Photocatalytic activity of enlarged microrods of α-Bi2O3 produced using ethylenediamine-solvent

MOF-derived Bi2O3@C microrods as negative electrodes for advanced asymmetric supercapacitors

“…71-0465). 24 The EDS spectrum (Fig. 1b) shows the peaks of Bi, O and C. The FT-IR analysis displays that most of absorption peaks of CAU-17 are disappeared (Fig.…”

Carbon Quantum Dots (CQDs) Decorated Bi2O3-x Hybrid Photocatalysts with Promising NIR-Light-Driven Photodegradation Activity for AO7

“…Generally, Bi 2 O 3 exhibits six different crystalline phases denoted as α-, β-, γ-, δ-, ω-, ε-Bi 2 O 3 [12][13][14][15][16][17][18]. Among them, α-Bi 2 O 3 photocatalyst has been frequently studied because of its good structure stability and deep valence band [19][20][21][22][23][24]. However, the photocatalytic activity of bare Bi 2 O 3 is unsatisfactory for practical application due to the high recombination rate of photogenerated electrons and holes.…”

Biotemplate preparation of Bi 2 O 3 nanosheet for enhanced photodegradation of methylene blue

“…As we know, the morphology, size, and specific surface area are crucial to photocatalytic activity [12][13][14]. Up to now, many methods such as microwave irradiation [15], biomimetic method [16], chemical precipitation [17], solvent thermal method [18], femtosecond pulsed laser ablation in liquids [19,20], and surfactant-assistant method [21,22] have been employed to prepare α-Bi 2 O 3 with various morphologies, for instance, laminated structure [23], sphere [24], microrod [21] oblique prism-like structure [25], and flower-shaped superstructure [12]. Although remarkable achievements have been made in these methods, however, there are also several shortcomings such as special facilities requirement [20], high-energy consumption, complicated process [18], polluting [22] etc.…”
