“…Metal nanoparticles (MNPs) are effective catalysts for a variety of reactions. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] NPs of metal oxides also show catalytic activity in several reactions (oxidation, reduction, coupling, condensation, etc. ), [20][21][22][23] and they, in combination with MNPs, can act as active cocatalysts, [24][25][26][27][28][29][30][31][32] giving to the nanocomposite bifunctionality or synergistic effects.…”
