“…It is easy to cause an explosion, which can bring about great damage or disaster when the concentration is higher than 5% (in volume) in air. [1][2][3][4] In order to decrease the risk, a practicable technique is desired for detection of CH 4 at a low concentration to provide early alarm. On the other hand, CH 4 is difficult to detect via traditional methods due to its natural properties, such as being colorless, tasteless and odorless.…”

“…This hybrid also has potential for the fabrication of biogas sensors and electrochemical sensors. The ZnO NPs decorated on graphene act not only as spacers between the GSs, but also to enhance the sensitivity towards common industrial toxin gases like CO, NH 3 , NO [262], methane [263], NO 2 [264], formaldehyde [265–266], H 2 [267], and also to humidity [268]. Furthermore, this hybrid system is used for the photocatalytic reduction of Cr(VI) [269–270].…”

Single layer graphite, known as graphene, is an important material because of its unique two-dimensional structure, high conductivity, excellent electron mobility and high surface area. To explore the more prospective properties of graphene, graphene hybrids have been synthesised, where graphene has been integrated with other important nanoparticles (NPs). These graphene–NP hybrid structures are particularly interesting because after hybridisation they not only display the individual properties of graphene and the NPs, but also they exhibit further synergistic properties. Reduced graphene oxide (rGO), a graphene-like material, can be easily prepared by reduction of graphene oxide (GO) and therefore offers the possibility to fabricate a large variety of graphene–transition metal oxide (TMO) NP hybrids. These hybrid materials are promising alternatives to reduce the drawbacks of using only TMO NPs in various applications, such as anode materials in lithium ion batteries (LIBs), sensors, photocatalysts, removal of organic pollutants, etc. Recent studies have shown that a single graphene sheet (GS) has extraordinary electronic transport properties. One possible route to connecting those properties for application in electronics would be to prepare graphene-wrapped TMO NPs. In this critical review, we discuss the development of graphene–TMO hybrids with the detailed account of their synthesis. In addition, attention is given to the wide range of applications. This review covers the details of graphene–TMO hybrid materials and ends with a summary where an outlook on future perspectives to improve the properties of the hybrid materials in view of applications are outlined.

“…In general, using two‐dimensional (2‐D) materials is an effective way to improve the nanoparticles‐based sensor response, because two‐dimensional (2‐D) materials can not only prevent the agglomeration of nanoparticles, but also enhance the electrical properties ,. Zhang et al.…”

“…Zhang et al. synthesized the ZnO nanocrystalline decorated reduced graphene oxide via a hydrothermal process, and the nanocomposites exhibited unique advantages in methane gas sensing, such as outstanding repeatability and good selectivity . For the past few years, graphitic carbon nitride (g‐C 3 N 4 ), a 2‐D π‐conjugated polymeric, metal‐free, mild band gap (2.7 eV) semiconductor has emerged as an attractive material for various scientific application .…”

The nanocomposites of g‐C3N4 nanosheet decorated magnesium ferrite nanoparticles were synthesized by a facile solvothermal method. X‐ray diffraction (XRD), field‐emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM) and thermal gravimetric analysis and differential scanning calorimeter (TG‐DSC) techniques were used to characterize the structure and morphology of the as‐prepared nanocomposites. The results indicated that the MgFe2O4 nanoparticles were highly dispersed on the surface of the g‐C3N4 nanosheet. The gas‐sensing properties of the samples were tested, and the response value (Ra/Rg) of the MgFe2O4/g‐C3N4 nanocomposite with 15 wt.% g‐C3N4 content‐based sensor to 500 ppm of ethanol was 112 at 300 °C, which is 5 times higher than that of pure MgFe2O4. Moreover, the MgFe2O4/g‐C3N4‐15‐based sensor showed impressive selectivity, fast response and recovery characteristics, and good linearity in range of ethanol concentration (10–500 ppm).
