Ecofriendly hydrogen production from abundant hydrogen sulfide using solar light-driven hierarchical nanostructured ZnIn2S4 photocatalyst

Facile Synthesis of Novel Redox-Mediator-free Direct Z-Scheme CaIn2S4 Marigold-Flower-like/TiO2 Photocatalysts with Superior Photocatalytic Efficiency

“…Similar microspheres with uniform marigold flower-like morphologies have been reported for CdIn 2 S 4 and ZnIn 2 S 4 . 24,45 From these results, we conclude that CIS NPs were initially formed and aggregated into the CIS spheres; these grew into petals or sheets that then self-assembled to form the uniform hierarchical marigold flower-like morphology of the CIS microspheres. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 Scheme 1.…”

Preparation of ZnIn2S4/K2La2Ti3O10 composites and their photocatalytic H2 evolution from aqueous Na2S/Na2SO3 under visible light irradiation

“…The studies by Shen et al [7] and Chaudhari et al [8] have revealed that ZnIn 2 S 4 was active for photocatalytic H 2 generation under visible light irradiations. However, the smaller band gap of ZnIn 2 S 4 (2.06-2.58 eV) [9,10] can reduce the photoactivity by increasing the recombination rate between electrons and holes [11].…”

Graphene-wrapped Ag 3 PO 4 /LaCO 3 OH heterostructures for water purification under visible light

“…One of the key objectives in this field is to develop high efficiency photocatalyst materials that can efficiently utilize sunlight as the energy source [5]. Thus far, various visible light active photocatalysts have been developed, such as NiS/CdS [6], ZnInS 4 [7], AgO/Ag 2 Mo 2 O 7 [8] , CdInS 4 [9], and TiO 2-x N x [10]. However, the efficiency of these photocatalysts is still too low for industrial application, and therefore materials with high efficiency and long-term stability are still being actively sought [11].…”
