Synergistic Interaction of MoS2 Nanoflakes on La2Zr2O7 Nanofibers for Improving Photoelectrochemical Nitrogen Reduction

“…The peaks present at 181.9 and 184.3 eV correspond to Zr 3d 5/2 and Zr 3d 3/2 of the Zr 4+ ions, respectively. The La 3d spectrum displays satellite peaks for the corresponding ions, which is a universal phenomenon of transition metal oxides and rare earth metals . The O 1s spectra in Figure d display a reduced curve area for the oxygen vacancy signal present at approximately 531.4 eV for the MoS 2 @LZO electrocatalyst compared to pristine LZO.…”

“…LZO nanofibers reduce the band gap energy of the pristine MoS 2 nanostructures, which provides a very small energy barrier for the generation of electron–hole pairs. This increases the photoelectron population on the conduction band and enhances the surface with increased active sites for efficient catalytic activity. ,, …”

“…Pan and co-workers observed that the defect-to-ordered phase structure in La 2 Zr 2 O 7 occurs at 875 °C when the material contains both fluorite and pyrochlore structures. The heterostructure formation is found to produce an increased surface area and varied grain boundaries that make it a budding choice for electrocatalytic applications. ,, …”

Application of PANI/TiO2 Composite for Photocatalytic Degradation of Contaminants from Aqueous Solution

“…When the optimized PANI/TiO 2 composite was applied to the photocatalytic degradation of 5 mg/L BPA, BPA was degraded by 80 ± 0.75% in 360 min (Figure 8a). To calculate the degradation rate (k app ), the pseudo-first-order degradation kinetics of BPA by PANI/TiO 2 were plotted (Figure 8b) to solve Equation (1): [27] ln(C 0 /C) = k app t…”

Highly efficient synthesis of extremely fine nano-SnO2 photocatalytic materials by dealloying Cu50Sn50 alloy powders with mainly exposed {123} facts in η-Cu6Sn5

“…Semiconductor photocatalytic technology is extensively regarded as the most effective and green approach for solving the environment problems caused by toxic organic pollutants in industrial wastewater. 1,2–4 Hence, numerous studies have been carried out to obtain semiconductors with enhanced photocatalytic activities through developing synthesis methods, such as hydrothermal/solvothermal, 5–10 precipitation, 11,12 sol–gel, 13,14 electrospinning, 15,16 and template assisted. 17,18 Among these, dealloying could be a very promising method 19–21 because it avoids sophisticated laboratory equipments, strict reaction conditions, complex preparation procedures, and large numbers of chemical reactions, which are usually disadvantageous factors in other methods.…”
