α-NiS–β-NiS growth on Cd_0.5Zn_0.5S formed Schottky heterojunctions for enhanced photocatalytic hydrogen production

Abstract

Novel α-NiS-β-NiS nanosheets modified Cd0.5Zn0.5S nanoparticle heterojunctions have been successfully synthesized via a two-step solvothermal method. The α-NiS-β-NiS/Cd0.5Zn0.5S heterojunctions were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission...

Noble metal-free bimetallic phosphide-decorated Zn0.5Cd0.5S with efficient photocatalytic H2 evolution

“…As illustrated in Fig. 3a, the binding energies of 1022.15 and 1045.1 eV corresponded to Zn 2p 1/2 and Zn 2p 3/2 , 39,42–44 respectively. As shown in Fig.…”

“…2b. It is seen that the characteristic lattice fringes with inter-lattice distance were 0.22 and 0.32 nm, corresponding to (111) and (002) of NiCoP and Zn 0.5 Cd 0.5 S 39–41 (right: Fig. 2b), respectively.…”

Ultra-efficient Nitrogen-Doped Carbon Dots-Supported Nickel Sulfide as a Platinum-Free Electrocatalyst for Overall Water Splitting in Basic Medium

“…The two peaks at 855.10 and 873.15 eV in the XPS spectrum corresponded to Ni 2p 3/2 and Ni 2p 1/2 , respectively, which indicated the existence of Ni 2+ . Additionally, the binding energies of 859.90 and 879.50 eV corresponded to satellite peaks. , …”

“…Additionally, the binding energies of 859.90 and 879.50 eV corresponded to satellite peaks. 45,46 The deconvoluted S 2p spectrum (Figure 6b) showed two peaks at 161.2 and 162.4 eV, which were assigned to S 2p 3/2 and S 2p 1/2 , respectively. A broad satellite peak was also observed at 168.3 eV, which was attributed to the S−O bond.…”

“…A broad satellite peak was also observed at 168.3 eV, which was attributed to the S−O bond. 45,46 Figure 6c shows the deconvolution spectra of C 1s. The three major peaks centered at 288, 285.7, and 284.4 eV correspond to C�O, C−N/C−S, and C�C, respectively.…”
