Insights on the role of β-Bi2O3/Bi5O7NO3 heterostructures synthesized by a scalable solid-state method for the sunlight-driven photocatalytic degradation of dyes

A Short Review on Biomedical Applications of Nanostructured Bismuth Oxide and Related Nanomaterials

“…Furthermore, several attempts were reported in the literature [28][29][30][31][32] pursuing the thermal oxodehydration of Bi(NO3)3•5H2O with the formation of a series of complex species as summarized in Figure 1. An interesting study was reported by Tanveer et al [17] about the transition from Bi(NO3)3•5H2O to Bi5O7NO3 showing how it is possible to isolate a species of Bi5O7NO3 tailored on the surface with β-Bi2O3.…”

“…Organo-bismuth derivatives are not the only species of great interest as nanosized oxides and related materials have raised more and more interest in the scientific community due to their cost-effective fabrication processes [14,15], high stability [16] and versatility in terms of morphology [17,18]. Furthermore, the high atomic number of bismuth brings about a high energy radiation attenuation larger than that of lead at an almost negligible risk of toxicity [19].…”

Preparation of BiOCl0.9I0.1/β-Bi2O3 composite for degradation of tetracycline hydrochloride under simulated sunlight

“…Conversely, β-Bi2O3 is also a common germanium-containing semiconductor. Similarly, BiOX (X = Cl, Br and I) exhibits good absorption of visible light; thus, it can significantly facilitate the production of superoxide and hydroxide species under exposure to sunlight [31]. Therefore, in this work, it is chosen for combination with BiOCl0.9I0.1, which has an indirect bandgap, to form a composite catalyst [32].…”

Bimetallic Metal‐Organic Framework Derived ZnO/Ni0.9Zn0.1O Nanocomposites for Improved Photocatalytic Degradation of Organic Dyes

“…At present, numerous metal oxides such as ZnO, CdS, TiO 2 , Bi 2 O 3 , and Fe 2 O 3 , have been investigated for their photocatalytic activities. Besides them, nickle oxide (NiO) is also a promising photocatalyst because of its characteristics of low cost, innocuity, high hole mobility, and high photosensitivity .…”
