“…The characteristic hexagonal Ag2O peaks of (110), ( 111), ( 200), ( 211), (220), and (221) planes were shown at 27.8°, 32.2°, 38.0°, 46.1°, 54.4°, and 57.4°, respectively. The XRD pattern perfectly matched the hexagonal Ag2O and tetragonal SnO2 crystal structures [33,34]. This indicated that the material includes both Ag2O and SnO2 according to the XRD spectrum of SnAg2O3.…”

Silver oxide-doped tin oxide (SnAg2O3) nanoparticles were synthesized and different spectroscopic techniques were used to structurally identify SnAg2O3 nanoparticles. The reduction of 4-nitrophenol (4-NP), congo red (CR), methylene blue (MB), and methyl orange (MO) was studied using SnAg2O3 as a catalyst. Only 1.0 min was required to reduce 95% MO; thus, SnAg2O3 was found to be effective with a rate constant of 3.0412 min−1. Being a powder, SnAg2O3 is difficult to recover and recycle multiple times. For this reason, SnAg2O3 was coated on adhesive tape (AT) to make it recyclable for large-scale usage. SnAg2O3@AT catalyst was assessed toward MO reduction under various conditions. The amount of SnAg2O3@AT, NaBH4, and MO was optimized for best possible reduction conditions. The catalyst had a positive effect since it speed up the reduction of MO by adding more SnAg2O3@AT and NaBH4 as well as lowering the MO concentration. SnAg2O3@AT totally reduced MO (98%) in 3.0 min with a rate constant of 1.3669 min−1. These findings confirmed that SnAg2O3@AT is an effective and useful catalyst for MO reduction that can even be utilized on a large scale for industrial purposes.

“…The sharpness and intense diffraction peaks of Imp‐Ni‐Sb‐SnO 2 , ED‐Ni‐Sb‐SnO 2 , and ED‐Sb‐SnO 2 can be well assigned to tetragonal rutile SnO 2 phase (JCPDS 41–1445). It can be found that the intense diffraction peaks of samples located at 27.1°, 34.2°, 38.6°, 52.2°, 55.1°, 70.9° which can be attributed to (110), (101), (200), (211), (220), and (202) crystal planes of tetragonal rutile SnO 2 phase 20 . In addition, the diffraction peak of Imp‐Ni‐Sb‐SnO 2 , ED‐Ni‐Sb‐SnO 2 , and ED‐Sb‐SnO 2 are slightly shifted towards higher angles when compared to the Ed‐SnO 2 and standard card (JCPDS 41–1445), indicating the Sb 5+ (0.62 Å) with a smaller radius was successfully doped into the SnO 2 (0.69 Å) crystal structure 21 .…”

Electrochemical synthesis of green oxidants O3 and H2O2 is valuable for applications, but challenges persist in enhancing the O3 and H2O2 generation activity and combined application. Herein, we modulate the surface Ni active sites and oxygen vacancy defects content in Ni‐Sb‐SnO2 electrocatalysts to enhance selectivity for electrochemical ozone generation (EOP) and two‐electron electrochemical oxygen reduction reactions (2e− ORR). The Ni active sites and oxygen vacancy defects enriched electrocatalysts resulting in an ozone faradaic efficiency of 48.1%, while non‐enriched electrocatalyst obtained 90% selectivity for H2O2. Theoretical calculations revealed that Ni‐Sb‐SnO2 efficiently captures O2 with defective Ovac2 stabilize intermediates, facilitating O3 and H2O2 synthesis. Moreover, concerted EOP and 2e− ORR enable concurrent generation of O3 and H2O2 for efficient synergistic degradation of organic pollutants, while attenuating the energy demands of the electrolyzer. This study provides an appealing strategy for simultaneous production of O3 and H2O2 with applications in wastewater treatment.

PVP/CMC/50%ZnS‐50%SnO2 blends were formed by solid state reaction, sol‐gel methods and casting technique. The structure and the crystallite size of the nanofillers (ZnS and SnO2) were examined using x‐ray diffraction technique (XRD). The effect of laser irradiation energies compared to the proportions of loaded nanofillers on the films internal structure and morphology was studied using XRD. The high miscibility among blends has been confirmed through Fourier transform infrared spectroscopy (FTIR). The energy dispersive x‐ray spectroscopy (EDS) analysis proved the presence of the nanocomposite polymer blends constituent atoms. The blends surface morphology has been investigated through scanning electron microscope (SEM). The dual effect of both different laser energies and oxygen atoms content simultaneously, on the linear and nonlinear optical parameters of nanocomposite films were explored as well. Results showed that, the laser irradiation energy process has the highest enhancement on the optical properties. The optical band gap (Eg) values were reduced from 4.8 eV (in the case of unirradiated blend) to 3.5 eV (for blends irradiated with 150 mJ/cm2) for allowed direct transitions, but for allowed indirect transitions Eg decreased from 3.3 eV (for unirradiated) to 2.2 eV (for irradiated with 150 mJ/cm2).Highlights A comparative discussion upon the effect of excess oxygen atoms has been represented. A dominant effect for the laser exposure compared to both the particle size and excess oxygen atoms. The variations of the nanocomposite films structural and optical features were promising.
