Electrochemical conditioning via chronopotentiometry (CP) and cyclic voltammetry (CV) is essential for the activation of oxygen evolution reaction (OER) electrocatalysts. While many reports have activated OER electrocatalysts using either CP or CV, inherent differences between these two electrochemical methods electrocatalytic materials yet to be explored. Here, we investigate effects CV on a Ni-based precatalyst substrate in Fe-purified Fe-unpurified KOH electrolytes by employing (i) Ni...
Alkaline water electrolysis, a promising technology for clean energy storage, is constrained by extrinsic factors in addition to intrinsic electrocatalytic activity. To begin compare between catalytic materials electrolysis applications, these must first be understood and controlled. Here, we modify electrode properties study the effects of bubble release examine how surface design impact performance electrolysis. We fabricate robust cost-effective electrodes through sequential...
This paper presents new data on core-scale wettability alteration of carbonate porous media with FM concentrations up to 30 wt % in NaCl brine. Experimental from Amott tests, core floods, calcite dissolution experiments, and zeta potential measurements were analyzed mechanistically understand the observed experiments. Static tests showed that degree increased increasing concentration brine, even an initially neutral pH. For example, calcium solution was 15.9 times greater than brine initial...
Biomimetic sulfur-deficient indium sulfide (In2.77S4) was synthesized by a template-assisted hydrothermal method using leaves of Mimosa pudica as template for the first time. The effect this in modifying morphology semiconductor particles determined physicochemical characterization, revealing an increase surface area, decrease microsphere size and pore volume density samples with template. X-ray photoelectron spectroscopy (XPS) analysis showed presence organic sulfur (SO/SC/SH) oxide species...
Conventional Carbon Capture and Storage (CCS) operations use the direct injection of CO2 in a gaseous phase from surface as carbon carrier. Due to properties under reservoir conditions with lower density viscosity than situ brine, flux is mainly gravity-dominated. moves toward top accumulates below seal, thus reinforcing risk possible leakage through unexpected hydraulic paths (e.g., reactivated faults, fractures, abandoned wells) or sites without an effective sealing caprock. Considering...
Transition metal borides, carbides, pnictides, and chalcogenides (X-ides) are a new class of oxygen evolution reaction (OER) electrocatalysts, which have become relevant topic for electrocatalytic energy conversion storage research. This is because their earth abundance, high electrical conductivity, resultant OER performance. Furthermore, some X-ide electrocatalysts demonstrate various degrees oxidation resistance under potentials due to differences in chemical composition, crystal...
