“…The surface potential of NiCo-OH (47.48 mV) is higher than that of NiCoS (27.94 mV) (as shown in Figure 3e and 3f), which indicates that the Fermi energy level of NiCo-OH is higher than that of NiCoS. 44 Based on the measured UV−vis absorption spectra of NiCo-OH and NiCoS (Figure S15a,b), (αhν) 2 was plotted versus the photon energy (hν) using the Kubelka−Munk method (both NiCo-OH and NiCoS are direct bandgap semiconductors). 45 By extrapolating the plots to (αhν) 2 = 0, the bandgap (E g ) values of NiCo-OH and NiCoS are estimated to be 2.89 and 2.77 eV (Figure S15c,d), respectively.…”

“…The surface potentials of the samples were investigated by Kelvin probe force microscopy (KPFM). The surface potential of NiCo-OH (47.48 mV) is higher than that of NiCoS (27.94 mV) (as shown in Figure e and f), which indicates that the Fermi energy level of NiCo-OH is higher than that of NiCoS . Based on the measured UV–vis absorption spectra of NiCo-OH and NiCoS (Figure S15a,b), (α h ν) 2 was plotted versus the photon energy ( h ν) using the Kubelka–Munk method (both NiCo-OH and NiCoS are direct bandgap semiconductors) .…”

Herein, a reverse bias heterojunction NiCoS/NiCo-OH with mesopores as the positive electrode was constructed by interface engineering. During the process of charging, the application of a positive bias potential by the external circuit to the reverse bias heterojunction NiCoS/NiCo-OH enhances the accumulation of charges within the NiCoS nanosheets. Under the modulation of the built-in electric field at the interface, the mesoporous interface of NiCo-OH acts as a receiver, collecting charges from NiCoS nanosheets and forming a channel leading to efficient ion diffusion and charge transfer. The specific capacity of the NiCoS/NiCo-OH electrode is up to 406.5 mA h g −1 at 1 A g −1 . It demonstrates ultrahigh rate performance, reaching 81.9% (50 A g −1 ) and 77.4% (100 A g −1 ). The hybrid supercapacitor NiCoS/ NiCo-OH//FNG shows a high energy density of 51.3 W h kg −1 at 1650 W kg −1 . Moreover, the capacity of the Zn||NiCoS/NiCo-OH battery reaches 419.1 mA h g −1 cathode at 1 A g −1 , and it can still maintain 73% (306.3 mA h g −1 cathode ) at 100 A g −1 .

“…By analysing the intercept of the tangent line on the X axis, the flat band potential (Efb) of MIL-100(Fe) was calculated to be −0.60 V (vs. SCE). According to the equation E(vs. NHE) = E(vs. SCE) + 0.051pH + 0.24 [45][46][47], the flat band (Efb) was 0.083 (vs. NHE). The Mott-Schottky curve of MIL-100(Fe) showed a negative tangent slope indicating the presence of an n-type semiconductor.…”

With the rising incidence of various diseases in China and the constant development of the pharmaceutical industry, there is a growing demand for floxacin-type antibiotics. Due to the large-scale production and high cost of waste treatment, the parent drug and its metabolites constantly enter the water environment through domestic sewage, production wastewater, and other pathways. In recent years, the pollution of the aquatic environment by floxacin has become increasingly serious, making the technology to degrade floxacin in the aquatic environment a research hotspot in the field of environmental science. Metal–organic frameworks (MOFs), as a new type of porous material, have attracted much attention in recent years. In this paper, four photocatalytic materials, MIL-53(Fe), NH2-MIL-53(Fe), MIL-100(Fe), and g-C3N4, were synthesised and applied to the study of the removal of ofloxacin and enrofloxacin. Among them, the MIL-100(Fe) material exhibited the best photocatalytic effect. The degradation efficiency of ofloxacin reached 95.1% after 3 h under visible light, while enrofloxacin was basically completely degraded. The effects of different materials on the visible photocatalytic degradation of the floxacin were investigated. Furthermore, the photocatalytic mechanism of enrofloxacin and ofloxacin was revealed by the use of three trappers (®O2−, h+, and ®OH), demonstrating that the role of ®O2− promoted the degradation effect of the materials under photocatalysis.
