During the recent years, water and air pollutions are mainly caused in the fields such as industry, urban effluents, and transportation in worldwide over major cities. Serious environmental pollution, and related issues and accelerated global warming can be attributed due to the rapid consumption of fossil fuels, the increasing population, and the rapid development of the economy. Thus, the development of innovative and renewable environmental remediation materials is becoming increasingly  one. Recently, many researchers are focusing on “A noble metal/ MoS 2 nanocomposites (NCs)” which can induce local surface Plasmon resonance (LSPR) for activating the photoelectrocatalysis of hydrogen and enhancing the light emission or absorption of MoS 2 . Moreover, the LSPR can generate surface-enhanced Raman scattering (SERS), which can be used in many applications, particularly it is used in chemical sensing and biological applications. Over the last two decades, magnetic materials have em...
