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.

BiOx species have been identified as the most important active for electroreduction of CO2 to HCOOH over Bi-based materials. However, are unstable under high reduction current/potential, limiting further industrial application. Herein, we constructed robust by incorporating sodion (Na+) into Bi nanosheets (denoted Na-Bi nanosheets). The negatively charged anchored stable Na+ in displayed highly structural stability during electroreduction. When applied current density (j) was set from -200 -1200 mA cm-2, all faradaic efficiency (FE) HCOO- (FEHCOO-) maintained 90% flow-cell device, whereas FEHCOO- pure dramatically decreased 5%. Mechanistic study revealed that Na+-anchored can not only alter potential-limiting step (PLS) but also decrease energy barrier PLS HCOOH.
