Bimetallic zeolite-imidazole framework-based heterostructure with enhanced photocatalytic hydrogen production activity

Abstract

The g-C3N4-MoS2 could facilitate the separation as well as utilization efficiency of the photo-generated charge carriers in the ZnM-ZIFs, and hence improved the photocatalytic H2 production with and without sacrificial agent.

Examination of the role and challenges of natural catalysts in hydrogen and biohydrogen production

“…In addition to their mechanism of action, the performance and stability of similar catalysts, particularly zeolite‐based catalysts in SMR, methane decomposition, FA decomposition, DME‐SR, and hydrogen peroxide decomposition, need further investigation. Photocatalytic aqueous biohydrogen generation employs various zeolite catalysts, including ZnS nanosheets generated from the zeolite imidazole framework (ZIF) [89], zeolite/polyaniline@Ni2O3 nanocomposite [76], bimetallic zeolite imidazole [90], and Bi2S3/Y‐Zeolite [77]. Copper metal can also be doped into ZnS to enhance the capabilities of ZnS/zeolite [88].…”

“…Under visible light irradiation, ZnS/ZIF‐8 can produce up to 741.80 𝜇mol g −1 h −1 of biohydrogen. Despite having a significantly smaller surface area than g‐C3N4–MoS2–ZnNi–ZIF catalysts, ZnS/ZIF catalysts can produce nine times more hydrogen [89, 90]. When compared to Bi2S3/Y‐Zeolite catalysts, which have a moderate surface area, ZnS/ZIF‐8 catalysts generate 2.5 times more biohydrogen [77, 89].…”

Recent advancement in bimetallic metal organic frameworks (M′MOFs): synthetic challenges and applications

“…Very recently, Arif et al 201 produce bimetallic zeolite-imidazole frameworks by mixing the Zn(NO 3 ) 2 ·6H 2 O, Ni(NO 3 ) 2 ·6H 2 O and Imidazole solution (Imidazole = C 4 H 6 N 2 ) at room temperature. The prepared M′MOF show controllable flat band position, bandgap, and hydrogen evolution reaction.…”

Construction of donor-mediator-receptor heterojunctions: Ni12P5/In(OH)3/CdIn2S4 ternary catalyst for photocatalytic hydrogen production

“…[10][11][12][13][14][15][16] The development of photocatalytic materials that are low-cost, highly efficient, and stable is still a research focus, despite extensive reports and studies on photocatalysts. [17][18][19][20][21][22][23][24][25][26][27] Metal sulfides are considered to be excellent photocatalysts due to the strong visible light absorption and sufficiently negative conduction band (CB). [28][29][30][31][32][33][34][35][36][37][38][39][40][41] Among them, CdIn 2 S 4 is a visible light-responsive catalyst with a bandgap of 2.2-2.6 eV, and is well-matched with the solar spectrum.…”
