ZnO Nanoparticles Embedded on a Reduced Graphene Oxide Nanosheet (ZnO−NPs@r‐GO) as a Proficient Heterogeneous Catalyst for a One‐Pot A3‐Coupling Reaction

“…[31] Though for organic transformations, [43][44] ZnO nanoparticles (NPs) have been established as solitary heterogeneous catalysts however, to the best of our knowledge, only few reports on rGO/ZnO nanocomposites as catalysts have been reported in the literature. [45][46][47] In continuation of our earlier work [48][49][50] , here in we report highly efficient ZnOÀ NPs@r-GO as a proficient heterogeneous catalyst and substantiated through various characterization tools. The accountability of rGO in ZnOÀ NPs@r-GO nanocatalyst is mainly providing tangible support which enhances the mechanical strength of the catalyst and also uniform dispersibility of ZnOÀ NPs.…”

Fe@g-C3N4: an effective photocatalyst for Baeyer–Villiger oxidation under visible light condition

“…45 As shown in the Fe 2p core level spectrum (Fig. 2), there are two main peaks at 712.44 eV and 725.78 eV that correspond to the multiplet splitting of high spin Fe 2p 1/2 and Fe 2p 3/2 , 46 which in turn split into two sub-peaks at 710.90 eV, 714.35 eV and 726.21 eV, 728.14 eV due to the difference in Fe oxidation states (Fe 2+ and Fe 3+ ). 45…”
