Novel magnetic semiconductor Na₂Fe₂Ti₆O₁₆: synthesis, double absorption and strong adsorptive ability

Abstract

Na2Fe2Ti6O16 demonstrates a strong adsorptive ability towards methylene blue and easy separation from aqueous solution due to its high saturation magnetization.

Enhanced piezo-photocatalytic performance by piezoelectric and visible light photoexcitation coupling through piezoelectric Na0.5Bi0.5TiO3 micron crystals

“…The binding energy peak located at 1070.75 eV attributes to Na + ions in the sample. 41 Fig. 2(c) reveals the Bi 4f spectrum, where two characteristic binding energy peaks located at 158.85 eV (Bi 4f 7/2 ) and 164.15 eV (Bi 4f 5/2 ) correspond to Bi 3+ chemical state in the sample.…”

A Highly Sensitive and Selective Probe for the Colorimetric Detection of Mn(II) Based on the Antioxidative Selenium and Nitrogen Co-Doped Carbon Quantum Dots and ABTS•+

“…As seen in Supplementary Figure 1C, there were two deconvoluted peaks at 530.8 and 531.9 eV, representing the presence of C-O and C=O/O-H bonds, respectively, in the high-resolution XPS spectrum of O 1s spectrum (Zhang et al, 2015;Bankoti et al, 2017). It can be seen from Supplementary Figure 1D that the deconvoluted peak at 1,071.3 eV in the Na 1s XPS spectrum was attributed to Na + (Guo et al, 2017). The weak deconvoluted peak located at 53.2 eV was attributed to Se 2− in the high-resolution XPS spectrum of Se 3d spectrum in Supplementary Figure 1E ( Ray et al, 2013), illustrating the existence of selenium elements in Se/N-CQDs.…”

Adsorption Behavior of Congo Red onto Barium-Doped ZnO Nanoparticles: Correlation between Experimental Results and DFT Calculations

“…1−3 Organic pollutants in water such as dyes, including Congo Red (CR), have grown dangerous to the surroundings and human health, owing to the formed organic compounds' resistance to biodegradation. 4 CR has carcinogenic and mutagenic effects on animals and humans. 5 It is principally produced from plastic, paper, textile, printing, and dyeing industries 6 and is a water-soluble benzidine-based azo dye, involving a complex structure (C 32 H 22 N 6 Na 2 O 6 S 2 ).…”

“…Nowadays, the increased manufacture of organic materials employed in various applications results in rising amounts of residuals discharged into the environment. − Organic pollutants in water such as dyes, including Congo Red (CR), have grown dangerous to the surroundings and human health, owing to the formed organic compounds’ resistance to biodegradation . CR has carcinogenic and mutagenic effects on animals and humans .…”
