“…In general, the curves associated with the binding energy point out the chemical state of a concerned material. Figure 4 displays the complete XPS profile of the CdONPs, and the signals of O 1s and Cd 3 d core levels can be observed [40–44] . Other signals related to any impurities were not detected which proves the purity of the sample at XPS limit.…”

“…Here, Cd 3 d core levels spectra of these nanoparticles show two peaks corresponding to Cd 3 d 5/2 and Cd 3 d 3/2 components. This spectrum consists of a spin‐orbit doublet which is an exclusive gaussian‐shape doublet (Figure 4(b)) [40–44] . The peaks corresponding to the Cd 3 d 5/2 and Cd 3 d 3/2 components are located at 405.31 eV and 412.03 eV respectively with spin‐orbit splitting value of 6.72 eV.…”

“…This spectrum consists of a spin-orbit doublet which is an exclusive gaussian-shape doublet (Figure 4(b)). [40][41][42][43][44] The peaks corresponding to the Cd 3d 5/2 and Cd 3d 3/2 components are located at 405.31 eV and 412.03 eV respectively with spin-orbit splitting value of 6.72 eV. These results clearly reveal that CdONPs are composed by a single CdO phase, and no secondary phases are appeared associated with Cd 4 + and Cd 2 + ions.…”

An innovative and environmentally sustainable approach is presented for the synthesis of cadmium oxide nanoparticles (CdONPs), leveraging the leaf extract of the pigeon pea plant (Cajanus cajan) as both reductive and capping agents. This environmentally friendly heterogeneous CdONPs was meticulously characterized through FT‐IR, PXRD, HR‐TEM, SEM‐EDAX, XPS and UV‐Vis spectroscopic analyses. These NPs were subsequently applied to facilitate the three‐component Biginelli reaction using ethyl acetoacetate, urea, and substituted benzaldehydes for producing dihydropyrimidone derivatives in good to excellent yield. The methodology was tested for different aldehydes containing electron‐withdrawing and electron‐donating groups. The catalyst demonstrated consistent performance over approximately five cycles, exhibiting negligible loss in yield and catalytic potential. The proposed mechanistic pathway of the reaction was elucidated through intermediate mass analysis and further validated by Density Functional Theory (DFT) calculations and catalytic surface adsorption studies.
