Facile synthesis of MoS 2 /rGO-MOF hybrid material as highly efficient catalyst for hydrogen evolution

Graphene-Based Metal–Organic Framework Hybrids for Applications in Catalysis, Environmental, and Energy Technologies

“…Mo-based materials are seen as particularly promising precious-metal-free HER catalysts, and MOF/graphene hybrids containing molybdenum have therefore also been examined as potential HER electrocatalysts. For instance, nanosized MoS 2 was incorporated into a Cu-MOF based hybrid, HKUST-1/rGO, via a solvothermal process, yielding a composite that benefited from the high activity of MoS 2 , the high surface area and porosity of the MOF, and the high electrical conductivity of rGO . Similarly, MoP encapsulated in P-doped C nano-octahedrons supported on rGO, fabricated by carbonizing polyoxometalate-based MOFs with subsequent phosphidization, exhibited the advantages of all its different components and achieved excellent HER performance and stability in acidic media …”

Recent Electrochemical Applications of Metal–Organic Framework-Based Materials

“…Zhu and co-workers synthesized the MoS 2 /RGO-MOF hybrid material by employing a two-phase hydrothermal and solvothermal procedure after loading MoS 2 onto the surface of a Cu-MOF (Cu-BTC) and GO hybrid and then examined its use as an electrocatalyst for HER, finding this composite material shows a small onset potential equal of 60 mV and a Tafel slope of 36 mV dec –1 . In this system, the enhanced catalytic activity can likely be attributed to the greater specific surface areas of the mesoporous structure of the GO-MOF hybrid, as well as the synergetic effects between the GO-MOF matrix and the MoS 2 NCs …”

“…In this system, the enhanced catalytic activity can likely be attributed to the greater specific surface areas of the mesoporous structure of the GO-MOF hybrid, as well as the synergetic effects between the GO-MOF matrix and the MoS 2 NCs. 170 Nivetha and co-workers synthesized two Fe-based MOF catalysts, MIL-53(Fe)/dehydrated, and MIL-53(Fe)/hydrated, using a solvothermal procedure and then examined their use in HER. Although MIL-53(Fe)/dehydrated and MIL-53(Fe)/ hydrated both show appropriate electrocatalytic activities, MIL-53(Fe)/hydrated demonstrates a better exchange current density relative to that of MIL-53(Fe)/dehydrated (2.5 × 10 −4 mA cm −2 and 1.6 × 10 −4 mA cm −2 , respectively).…”

A novel sensing layer based on metal–organic framework UiO-66 modified with TiO2–graphene oxide: application to rapid, sensitive and simultaneous determination of paraoxon and chlorpyrifos

“…[35][36][37] Notably, the broadened diffraction peaks indicated that T on the surface of GO (in the TG@UiO-66 matrix) has a low degree of crystallinity. 38 Furthermore, the absence of GO diffraction is due to the insertion of UiO-66 between TG layers that effectively reduces the van der Waals binding energy between the GO sheets and improves the layer exfoliation and also high dispersion of TG layers during the nanocomposite preparation can be another reason for this observation. [39][40][41] These concepts can be verified by FT-IR and SEM analyses.…”
