Synergy of MXene with Se Infiltrated Porous N‐Doped Carbon Nanofibers as Janus Electrodes for High‐Performance Sodium/Lithium–Selenium Batteries

“…In Figure 2a, the Ti 2p spectrum of PNCNF/Se@MXene consists of four pairs of 2p 3/2 and 2p 1/2 doublets for TiC (455.1/462.0 eV) and TiO (460.3/464.6 eV) as well as the singlet for TiF (456.7 eV) and TiO x (458.8 eV), which correspond to TiC functional groups, and F and O or OH terminal groups on the surface of MXene. [31] Moreover, The Fourier-transform infrared (FTIR) spectrum of PNCNFs, MXene, and PNCNFs/ Se@MXene in Figure S12 (Supporting Information) also revealed that the broadband at 3360-3500 cm −1 and peaks at 1560 cm −1 (the yellow sign) of PNCNFs could be assigned to the stretching vibration of OH groups originated from adsorbed water molecules. The peak at around 1190 cm −1 (the green sign) is assigned as NC stretching vibration of PNCNFs.…”

Dual Strategies of Metal Preintercalation and In Situ Electrochemical Oxidization Operating on MXene for Enhancement of Ion/Electron Transfer and Zinc‐Ion Storage Capacity in Aqueous Zinc‐Ion Batteries

“…[11] Therefore, it is necessary to develop an applicable methodology for the preparation of the feasible vanadium-based cathode materials with stable phase components and high electronic/ionic conductivities to improve the capacity and cycling life of ZIBs. [29,34] Over the past decade, MXenes have grown into key versatile 2D materials that have been widely applied in photodetectors, [35] pollutant degradation, [36] sensors, [37] and energy storage and conversion. [38][39][40] Equipped with nanolaminate microstructure, superior conductivity, and adequate surface chemistry, [41] MXenes provide a great opportunity for fabrication of highperformance ZIBs.…”

Self-Assembly of Bi2Sn2O7/β-Bi2O3 S-Scheme Heterostructures for Efficient Visible-Light-Driven Photocatalytic Degradation of Tetracycline

“…Figure a shows the PL spectra of the Bi 2 Sn 2 O 7 /β-Bi 2 O 3 heterojunction (excitation wavelength [λ ex ]: 530 nm). Semiconductors with higher PL emissions can recombine more photocarriers in general. − BSO/BO-0.4 had a lower quenching PL emission intensity than Bi 2 Sn 2 O 7 and β-Bi 2 O 3 , which indicates that construction of the Bi 2 Sn 2 O 7 /β-Bi 2 O 3 heterojunction hinders the recombination of the photogenerated carriers, ensuring that the photogenerated carriers last longer and that interfacial charge transfer is more efficient. Thus, the photocatalytic performance of the Bi 2 Sn 2 O 7 /β-Bi 2 O 3 heterojunction could be improved (notably, BSO/BO-0.4 had the lowest PL emission intensity).…”
