Prolonged electron lifetime in sulfur vacancy-rich ZnCdS nanocages by interstitial phosphorus doping for photocatalytic water reduction

Abstract

Hollow metal sulfides have been extensively investigated as photocatalysts for hydrogen evolution reaction (HER) due to their enhanced light harvesting ability and sufficient catalytic sites. However, their HER performances are...

A visible-IR responsive BiVO4/TiO2 photoanode with multi-effect point defects for photothermal enhancement of photoelectrochemical water splitting

“…This ensures O V s in both BVO and TNA as electron traps and not as recombination centers. 29 Lastly, the synergistic effect of two dopants achieves the smallest bandgap of co-doped BVO via the shift of the VBM and CBM in the opposite direction, but the E fb remains almost unchanged (Fig. S14d, ESI †).…”

A Synergistic Combination of P‐doped Zn0.5Cd0.5S and CoP for Dual‐Stage Electron Trapping and Its Application in Seawater Splitting

“…This can be attributed to the substantial amount of S vacancies that were inherently induced upon introduction of foreign atoms, which in this circumstance are the P atoms. [ 27 ] The electrons are highly susceptible to be attracted toward the S vacancy defects, in which the electron density around Zn is significantly lowered instead, therefore causing a positive shift toward higher binding energy in the Zn 2 p peaks. The same upshifting phenomenon also occurred for the high‐resolution Cd 3 d spectra, as delineated in Figure 1c.…”

Metal Cation Valency Dependence in Morphology Evolution of Cu2−xS Nanodisk Seeds and Their Pseudomorphic Cation Exchanges

“…The properties of colloidal inorganic nanoparticles (NPs) including catalytic, electronic, optical, and magnetic performances are greatly affected by their morphologies, suggesting opportunities for enabling applications, which are not possible by poorly defined or bulk materials [1–5] . In recent years, the morphology and according properties of Zn– and Cd–chalcogenide compositions have been exploited and rationalized [6–15] . Nevertheless, their further development into particular applications are somewhat limited by the concerns of fabrication technique for complex (hetero)structures.…”

“…[1][2][3][4][5] In recent years, the morphologya nd according properties of Zn-and Cd-chalcogenide compositions have been exploited and rationalized. [6][7][8][9][10][11][12][13][14][15] Nevertheless, their furtherd evelopment into particular applications are somewhat limited by the concerns of fabrication technique for complex (hetero)structures. To circumvent this obstacle, an attractive alternative strategy is cation exchange (CE).…”
