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 work reports the synthesis and characterization of ternary nanoalloy catalysts silver, bismuth, rhenium from alkaline solutions containing L–cysteine as a complexing agent sodium borohydride reducing agent. UV–Vis spectra dynamic light scattering (DLS) analyses obtained colloids were performed. Additionally, high-resolution transmission electron microscope (HR–TEM) analysis assisted former ...

Developing sustainable and clean energy technology is critial to address the current environmental crisis. As an carrier, hydrogen has been getting attention due its abundance, high density, zero carbon emission. Due difficulty of storage transport, electro-oxidation ammonia shows great potential for renewable since it satisfies both supply protection as a carbon-free fuel with content. However...

Using the binding energy of OH* and CO* on close-packed surfaces as reactivity descriptors, we screen bulk and surface alloy catalysts for methanol electro-oxidation activity. Using these two descriptors, we illustrate that a good methanol electro-oxidation catalyst must have three key properties: (1) the ability to activate methanol, (2) the ability to activate water, and (3) the ability to re...

In the present study, a type of graphitic mesoporous carbon (denoted as GMC) is synthesized and its structural properties were characterized by nitrogen physisorption isotherms, transmission electron microscopy and Raman spectroscopy. According to BET and BJH methods, the specific surface area (SBET) and the average pore diameter of GMC are estimated to be 720 m2/g and 3.4 nm, respectively....

In this work, CuO nanoparticles (CuO NPs) was prepared by a simple and green method using Rosmarinus officinalis extract containing phenolic constituents as both the chelating and the stabilizing agents. CuO nanoparticles/polyorthoaminophenol composite (CuO NPs/POAP) as electro-active electrodes for electrocatalytic oxidation of methanol with good uniformity are prepared by electropolymerizatio...

Isatins, derivatives of indole, represent important class of compounds belonging to nitrogen heterocycles. These compounds comprise synthetically vital substrates that are used as precursors for drug synthesis and raw materials for heterocycles etc. Research in this group of compounds has engrossed interest among scientific community in recent and past as Isatins are known to possess immense bi...

A facile and efficient molecularly imprinted polymer (MIP) recognition element of electrochemical sensor was fabricated by directly electro-polymerizing monomer o-phenylenediamine (oPD) in the presence of template quinoxaline-2-carboxylic acid (QCA), based on one-step controllable electrochemical modification of poly(pyrrole)-graphene oxide-binuclear phthalocyanine cobalt (II) sulphonate (PPY-G...
