“…These nanocrystals under hydrothermal conditions with SDS then grow along the c -axis, forming one-dimensional morphology because of the ionic effects and constraints of space inside the micellar cavity (Scheme S2). , The EDTA as a chelating agent forms CeV NB. EDTA, which is a cationic chelating agent ([EDTA] 4– ), forms a chelating compound, i.e., [CeEDTA] − , when introduced to Ce 3+ .…”

Growing demand for benzaldehyde in recent years has prompted researchers to explore an environmentally sustainable process to synthesize it from abundant materials to replace the conventional toluene chlorination method. In that direction, benzaldehyde synthesis from the catalytic oxidative cleavage of styrene is attractive, as styrene is cheap and millions of tons are produced per year. Herein, cerium vanadate (CeVO4) is demonstrated as an outstanding catalyst for the synthesis of benzaldehyde from styrene oxidation at 80 °C. The particle-shaped (CeV NP), rod-shaped (CeV NR), and bar-shaped (CeV NB) nanostructured CeVO4 (CeV) are synthesized by varying the surfactants. All the catalysts exhibit favorable properties such as high surface area, surface charge, acidity, and oxygen vacancy, which are correlated to their catalytic performance. Among the morphologies, CeV NP shows the highest styrene conversion (99.5%) along with the highest benzaldehyde selectivity (84.2%). The nonleaching of catalyst further confirms the heterogeneous reaction process, which makes it a strong candidate for industrial purposes.

Silver nanoparticles (AgNp) have been widely developed, one of which is an antibacterial agent. The ability of AgNp to inhibit bacteria is unquestionable. These properties and characteristics can be studied further by adding defects. The defect used is Cdots from tangerines. Cdots are new materials that can be synthesized from natural materials and have unique properties. AgNp itself was synthesized by the chemical reduction method with sodium citrate as a reducing agent, while Cdots was synthesized by hydrothermal method. The results of the synthesis were analyzed using the Fourier Transform Infrared (FT-IR) method. Absorption appears at a wave number of 1637 cm-1 which indicates the presence of C=C, C=O bonds which are characteristic of Cdots. For AgNp, absorption appears at a wave number of 593.11 cm-1 which indicates the presence of Ag vibrations. Analysis with UV-Vis spectrophotometer gave the results at a wavelength of 431 nm absorbance AgNp-Cdots of 0.723 and a wavelength of 422 nm AgNp absorbance of 0.285. The results of the Particle Size Analyzer (PSA) analysis showed that AgNp-Cdots had an average size of 38.7 nm with a PI of 0.499 and pure AgNp of 51.8 nm with a PI of 0.566. Antibacterial activity of AgNp-Cdots against E. coli bacteria showed an inhibition zone of 2 mm while AgNp showed an inhibition zone of 5 mm.

“…This effect was attributed to silver's Coulombic advantage that compensates for the fact that Au is a ''more noble'' metal [20]. It is also reported that Ag nanoparticles can take different shape in high SDS concentration [21]. Laser ablation studies have shown that there is no significant effect of SDS concentration on Au nanoparticles [5].…”
