Water splitting is an important way to obtain hydrogen applied in clean energy, which mainly consists of two half-reactions: evolution reaction (HER) and oxygen (OER). However, the kinetics OER water splitting, occurs at anode, slow inefficient, especially acid. Currently, main catalysts are still based on noble metals, such as Ir Ru, active components. Hence, exploration new with low cost, high activity, stability has become a key issue research electrolytic production technology. In this...
Using titanium, boron carbide and iron-based alloy powders as reactive sources, an Fe-based cladding coating reinforced by in situ synthesised TiC-TiN particles was fabricated using the plasma method. The effects of Ti B 4 C content on phase composition, microstructure, microhardness, wear resistance corrosion were studied. coatings composed α-Fe, Cr, Fe 3 C, TiC, TiN, 23 6 (C,B) . relative , layer increased with increase contents. hardness, content. results indicated that composite...
This present work investigates the effects of sintering temperature on densification, mechanical properties and microstructure Al-based alloy pressed by high-velocity compaction. The green samples were heated under flow high pure (99.99 wt%) N2. heating rate was 4 °C/min before 315 °C. For reducing residual stress, isothermally held for one h. Then, specimens respectively at 10 to between 540 °C 700 °C, h, then furnace-cooled room temperature. Results indicate that when sintered 640 both...
Abstract Bi 4 TaO 8 Cl and Cl:Gd 3+ photocatalysts were synthesized by the solvothermal technique. The phase, microstructure, optical properties, photocatalytic activities investigated. Both have singly orthorhombic phase flower‐like hierarchical structure. has higher activity of MB than that under visible light irradiation. is induced its lower band gap energy, efficiency charge separation, transfer process, as well photogenerated carriers with a longer time, which are confirmed absorption...
Microarc oxidation (MAO) coatings were formed on AZ91D magnesium alloy in zirconate–phosphate electrolytes with and without the addition of titanium carbide (TiC) niobium (NbC) particles. Surface morphologies, structures, compositions corrosion resistance MAO investigated. The coating based electrolyte was mainly composed MgO, Mg2Zr5O12 some amorphous phases. TiC NbC particles incorporated uniformly distributed coatings. Both increased thickness compactness Electrochemical measurements...
Hydrogen evolution reaction (HER) is one promising technique to obtain high-purity hydrogen, therefore, exploiting inexpensive and high-efficiency HER electrocatalysts a matter of cardinal significance under the background achieving carbon neutrality. In this paper, hydrothermal method was used prepare Cr-NiC2O4/NF (Ni foam) precursor. Then, NiO-Cr-C/NF self-supporting catalyst obtained by heating precursor at 400 °C. The presents 3D cellular nanospheres structure which composed 2D...

Abstract The Microarc Oxidation (MAO) layer on titanium alloy was mainly composed of TiO 2 , and there were some defects, such as holes cracks, which made the performance MAO not ideal. To enhance properties layer, carbide (TiC) particles added to electrolyte a phosphate–silicate system an additive. Consequently, layers containing TiC phase Ti6Al4V produced. process, composition, microstructure, hardness comprehensively analyzed. Their frictional assessed under reciprocating friction...
