“…This indicates that the doping does not affect the formation of the nal product but alters its morphology. The crystal grain size (D) of the CuO (111) crystal plane in CuO, Sn-CuO, and Sn-In-CuO can be calculated using the well-known Debye-Scherrer equation [26,27] : 6 In this equation, D represents the crystallite size (nm), K is a constant equal to 0.9, λ is the X-ray wavelength, β is the full width at half maximum (FWHM) of the diffraction peak, and θ is the diffraction angle given in degrees. As shown in Table 1, the crystallite sizes of the CuO (111) crystal plane in CuO, Sn-CuO, and Sn-In-CuO are 16.51 nm, 11.59 nm, and 10.80 nm, respectively, which are consistent with the corresponding XRD diffraction patterns.…”

Electrocatalysis serves as a highly effective approach to both mitigate greenhouse gas emissions and produce high-value chemicals. Copper-based catalysts have garnered considerable attention due to their immense potential in this domain, improving the selectivity and activity through optimizing preparation strategies is of paramount importance. In this study, mechanochemical method was rst used for preparing copper-based composite metallic oxide electrocatalysts. Spherical CuO, Sn-CuO, and Sn-In-CuO catalysts were prepared and their electrochemical carbon dioxide reduction performance was evaluated.Among them, the Sn-In-CuO catalyst demonstrated the best performance in reducing carbon dioxide to carbon monoxide products. Within the potential range of -0.6 V to -1.1 V vs. RHE, the Faradaic e ciency of carbon monoxide product was consistently above 93.56%, with a maximum Faradaic e ciency of 96.11% achieved at -0.9 V vs. RHE. Sn-In-CuO also exbibts good stability with high Faradaic e ciency of carbon monoxide above 87.97% for a duration of 6 hours under the potential of -0.6 V vs. RHE in a 0.1 M KHCO 3 electrolyte. The excellent performance is speculated to be attributed to the generation of a large number of defects and the introduction of metal doping, which increases the number of active sites through the mechanochemical method.

“…This study focused on the potential use of SnO 2 and Zn-doped SnO 2 as functional nanomaterial fillers for food packaging materials. SnO 2 , an n-type semiconductor, has been used in gas sensing, solar cells, energy devices, photovoltaics, photocatalysis, , and biomedical applications. , Since its lattice structure, chemical bond length, and electrical band gap values are identical to TiO 2 , SnO 2 has been examined as a potential photocatalyst due to its advantages, such as low cost, eco-friendliness, and nontoxicity. , Due to its wide band gap (3.7 eV), SnO 2 displays visible light transparency and UV absorption . SnO 2 works well as an electron acceptor and is reported to have high conductivity .…”

SnO 2 and Zn-SnO 2 nanoparticles were prepared by chemical precipitation, and the rutile phase of SnO 2 was confirmed through X-ray diffraction studies. X-ray photoelectron spectroscopy (XPS) confirmed the doping of SnO 2 with Zn and elucidated the surface chemistry before and after doping. The average sizes of SnO 2 and Zn-SnO 2 nanoparticles determined using TEM were 3.96 ± 0.85 and 3.72 ± 0.9 nm, respectively. UV−visible and photoluminescence spectrophotometry were used to evaluate the optical properties of SnO 2 and Zn-SnO 2 nanoparticles, and their energy gaps (E g ) were 3.8 and 3.9 eV, respectively. The antibacterial activity of these nanoparticles against Salmonella enterica and Staphylococcus aureus was evaluated under dark and light conditions. Antibacterial activity was higher in light, showing the highest activity (99.5%) against S. enterica. Carboxymethylcellulose (CMC)/agar-based functional composite films were prepared by adding different amounts of SnO 2 and Zn-SnO 2 nanoparticles (1 and 3 wt % of polymers). The composite film showed significantly increased UV barrier properties while maintaining the mechanical properties, water vapor barrier, and transparency compared to the neat CMC/agar film. These composite films showed significant antibacterial activity; however, the Zn-SnO 2 -added film showed stronger antibacterial activity (99.2%) than the SnO 2 -added film (15%).
