Photocatalysis, photoinduced enhanced anti-bacterial functions and development of a selective m-tolyl hydrazine sensor based on mixed Ag·NiMn2O4 nanomaterials

“…The end application of an electrochemical sensor should be the detection of real samples collected from various environmental sources. [50][51][52][60][61][62] Therefore, the assembled sensor based on Ag$NiMn 2 O 4 nanomaterial/binder/GCE was applied to analyze a number of samples obtained from various environmental sources, such as a PC baby bottle, PC water bottle, industrial waste effluent, and PVC food packaging bag; the resulting data obtained by applying the recovery method are summarized in Table 4. As illustrated in Table 4, the data were deemed to be quite acceptable.…”

“…The calcinations converted the carbonates of the sample into their oxides. 51,52 Three different single metal oxides (Ag 2 O, NiO and MnO) were also synthesized by the same method. All these oxides were calcined at 950 C. The reactions of the Ag$NiMn 2 O 4 synthesis can be summarized as below: For size analysis, a Williamson-Hall plot (eqn (1)) was used; the particle size was estimated to be 58.3 nm, where the standard deviation (ESD) of the peak tting is 0.00039 ( Fig.…”

“…Finally, the study indicated that trimetallic oxide nanocomposites are promising candidates for photocatalytic applications and environmental protection due to their nanostructure formation and perturbations of electronic energy levels. 51,52,[60][61][62] Anti-bacterial activity of the Ag$NiMn 2 O 4 nanocomposite…”

Fabrication of Novel and Potential Selective 4-Cyanophenol Chemical Sensor Probe Based on Cu-Doped Gd2O3 Nanofiber Materials Modified PEDOT:PSS Polymer Mixtures with Au/µ-Chip for Effective Monitoring of Environmental Contaminants from Various Water Samples

“…However, the electrochemical techniques are advantageous in terms of sensitivity, low-cost, response-time, and pretreatment of samples not required so suitable for on-field detection [ 22 , 23 , 24 , 25 , 26 ]. Thus electrochemical techniques gain substantial consideration in recent years [ 27 , 28 , 29 , 30 , 31 , 32 ]. Still, interference from similar chemicals is often observed in spectrophotometric techniques.…”

Development of an ultra-sensitive para-nitrophenol sensor using tri-metallic oxide MoO2·Fe3O4·CuO nanocomposites

“…This study was conducted to synthesize and characterize a tri-metal oxide from single metal oxides of interest, for exploring electrochemical sensor applications, because trimetallic oxide nanocomposites are promising systems for toxin sensors, photocatalytic applications and environmental safety, an efficient anti-bacterial agent against MDR bacteria, and industrial sterilization mediators. [12][13][14][15][16] Phenolic compounds and their derivatives are extensively used in the production of pharmaceuticals, dyes, pesticides, etc., and are known as severe environmental toxins. 17,18 They cause severe damage to organisms and plants.…”
