Urchin-like TiO2/CdS Nanoparticles Forming an S-scheme Heterojunction for Photocatalytic Hydrogen Production and CO2 Reduction

“…It can be observed that the TCE exists in the form of an urchin-like cluster from Figures S1e and S2a,b. For the TiO 2 /CdS nanoparticle heterojunction, lattice fringes of TiO 2 and CdS were detected, and a lattice fringe of 0.196 nm, corresponding to the (200) crystallographic plane of TiO 2 , and a lattice fringe of 0.321 nm, corresponding to the (101) crystallographic plane of CdS, can be observed in the HRTEM image (Figure c) . This interface also proves that CdS and TiO 2 form a heterojunction in TCE.…”

Meanwhile, elemental mapping (EDS) of the TCE showed that the elements of Ti, O, S, and Cd were uniformly distributed in the tested area, verifying the architecture of the TiO 2 /CdS heterostructure (Figure 2e−i), which was also in agreement with the results of the previous XRD analyses, and the elemental contents of the tested elements in Figure 2d were the same as those of the reactants, which proved that the catalysts used in the experiment were well synthesized.…”

Novel double-layer core–shell photocatalyst CdS–TiO2@NH2-MIL-101: enhanced conversion of CO2 and CH4 at ambient temperature

“…Additionally, the Cd 3d spectrum displayed two different spectral peaks located at 405.7 and 412.6 eV (Fig. 4d), which were assigned to the Cd 3d 5/2 and Cd 3d 3/2 orbitals of Cd, 57,58 respectively. Four peaks at 248.8, 286.3, 288.9, and 291.0 eV were visible in the MOF C1 XPS patterns, indicating the existence of C–C, C–N, and CO bonds in the MOF 51,59 (Fig.…”
