Hierarchically CdS–Ag2S nanocomposites for efficient photocatalytic H2 production

Unraveling Photoexcited Charge Transfer Pathway and Process of CdS/Graphene Nanoribbon Composites toward Visible‐Light Photocatalytic Hydrogen Evolution

“…Particularly, newly emerged semiconducting materials with tunable bandgap and wide wavelength response were explored. Examples are: In 2 S 3 , SnS 2 , CdS, BiOX (X = Cl, Br, I), ZnIn 2 S 4 , g‐C 3 N 4 , etc. Among these promising photocatalysts, CdS has attracted considerable interest with merits such as a direct‐bandgap (2.4 eV) for visible‐light absorption and a negative potential of the conduction band edge for proton reduction.…”

Nanostructured CdS for efficient photocatalytic H2 evolution: A review

“…cocatalysts to promote the kinetics of photocatalytic H 2 generation. To date, various cocatalysts, such as Au [344,345], Pt [321,346,347], Ag 2 S [348], MXenes [238,[349][350][351][352], CoMoS x [353], MoO x S y [354], MoS 2 [222,[355][356][357][358], Ni 3 C [176], Ni 2 P [359,360], NiS x [63,322,361], NiCoP [362], CoP x [199,363], CuS x [212,246], and WS 2 [364,365] [229] found that a 0.2 molar ratio of NiS improved the average charge carrier lifetime of CdS by 97 times, potentially leading to more efficient charge separation and transfer. They synthesized CdS NWs and NiS with tight connections using a two-pot solvothermal synthesis.…”

Skeletal Cu7S4 Nanocages Wrapped by Few‐Layered Black Phosphorus Nanosheets as an Efficient H2 Production Photocatalyst

“…However, solar‐light‐driven photocatalysts still suffer from fundamental bottlenecks, such as photocorrosion, low chemical stability, noble metal incorporation, inefficient light harvesting, and low photon separation capability, which have limited their importance in commercialized applications [8] . To date, several types of photocatalytic materials have been developed, including transition‐metal oxides (titanate (TiO 2 ), ZnO, and BiVO 4 ), transition‐metal sulfides (TMS) (MoS 2 , WS 2 , and CdS), and graphitic carbon nitride (g−C 3 N 4 ) for clean and sustainable energy production by water splitting [9–20] . Some of these materials such as TiO 2 and ZnO have wide band gaps, resulting in only a 5 % UV light harvesting capability, whereas CdS is limited by their fast electron‐hole recombination, photocorrosion, toxicity, and low stability [21–29] .…”

[9][10][11][12][13][14][15][16][17][18][19][20] Some of these materials such as TiO 2 and ZnO have wide band gaps, resulting in only a 5 % UV light harvesting capability, whereas CdS is limited by their fast electron-hole recombination, photocorrosion, toxicity, and low stability. [21][22][23][24][25][26][27][28][29] On the other hands, gÀ C 3 N 4 has been considered as good visible active material with lower band gap and actively investigated, but its lethargic exciton separation, inadequate light absorption and low practical surface area by staking nature are main obstacles to show the better performance for photocatalytic hydrogen production.…”
