Synthesis of Nanosheets from Layered Bismuth Oxide Bi_2.2Sr_1.8CaFe₂O₉ without Using Organic Exfoliation Agents

Inorganic Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Янв. 7, 2025

Bismuth oxide nanosheets were synthesized through the exfoliation of layered compounds without any organic agents. The compound Bi2.2Sr1.8CaFe2O9, comprising Bi–O layers and Sr–Ca–Fe–O layers, was as starting material. selectively dissolved by shaking in 0.3 M HNO3 solution, yielding aggregates consisting solely bismuth layers. Subsequent ultrasonic treatment these pure water led to formation nanosheets. nanosheet exhibited a higher photocatalytic activity for H2 production compared α-Bi2O3. Characterization using FE-SEM, AFM, HAADF-STEM revealed that exhibit complex structure. They consist crystalline framework ε-bismuth oxide, interspersed with island-like regions amorphous or oxide. Additionally, self-standing membranes nanosheets, aligned [001] direction, successfully synthesized. This method, which involves partial dissolution structure acid followed processing water, is anticipated be applicable other well.

Selective HCOOH Production over Wide Potential Range via Defective Oxide‐Derived Bismuth

Advanced Sustainable Systems, Год журнала: 2023, Номер 8(2)

Опубликована: Сен. 24, 2023

Abstract Electrochemical reduction of CO 2 toward value‐added liquid fuel is a promising route to achieve the carbon neutrality. Especially for electroreduction formic acid production, despite favorable activity and selectivity can be achieved, unstable Faradaic efficiency (FE) in wide potential range poor energy remain bottlenecks. Herein, this study reports metallic Bi catalyst (B‐ArH ‐2) derived from defective O 3 , which achieves nearly 100% FE HCOOH production over broad (−0.7 −1.1 V) with an outstanding cathodic 71%. Additionally, B‐ArH ‐2 displays high partial current density ( j 27.5 mA cm −2 ) rate (475 µmol h −1 long‐term stability (20 h).
