A novel boron-doped porous carbon (BC) was prepared through a facile one step pyrolysis process by using citric acid monohydrate, boron acid, and sodium chloride hybrid as precursor. Based on the analysis of X-ray photoemission spectroscopy and Raman spectroscopy, three boron-doping species (BC3, BC2O, and BCO2) were doped in the carbon lattice. The BC2O and BCO2 can generate abundant extrinsic defects...
Four kinds of solvents, methylene chloride (CH2Cl2), toluene (TOL), ethyl acetate (EtoAc), and dimethyl carbonate (DMC), were added into the 1-butyl-3-methylimidazolium chloroaluminate ionic liquid ([BMIM]Cl/AlCl3 IL) to improve the property of the IL-based electrolyte for aluminum (Al) electrolysis. Solvation effects of these solvents on the physical properties, electrochemical properties, and electroactive...
Red phosphorus (RP) is considered to be one of the promising anode materials for lithium-ion batteries (LIBs) on account of its high theoretical capacity (2596 mAh g−1), abundant resources, and environmental friendliness. However, the intrinsic insulating nature and large volume change during lithium insertion/extraction process lead to drastic capacity loss upon cycling. Recently, great attention...
A template-free electrochemical deposition method for preparation of spherical-like Al particles in the aluminum chloride and 1-butyl-3-methylimidazolium chloride (AlCl3–[Bmim]Cl) system was reported in this work. Effects of current density, electrodeposition time, and temperature on surface morphologies of Al deposits were studied. Results showed that Al particles displayed uniform spherical-like...
N-doped graphene/Bi nanocomposite was prepared via a two-step method, combining the gas/liquid interface reaction with the rapid heat treatment method. The as-prepared sample was characterized by X-ray diffraction (XRD), field-emission scanning electron microscope (FESEM), X-ray photoelectron spectroscopy (XPS), and elemental analyzer. The XRD, FESEM, XPS, and elemental analysis results confirm the...
Spinel structured Li4Ti5O12 was synthesized by a solid-state method using TiO2 and Li2CO3 as starting materials. High-energy ball milling was used to obtain the Li2CO3 samples with different particle size. Then, the effects of Li2CO3 particle size on the structure, morphology, and electrochemical performance of Li4Ti5O12 samples were investigated in detail. The samples were characterized by TG/DTA...
Nickel hydroxide mesoporous structures are synthesized by a simple method in the presence of different additives (oxalic acid, aminoacetic acid, and sulfosalicylic acid). Structural characterizations reveal that the additives can affect the crystal structure, increase the specific surface area, and reduce the pore size of the products. The electrochemical properties of the synthesized Ni(OH)2 samples...
