Direct Z-Scheme In2O3/In2S3 Heterojunction for Oxygen-Mediated Photocatalytic Hydrogen Production

“…As shown in Figure a, In 2 O 3 exhibits a broad PL emission band with several peaks located in the range of 370–430 nm, while In 2 S 3 shows an emission band centered at 535 nm. For the IS-HOS samples, the PL intensities were greatly quenched, indicating improved charge recombination abatement in the heterostructures compared to the single-component In 2 O 3 and In 2 S 3 photocatalysts . Overall, the extent of PL quenching followed the order of 500IS-HOS > 600IS-HOS > 700IS-HOS > 400IS-HOS, which correlates well with the photocatalytic activities of the samples.…”

“…For the IS-HOS samples, the PL intensities were greatly quenched, indicating improved charge recombination abatement in the heterostructures compared to the single-component In 2 O 3 and In 2 S 3 photocatalysts. 41 Overall, the extent of PL quenching followed the order of 500IS-HOS > 600IS-HOS > 700IS-HOS > 400IS-HOS, which correlates well with the photocatalytic activities of the samples. The trends of PL quenching and photoactivity signify that the photocatalytic performance of the IS-HOS samples relies on their superior charge separation ability, 11 which was further corroborated by the TRPL results shown in Figure 5b.…”

Recent Progress of Metal Sulfide Photocatalysts for Solar Energy Conversion

“…[ 34–36 ] For instance, a cadmium sulfide/zinc sulfide/zinc oxide (CdS/ZnS/ZnO) composite was studied via partial sulfidation of ZnO followed by deposition of CdS quantum dots. [ 37 ] The synthesized composite displayed a reduced bandgap, extended photon absorption, accelerated charge transfer, and enhanced performance. Tailorable band structures and broadened light absorption of metal sulfides favor efficient charge separation and adequate solar light conversion efficiency in photocatalysis.…”

Cobalt phthalocyanine sensitized MOF on MOF: UiO-66@MIL-88B(Fe)/CoTAPc, photocatalytic activity in the degradation of acid black 210

“…37,38 It's also reported that the multiple interfaces formed in ternary photocatalysts can construct multiple pathways for the transfer of photogenerated charge carriers, and thus effectively promote the photocatalytic activity. 39,40 Inspired by the above mentioned points, herein, we reported a ternary photocatalyst constructed by growing cobalt(II) 4,9,16,23-tetraaminophthalo-cyanine 2-hydrate (CoTAPc) on petal-shaped UiO-66@MIL-88B(Fe), which was pre-constructed by in situ growing MIL-88B(Fe) on the outer surface of UiO-66. 41,42 Interestingly, the cross-packed UiO-66@MIL-88B(Fe) allowing a uniform dispersion of CoTAPc via chemical bonding provides an increased surface adsorption owing to the large specific surface area, an enhanced visible light harvesting ability due to the uniformly dispersed CoTAPc, an efficient charge transfer lying in the close cross-packed UiO-66@MIL-88B(Fe), and also a better structure stability thanks to the excellent stability of UiO-66.…”
