Built-in electric field-assisted charge separation over carbon dots-modified Bi2WO6 nanoplates for photodegradation

Effect of Few-Layer Ti3C2Tx Supported Nano-Ni via Self-Assembly Reduction on Hydrogen Storage Performance of MgH2

“…Figure S5 shows the electrostatic potentials along the c axis of Ni(111) and FL-Ti 3 C 2 T x (001) slabs. According to Fermi levels and vacuum energy levels, the calculation results show that the Φ value of Ni(111) (5.03 eV) is lower than that of FL-Ti 3 C 2 T x (001) slabs (5.86 eV), indicating that some electrons transfer from Ni to FL-Ti 3 C 2 T x upon the combination . The electronic coupling between Ni and FL-Ti 3 C 2 T x was further investigated via charge density calculations.…”

Figure 9a E slab-H means the energy of the surface slab after hydrogen adsorption, E slab is the energy of the surface slab, and E H is the energy of single hydrogen atoms.…”

Rational Design of an Efficient S-Scheme Heterojunction of CdS/Bi2WO6–S Nanocomposites for Photocatalytic CO2 Reduction

“…The 4e). 35,36 Ultraviolet−visible diffuse reflectance spectroscopy (UV−vis DRS) of the 0.5 CdS/Bi 2 WO 6 −S nanocomposite exhibits an intensive absorption in the visible light region, and its edge can be extended to 590 nm (Figure 5). It is obvious that the light absorption of CdS/Bi 2 WO 6 −S nanocomposites is a coupling of that of cubic CdS and orthorhombic Bi 2 WO 6 nanosheets because bare cubic CdS and orthorhombic Bi 2 WO 6 nanosheets possess band gaps of 2.4 and 2.8 eV, respectively.…”

“…In comparison to those in bare CdS, both peaks in the Cd 3d and S 2p regions show a higher binding energy shift, while the peaks in Bi 4f and W 4f regions shift toward a lower binding energy compared to those in bare Bi 2 WO 6 –S, suggesting that there exists interactions between CdS and Bi 2 WO 6 –S of the 0.5 CdS/Bi 2 WO 6 –S nanocomposite. The XPS in the O 1s region can be deconvoluted into three peaks at 531.0, 529.0, and 529.8 eV, which are ascribable to surface-adsorbed oxygen and lattice O in Bi–O and W–O of Bi 2 WO 6 , respectively (Figure e). , …”

Filterless narrowband near-infrared Si photodetector

“…The build-in electric eld can facilitate photogenerated electron-hole pairs separation and decrease the recombination. 41 On the other hand, the C-AFM of D18:Y6 lm on Si nanograting is tested to investigate the photocurrent distribution under the bias voltage of -2 V with the light excitation. The AFM and corresponding light C-AFM mapping are shown in Fig.…”
