Vanadium Carbide (V2CTx) MXene-Supported Exfoliated g-C3N4 with the Role of Hole Scavenger as a Rapid Electron Transfer Channel for Enhancing Photocatalytic CO2 Reduction to CO and CH4

“…The charge transfer mechanism over the V 2 C/ECN composite could be discussed based on the work function of V 2 C and ECN samples. The work function of V 2 CT x (ϕ = 4.5 eV) 37 is higher than the work function of ECN (3.14 eV), 15 which could promote the transfer of electrons from the ECN to V 2 C-MXene. Previously, a Fermi level of 6.87 eV was obtained for V 2 C, whereas a Fermi level of 7.86 eV was observed for VO 2 , which confirms the transfer of electrons from V 2 C to VO 2 .…”

Synthesis of AgBr/Ti3C2@TiO2 ternary composite for photocatalytic dehydrogenation of 1,4-dihydropyridine and photocatalytic degradation of tetracycline hydrochloride

“…Two peaks appear at the binding energies of 281.6 eV and 288.8 eV, corresponding to the Ti-C bond and the C-F bond, respectively. 43,45 In addition, the O 1s XPs spectrum showed two distinct peaks at 532.2 eV and 530.3 eV (Fig. 5D), the highest peak at 530.3 eV usually represent the lattice oxygen in TiO 2 , which also indicated that TiO 2 was successfully grown in situ on Ti 3 C 2 .…”
