MoS2 as non-noble-metal co-catalyst for photocatalytic hydrogen evolution over hexagonal ZnIn2S4 under visible light irradiations

Nanohybrid MoS2-PANI-CdS photocatalyst for hydrogen evolution from water

“…HRTEM image (Fig. 3A, inset) shows fringes with lattice spacing of 0.62 nm, which can be assigned to the (0 0 2) plane of hexagonal MoS 2 [4,22]. SAED pattern (Fig.…”

Ternary g-C3N4/ZnO/AgCl nanocomposites: Synergistic collaboration on visible-light-driven activity in photodegradation of an organic pollutant

“…In order to decrease recombination of the charge carriers, one effective strategy is combination of g-C 3 N 4 with semiconductors having proper energy levels [10−12]. Based on this strategy, many g-C 3 N 4 -based composites such as g-C 3 N 4 /ZnO, g-C 3 N 4 /TiO 2 , g-C 3 N 4 /CdS, g-C 3 N 4 /SnO 2 , g-C 3 N 4 /AgCl, g-C 3 N 4 /AgBr, g-C 3 N 4 /AgI, g-C 3 N 4 /BiFeO 3 , g-C 3 N 4 /Ag 3 VO 4 , g-C 3 N 4 /Bi 2 O 2 CO 3 , g-C 3 N 4 /Ag 3 PO 4 , and g-C 3 N 4 /Ni(dmgH) 2 have been prepared and their photocatalytic activities were investigated [14−26]. The results demonstrated that the transfer of electrons from conduction band of g-C 3 N 4 to that of the combined semiconductor helps for separation of the photogenerated electron-hole pairs in g-C 3 N 4 .…”

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]. On the other hand, In belongs to rare metals, the compounds of In are generally very expensive.…”
