Enhanced photocatalytic hydrogen production activity via dual modification of MOF and reduced graphene oxide on CdS

Abstract

A Ternary composite UiO-66/CdS/1% reduced graphene oxide (RGO) was successfully prepared, with a photocatalytic hydrogen evolution rate 13.8 times as high as that of pure commercial CdS. It shows great advantages over the perfect composite photocatalyst-P25/CdS/1%RGO.

Metal–Organic Framework (MOF) Compounds: Photocatalysts for Redox Reactions and Solar Fuel Production

“…[122] As commented in the previous Sections,the presence of -NH 2 groups in the linker introduces an additional absorption band in the MOF that makes possible visible-light excitation. [91]). [92] Upon irradiation (l > 420 nm), continuous H 2 production was observed from the beginning of the irradiation period, and the total evolution of H 2 reaches to 33 mmol after 9h showing that Pt/NH 2 -MIL-125(Ti) acts as av isible-light-responsive photocatalyst.…”

A new visible light active multifunctional ternary composite based on TiO2–In2O3 nanocrystals heterojunction decorated porous graphitic carbon nitride for photocatalytic treatment of hazardous pollutant and H2 evolution

“…As a result, the enhanced photoelectrochemical properties of TiO 2 -In 2 O 3 @g-C 3 N 4 ternary composites could be attributed to the enhancement separation efficiency of photoinduced electrons and holes, which might attributed to the synergetic effect of TiO 2 , In 2 O 3 and g-C 3 N 4 . Furthermore, the larger specific surface area could not only lead to more efficient use of the light source and enhanced light harvesting but also provide more catalytic sites [82].…”

Metal Organic Frameworks: A New Generation Coordination Polymers for Visible Light Photocatalysis

“…For instance Surface Plasmon Resonance [SPR] enabled metals like Ag, Au, Pd, Pt were considered by many groups for expanding the spectrum of the TiO 2. On the other side conducting carbon materials like graphene, graphene oxide [GO], reduced graphene oxide [RGO] were hybridised with it for promoting visible light spectrum and prolonging the life time of charge carriers . Apart in recent years graphitic carbon [g‐C 3 N 4 ] with heptazine units replaced the metal oxide due to their stunning visible light utilising ability and low toxic nature .…”
