The production of hydrogen through electrochemical water splitting driven by clean energy becomes a sustainable route for utilization energy, while an efficient evolution reaction (HER) electrocatalyst is required to achieve high conversion efficiency. Nickel phosphides have been widely explored electrocatalytic HER due their unique electronic properties, performance, and superior anti-corrosion feature. However, the activities nickel phosphide electrocatalysts are still low practical...
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...
Electrochemical water splitting driven by the electricity generated from renewable energy is an ideal sustainable approach for hydrogen production, where efficient evolution reaction (HER) electrocatalyst indispensable. Ni‐based electrocatalysts are widely investigated HER in different electrolytes due to their advantages of high Earth abundance, remarkable corrosion resistance, electrocatalytic performance, and electrical conductivity. Although several exhibit catalytic performance...
Nickel phosphides have been widely explored for electrocatalytic hydrogen evolution reaction (HER) due to their high activity and durability. To date, however, it is still a big challenge develop facile scalable approaches preparing nickel phosphide structures with HER performance practical applications. Here, general strategy demonstrated preparation of porous nanosheets on arbitrary substrates by electroless Ni plating the substrate followed convenient stable phosphidation reaction....
Chemical demulsification is the most frequently used method. Various experimental approaches have been developed to investigate process and mechanism. This paper designed three different hydrophobic monomer composition of comb‐like block polyether demulsifiers, mechanism demulsifier in crude oil emulsions were studied by dissipative particle dynamics simulation. The can be described as follows: (1) flocculation stage; (2) coalescence stage. constant has a great effect on efficiency. Radial...
Tetrakis (4-carboxyphenyl) porphyrin (TCPP) and polyelectrolyte poly(N-methyl-2-vinylpyridinium iodide)-b-poly(ethylene oxide) (PMVP41-b-PEO205) can self-aggregate into polyion complex (PIC) micelles in alkaline aqueous solution. UV-vis spectroscopy, fluorescence transmission electron microscope, dynamic light scattering were carried out to study PIC micelles. Density functional theory (DFT) calculation method was applied the interaction of TCPP PMVP41-b-PEO205. We found that H-aggregates...
Polyion complexes have been known about for decades, with their applications mainly restricted to drug and gene delivery. In this study, we show that by the introduction of fluorescent charged molecules into a polyion complex, it can be used as specific detection system surfactants. The fluorescence 8-hydroxy-1,3,6-pyrenetrisulfonic acid trisodium salt (HPTS) is quenched in ionic while recovered addition surfactant sodium dodecylbenzenesulfonate (SDBS), due stronger interaction between SDBS...
The singlet oxygen quantum yields of photosensitizers in different solvents are very important for photodynamic therapy (PDT). Here, we investigated the tetrakis (4-carboxyphenyl) porphyrin (TCPP) various by iodide method. Results indicate that TCPP has formation efficiency solvents. When compared to dissolved water, showed higher methanol and ethanol, but lower DMF under identical conditions. In particular, rapidly precipitated acetone after potassium added solution. salting out effect was...
This study reports a facile strategy to prepare IrOx nanoparticle films on FTO substrates through simple spin-coating, annealing, and plasma treatment, which act as efficient electrocatalysts towards oxygen evolution reaction (OER). Typical amorphous film obtained by annealing at 300 °C air-plasma treatment exhibits excellent OER performance in acidic electrolyte with low overpotential of 290 mV 10 mA cm−2, Tafel slope 55.4 dec−1, an ultrahigh mass activity 993 A g−1 1.55 V, is among the...
