Vacuum hydrogen annealing of TiO<sub>2</sub> leads to increased visible light absorption. The origin thereof was revealed by <italic>ab initio</italic> calculations and X-ray photoelectron spectroscopy.
Density functional theory (DFT) calculations were performed to study the mechanism of carbon dioxide (CO2) reduction monoxide (CO) and methanol (CH3OH) on CeO2(110) surface. CO2 dissociates CO interacting with oxygen vacancy reduced ceria The atom heals site regenerates stoichiometric surface via a redox intrinsic activation reaction energies 259.2 238.6 kJ/mol, respectively. Lateral interaction vacancies studied by generation two per unit CeO2 Compared single isolated vacancy, dissociation...
Formation of the NiCo2O4 (NCO) nanoparticle with simultaneous reduction GO and growth MoS2 by a two step hydrothermal process results in 2D RGO-MoS2 (R-MoS2) cocatalyst layer intimate interfacial contact NCO. The phase purity, chemical coupling morphology synthesized materials are established through X-ray diffraction, Raman photoelectron spectroscopy studies. ternary composite, RGO-MoS2-NiCo2O4 (RM-NCO), shows excellent electrocatalytic performance toward solar driven water splitting 3.08%...
Reduced graphene oxide (RGO)-supported bismuth ferrite (BiFeO3) (RGO-BFO) nanocomposite is synthesized via a two-step chemical route for photoelectrochemical (PEC) water splitting and photocatalytic dye degradation. The detailed structural analysis, coupling, morphology of BFO- RGO-supported BFO are established through X-ray diffraction, Raman photoelectron spectroscopy, high-resolution transmission electron microscopy studies. modified band structure in RGO-BFO obtained from the UV-vis...
This paper demonstrates a new and simplified configuration for capillary electrophoresis-amperometric detection (CE-AD) using microfluidic chip incorporating inexpensive wax printing screen based methods then used electrophoretic separation simultaneous in-channel amperometric of three clinically relevant neurochemicals in single run without any decouplers. Detection e.g., dopamine, epinephrine serotonin is crucial early prediction neurological disorders including Parkinson's, Alzheimer's,...
To achieve sustainable production of H2 at ambient temperature, highly active and stable electrocatalysts are the key to water splitting technology commercialization for hydrogen oxygen replace Pt IrO2 catalysts. Herein, a modified interface palladium (Pd) reduced graphene oxide (RGO)-supported molybdenum disulfide (MoS2) prepared by solvothermal followed chemical reduction method is established, in which abundant interfaces formed. The phase structure, composition, coupling, morphology...
Abstract Advanced and sustainable energy storage technologies with tailorable electrochemically active materials platform are the present research dominancy toward an urgent global need for electrical vehicles portable electronics. Moreover, intensive efforts given to screen widely available low‐cost a focus achieve superior electrochemical performance fabrication of devices. Transition metal‐based sulfides have prodigious technological credibility due their compositional‐...
Several methods (e.g., UV/H2O2 oxidation, adsorption, flocculation−precipitation) are normally employed to remove dye from water. A new technique based on liquid/liquid extraction using reverse micelles is proposed whereby recovery of solvent and reuse possible. Experiments were conducted by mixing a known quantity in aqueous phase solvent-containing surfactants simple mixer. The separation phase, containing encapsulated micelles, due gravity results removal different ionic dyes eosin...
