Preparation and electrochemical capacitance of MnO2 thin films doped by CuBi2O4

Rational design of hierarchically-structured CuBi2O4 composites by deliberate manipulation of the nucleation and growth kinetics of CuBi2O4 for environmental applications

“…[3][4][5] Bismuth-based nanomaterials have a relatively high density of surface hydroxyl groups which can act as a platform for synergistic coupling with other metal oxides for performance enhancement. 6 To date, there are various reports on the promising use of CuBi 2 O 4 composites for various applications including photoelectrochemical application, [7][8][9] water splitting, [10][11][12][13] electrochemical capacitors, 14 sulfate radical generation 15 and photocatalysis. [16][17][18][19][20][21][22][23][24][25] These studies also demonstrated that CuBi 2 O 4 exhibited poor performance on its own but could have an attractive synergistic effect and heterojunction when coupled with other metal oxides.…”

MnO2‐Based Materials for Environmental Applications

“…Many heterojunctions formed by AB 2 O 4 spinel and MnO 2 have also been reported in recent years, including ZnCo 2 O 4 /MnO 2 , [ 232–236 ] ZnFe 2 O 4 /MnO 2 , [ 237 ] CoFe 2 O 4 /MnO 2 , [ 238 ] MnFe 2 O 4 /MnO 2 , [ 239 ] MnCo 2 O 4 /MnO 2 , [ 240 ] NiCo 2 O 4 /MnO 2 , [ 241,242 ] and CuBi 2 O 4 /MnO 2 . [ 243,244 ] Zhang et al. [ 241 ] constructed a MnO 2 @NiCo 2 O 4 3D nanowire array, using nickel foam as a carrier, hollow NiCo 2 O 4 spinel as a core, and MnO 2 NPs as a shell (Figure 16c).…”

Hierarchical CuBi2O4 microspheres as lithium-ion battery anodes with superior high-temperature electrochemical performance

“…Nevertheless, to the best of our knowledge, direct application of CuBi 2 O 4 as an anode material for LIBs has not been reported yet. [25][26][27][28][29][30][31] We pay attention to this binary bismuth-based transition-metal oxide due to its multiple oxidation states. In fact, CuBi 2 O 4 could be considered as a solid solution composite, which consists of CuO and Bi 2 O 3 .…”
