“…As they usually are magnetizable species, NCs are easily separable from the reaction medium due to their insolubility [ 23 ]. According to the existing literature [ 24 , 25 , 26 ], relevant examples of NCs include nanoparticles containing cobalt [ 27 , 28 , 29 , 30 , 31 ], gold [ 32 , 33 , 34 ], iron [ 35 , 36 , 37 , 38 , 39 , 40 ], nickel [ 41 , 42 , 43 , 44 ], palladium [ 45 , 46 , 47 , 48 , 49 , 50 ], and platinum [ 42 , 51 , 52 , 53 ]. Among the most diverse uses of NCs are biodiesel production [ 54 , 55 , 56 , 57 , 58 , 59 , 60 , 61 , 62 , 63 ], dyeing [ 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 …”
