“…It has been reported earlier that the Bragg peaks of the Bi 2 O 3 obtained using PMMA template synthesis were broad owing to the ultrafine grain size of the material. 14 In a recent report, Deng et al reported the nearly amorphous nature of the Bi 2 O 3 /rGO nanocomposite. 17 Undoubtedly, in the present instance, the presence of sharp Bragg peaks for Bi 2 O 3 clearly indicates its highly crystalline nature.…”

The present investigation elucidates a simple hydrothermal method for preparing nanostructured bismuth oxide (Bi 2 O 3 ) and carbon quantum dot (CQD) composite using spoiled (denatured) milk-derived CQDs. The formation of the CQD–Bi 2 O 3 composite was confirmed by UV–vis absorption, steady-state emission, and time-resolved fluorescence spectroscopy studies. The crystal structure and chemical composition of the composite were examined by X-ray diffraction, Fourier transform infrared spectroscopy, Raman spectroscopy, and thermogravimetric analysis. The surface morphology and the particle size distribution of the CQD–Bi 2 O 3 were examined using field emission scanning electron microscope and high-resolution transmission electron microscope observations. As an anode material in lithium-ion battery, the CQD–Bi 2 O 3 composite exhibited good electrochemical activity and delivered a discharge capacity as high as 1500 mA h g –1 at 0.2C rate. The supercapacitor properties of the CQD–Bi 2 O 3 composite electrode revealed good reversibility and a high specific capacity of 343 C g –1 at 0.5 A g –1 in 3 M KOH. The asymmetric device constructed using the CQD–Bi 2 O 3 and reduced graphene oxide delivered a maximum energy density of 88 Wh kg –1 at a power density of 2799 W kg –1 , while the power density reached a highest value of 8400 W kg –1 at the energy density of 32 Wh kg –1 . The practical viability of the fabricated device is demonstrated by glowing light-emitting diodes. It is inferred that the presence of conductive carbon network has significantly increased the conductivity of the oxide matrix, thereby reducing the interfacial resistance that resulted in excellent electrochemical performances.

“…24) At around 1.4 V and a gently potential drop at 1.30.9 V, a reaction for reducing of Bi 2 O 3 to Bi is progressing. Li et al reported that the reaction formula (3.2, 3.3 in which the monoclinic ¡-Bi 2 O 3 or tetragonal ¢-Bi 2 O 3 is reduced to Bi proceeds 1.2 or 1.4 V. 25) However, from the crystallization behavior of this glass system, cubic Bi 2 O 3 crystal was precipitated. Since there is no report on the lithium ion deintercalation behavior of cubic Bi 2 O 3 crystal, this plateau may be unique to this glass.…”

“…(3.2). 12), 25) On the other hand, the initial charge capacity of the bismuth micro sphere dispersed glass-ceramics was 350 mAh/g. Since the capacities in the second cycle showed similar values of 230 mAh/g, the irreversible electrochemical reaction was successfully reduced by the formation of bismuth metal particles.…”

The crystallization behavior of bismuth borate glass in hydrogen argon mixed atmosphere was examined. When the 70B 2 O 3 30Bi 2 O 3 glass prepared by the melt quenching method was heat treated in a 5% hydrogen-95% argon atmosphere, spherical bismuth metal particles were formed in the glass matrix at 380°C, which is higher than glass transition temperature at 336°C and close to crystallization temperature at 399°C. As increase of heat treatment temperature, the diameter of bismuth grain was increased. Electrochemical activity of bismuth metal containing glass-ceramics was also evaluated as a negative electrode in lithium ion battery. Suppression of irreversible capacity at initial cycle due to lithium insertion was successfully performed by reductive heat treatment for crystallization of bismuth metal into glass matrix.

“…The as-prepared p-Bi 2 O 3 /Ni delivered a lithium storage capacity of 668 mAh g −1 at 800 mA g −1 , much higher than that of Bi 2 O 3 powder prepared by polymer-assisted solution (p-Bi 2 O 3 ) and commercial Bi 2 O 3 (c-Bi 2 O 3 ). Besides, Li et al [108] prepared 3D ordered macroporous (3DOM) β-Bi 2 O 3 anode materials for LIBs via a modified colloidal crystal templating method, which exhibited average discharge capacity of 529 mAh g −1 at 0.2 C rate. Although some progress has been made, more efforts are required to further improve the cycle performance of Bi 2 O 3 .…”
