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...

The development of homogeneous photoredox catalysts in radical coupling reactions has been truly phenomenal, and the generation of new carbon–carbon bonds in an atom economical manner is a continuous pursuit in synthetic organic chemistry. This enables the production of many pharmaceutical compounds and bio-active molecules. The use of photoredox catalysts has quickly realized the huge potential in organic synthesis to afford facile coupling reactions enabled by photo-energy. Many excellent examples have been seen in the literature, including couplings of carbonyl-a-radicals [ 1 ] and ketyl radicals (e.g. the Pinacol Coupling Reaction, PCR) [ 2 ]. However, despite many successful applications of photoredox catalysts in radical coupling reactions, with some exceptions the scarce and expensive ruthenium (Ru) and iridium (Ir)-based homogeneous catalysts are predominantly used, which are difficult to isolate and recycle at the end of the reactions. Over the past few years, engineering of g...
