A review on 2D MoS2 cocatalysts in photocatalytic H2 production

The improved photocatalytic activity of highly expanded MoS2 under visible light emitting diodes

“…MoS 2 nanostructure is a transition metal dichalcogenide (TMDs) material that is commonly uses as a co-catalyst in photocatalytic activity [16,17]. Nevertheless, MoS 2 is a potential candidate in photocatalysis due to its unique physiochemical and optical properties that can be modified by reducing the MoS 2 staking layer [18].…”

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.…”

Hierarchical Ternary Sulfides as Effective Photocatalyst for Hydrogen Generation Through Water Splitting: A Review on the Performance of ZnIn2S4

“…The mechanism of photo splitting of water involves absorption of radiation with an energy greater than the bandgap of the photocatalyst. It mainly consists of two half-reactions: oxidation of water to form O2 and the reduction of protons to form H2 [7][8][9][10][11][12][13][14][15] H2O + h + vb → 2H + + ½ O2 [Photooxidation of water] (1) 2 H + + 2 e − cb → H2 [Photoreduction of protons]…”
