Oxygen vacancies or defects play a significant role in improving the intrinsic activities of bimetallic hydroxides towards oxygen evolution reaction (OER); however, their rational design and preparation remain great challenge. In this study, vacancy-rich amorphous porous nickel iron hydroxide nanolayers supported on carbon paper (NiFe(OH)x/CP) are rationally prepared through facile approach involving sequential electrochemical deposition Prussian blue (PB) nanocrystal layer Ni(OH)x followed...
A Mo-Doped NiCu electrocatalyst was fabricated <italic>via</italic> a one-step electrodeposition process on Ti substrate as an efficient nonprecious catalyst for the HER.
ABSTRACT A terpolymer comprising of sodium styrene sulfonate (SSS), n ‐methylol acrylamide (HAM), and acrylic acid (AA) was synthesized by aqueous free radical copolymerization evaluated as fluid loss additive (FLA) in oil well cement. In this article, HAM is first introduced the preparation FLA an environment‐friendly monomer, which effectively improves adhesion control terpolymer. The experimental synthesis conditions were optimized orthogonal experiments. molecule weight determined gel...
Degrees for capturing photogenerated holes by residual chemically-adsorbed Cl as donators and electrons increased amount of adsorbed O2 receptors after H3BO3 modification in rutile nanorods are quantitatively controlled based on the surface photovoltage measurements, suggesting that is dominant compared to capture colorless pollutant degradation.
The cement slurry is an important lost circulation material. However, as oil and gas exploration continues toward deeper stratum, the majority of conventional retarders are insufficient at these depths. This research identified a synthetic high-temperature copolymer retarder potential replacement product, containing sodium styrene sulfonate (SSS)/itaconic acid (IA)/N-vinylcaprolactam (NVCL). By analyzing effects monomer mass ratios, initiator concentration, reaction temperature, pH value...
A Ni/Fe hydroxide electrocatalyst was fabricated via a simple and easily controlled method by combining anodic fluoridation cyclic voltammetry (CV) treatment as an efficient catalyst for the OER.
Summary Seismic data in complicated structures have low signal-to-noise ratio and strong lateral variable velocities, it is difficult to obtain the accurate subsurface images. The full-azimuth local angle domain prestack depth migration applies all wavefield within aperture build a at imaging point. It retains azimuth information of values different propagation directions, which can more accurately reflect underground points. Specular weighted function constructed using generated directional...
Summary In Western China, the surface structure is very complex and terrain fluctuates severely. There are high-speed rock formation exposed thick loess covered, at same time, thickness velocity of low-velocity zone vary drastically, seismic energy absorbed attenuated seriously, so there a serious static problem. Tomographic inversion technology has obvious advantages in solving However,the models obtained from first break information different offsets quite under conditions. Therefore,...
