“…1b). 35,36 The shi in the PXRD peak position due to the lattice contraction occurred aer the Pd incorporation into the Co lattice, driving the formation of the CoPd alloy at elevated temperatures under the carbonization conditions. Similar observations were claimed in earlier literature conrming the successful formation of the CoPd alloy in Co 1−x Pd x @N-C catalysts.…”

“…The negative shi in the binding energy of Pd is due to the more electron negativity of Pd than Co, indicating the electron transfer from Co to Pd, suggesting the successful formation of the CoPd nanoalloy. 35,36,40 The C 1s of Co 8 Pd 2 @N-C was deconvoluted to C]C, C-C/C]N, and C-N/C-O that appeared at 284.5 eV, 285.3 eV, and 286.4 eV, respectively (Fig. 2e).…”

“…Generally, heteroatom-doped OMC materials can act as a stabilizing agent and supportvarious nanoparticles. [35,[54][55][56] There are a handful of reports about using gold nanoparticles as catalysts in the synthesis of propargylamine derivatives via a three-component A3 coupling reaction. In 2010, Vinu and coworkers introduced a gold nanoparticle supported on a mesoporous carbon nitride as a highly efficient catalyst for A3 coupling reaction between benzaldehyde, piperidine, and phenylacetylene, in which the reaction was carried out using 0.45 mol% of catalyst, in toluene at 100 C to give a corresponding propargylamine in 96.2% isolated yield and 64.4% selectivity.…”

Gold nanoparticles immobilized on egg yolk biomass derived N-doped ordered mesoporous carbon (Au@OMC) were prepared by nano-casting process using SBA-15 template and carbonization, followed by removing silica moiety of SBA-15, and then immobilization of Au nanoparticles. Synthesized Au@OMC was characterized using XRD, SEM, TEM, EDS, XPS, DLS, and BET analysis, revealing the successful immobilization of Au nanoparticles on the surface of OMC material. Au@OMC exhibited high catalytic activity for threecomponent A3 coupling reaction between aldehydes, amines, and phenylacetylene to furnish propargyl amines. Also, KA2 coupling reaction between ketones, amines, and phenylacetylene was efficiently performed using Au@OMC catalytic system. Recyclability studies indicated that the recovered catalyst can be reused for five runs without considerable changes in the catalytic activity. The leaching experiment revealed that there is no Au catalyst leaching into the reaction solution.

From the most classic carbon materials (CMs) to the advanced ones, all of them integrate a promising catalyst set in terms of sustainability and energy efficiency for a greener future. Different synthetic strategies concerning to the catalytic synthesis of relevant N‐containing heterocycles are herein described to address the great potential of the referred catalysts flying over what has been done and all that remains to be done. Current trends in this field involve structure‐activity relationships establishment also considering the reaction mechanisms understanding and the identification of active catalytic sites, as function of both experimental datasets, emphasizing on operando characterization techniques, and theoretical studies which will significantly contribute to the design of custom‐made catalysts as a new horizon.
