“…The two peaks at 929.37 eV and 931.6 eV can be assigned to Cu2p 3/2 and 949.14 eV is for Cu2p 1/2 of CuO which is in good agreement with the previous literature reports. [32][33][34][35] The gap between Cu2p 3/2 and Cu2p 1/2 is 19.8 eV which is in agreement of standard value of 20.0 eV for CuO. 25 Moreover, the presence of two satellite peaks at 940.8 eV and 960.5 eV also indicate the existence of CuO on g-C 3 N 4 sheets.…”

An eco-friendly method for the oxidative transformation of alcohols to their corresponding carbonyl compounds by using g-C 3 N 4 @CuO as a photoactive heterogeneous catalyst has been developed. The catalyst was characterized by SEM-EDX, TEM, BET surface area measurements, powder XRD, FTIR, photoluminescence and UV-Vis spectroscopy. It was found to be very effective for the conversion of both primary and secondary alcohols into aldehydes and ketones with excellent yields using tert-butyl hydrogen peroxide (TBHP) as oxidant at room temperature in the presence of visible light in aqueous medium. The catalyst can be separated from the reaction mixture by simple centrifugation and reused up to five cycles without significant loss in activity.

“…Lately, it has attained significant attention in manganese doped-semiconductor materials in order to develop their physic-chemical behaviors and extend their efficient applications [3-5]. It has not only investigated the basic of magnetism, but also has huge potential in scientific features such as magnetic materials, bio & chemi-sensors, photo-catalysts, and absorbent nanomaterials [6-9]. Recently, very few articles are published based on transition-metal doped semiconductor nanomaterials synthesis and investigated the magnetic behaviors and potential applications only [10-13].…”

BackgroundSemiconductor doped nanostructure materials have attained considerable attention owing to their electronic, opto-electronic, para-magnetic, photo-catalysis, electro-chemical, mechanical behaviors and their potential applications in different research areas. Doped nanomaterials might be a promising owing to their high-specific surface-area, low-resistances, high-catalytic activity, attractive electro-chemical and optical properties. Nanomaterials are also scientifically significant transition metal-doped nanostructure materials owing to their extraordinary mechanical, optical, electrical, electronic, thermal, and magnetic characteristics. Recently, it has gained significant interest in manganese oxide doped-semiconductor materials in order to develop their physico-chemical behaviors and extend their efficient applications. It has not only investigated the basic of magnetism, but also has huge potential in scientific features such as magnetic materials, bio- & chemi-sensors, photo-catalysts, and absorbent nanomaterials.ResultsThe chemical sensor also displays the higher-sensitivity, reproducibility, long-term stability, and enhanced electrochemical responses. The calibration plot is linear (r2 = 0.977) over the 0.1 nM to 50.0 μM 4-nitrophenol concentration ranges. The sensitivity and detection limit is ~4.6667 μA cm-2 μM-1 and ~0.83 ± 0.2 nM (at a Signal-to-Noise-Ratio, SNR of 3) respectively. To best of our knowledge, this is the first report for detection of 4-nitrophenol chemical with doped Mn2O3-ZnO NPs using easy and reliable I-V technique in short response time.ConclusionsAs for the doped nanostructures, NPs are introduced a route to a new generation of toxic chemo-sensors, but a premeditate effort has to be applied for doped Mn2O3-ZnO NPs to be taken comprehensively for large-scale applications, and to achieve higher-potential density with accessible to individual chemo-sensors. In this report, it is also discussed the prospective utilization of Mn2O3-ZnO NPs on the basis of carcinogenic chemical sensing, which could also be applied for the detection of hazardous chemicals in ecological, environmental, and health care fields.

“…The maximum sorption capacity is 0.946 mmol g -1 . The loading capacity of the modified resin is more than reported for Rhizopus arrhizus and Chlorella vulgaris [40]. The static adsorption capacity for Fe(III) selective iron(III) ion uptake using CuO-TiO 2 nanostructure by ICP-OES was calculated to be 110.06 mg g −1 [41].…”

1-(3,4-Dihydroxybenzylidine)-2-acetylpyridinium chloride hydrazone (DAPCH) loaded on Duolite C20 has been investigated to be used in the elimination of Fe(III) from different media by batch and column techniques. The obtained modified resin (DC20-DAPCH) and the Fe(III) chelate were characterized by partial elemental analysis and IR spectra. The extraction isotherm was applied at different pH. Fe(III) was sorbed from aqueous solution at pH 3 and stripped using different concentrations of HCl. The maximum sorption capacity, the preconcentration factor and the detection limit of Fe(III) ion were 0.946 mmol g-1 , 300 and 1.0 ppb, respectively. The loaded resin was regenerated for at least 50 cycles. The utility of the modified resin was tested in water, ash coal, drugs, vitamin, kerosene and oil (food and petroleum) samples and showed RSD value of < 3% reflecting its accuracy and reproducibility. Iron(III) is highly extracted from mixtures containing different metal ions in the presence of thiocyanate and thiosulfate. The modified resin was found highly sensitive to Fe(III) than thiocyanate. Fe(II) may be eliminated from Fe(III) by controlling the pH. The method is successfully used for removing Fe(III) from crude phosphoric acid.
