimen. It shown that iterative used analysis potentiodynamic curves vicinity potential avoids complications arise when Tafel extrapolation absence pronounced se...

A SnO2 nanocrystallite-based photoanode was prepared using tin (iv) chloride and fructose via a one-pot hydrothermal method, and its structural and morphological properties were studied. Structural observations revealed tetragonal crystals of SnO2, and morphological studies confirmed the presence of spherical nanoparticulates. Furthermore, encapsulating the surface of the SnO2 photoanode (+N719...

Advanced approaches to preparing non-noble-metal electrocatalysts for the hydrogen evolution reaction (HER) are considered to be a significant breakthrough in promoting the exploration of renewable resources. In this work, a hybrid material of MoS2 nanoflowers (NFs) on reduced graphene oxide (rGO) was synthesized as a HER catalyst via an environmentally friendly, efficient approach that is also...

Laccase, a multicopper oxidase, catalyses the four electron reduction of oxygen to water. Upon adsorption to an electrode surface, laccase is known to reduce oxygen at overpotentials lower than the best noble metal electrocatalysts usually employed. While the electrocatalytic activity of laccase is well established on carbon electrodes, laccase does not typically adsorb to better defined noble ...
