Tailored MXene-derived nano-heterostructure oxides for peroxymonosulfate activation in the treatment of municipal wastewaters.

Nowadays, in the field of environmental protection, a huge effort is focused on efficient and sustainable processes to treat wastewaters. The current study emphasizes the photocatalytic performance of TiNbO, a nano-heterostructure material derived from the oxidation of (TiNb)CT MXene. The TiNbO nano-heterostructure exhibited remarkable performance in the degradation of caffeine (CAF) and sulfamethoxazole (SMX) under UVA irradiation in the presence of peroxymonosulfate (PMS).

MXene-Derived Oxide Nanoheterostructures for Photocatalytic Sulfamethoxazole Degradation.

Herein, we report for the first time the use of ternary oxide nanoheterostructure photocatalysts derived from (Nb , Ti )CT MXene in the treatment of water. Three different compositions of binary MXenes, viz., (TiNb)CT , (TiNb)CT , and (TiNb)CT (with T = OH, F, and Cl), were used as single-source precursor to produce TiNbO -3:1, TiNbO -1:1, and TiNbO -1:3 by controlled-atmosphere thermal oxidation.

Structural and Magnetic Properties of Inverse-Heusler MnFeSi Alloy Powder Prepared by Ball Milling.

Ternary MnFeSi alloy was synthesized from pure elemental powders by mechanical alloying, using a high-energy planetary ball mill. The formation of an inverse-Heusler phase after 168 h of milling and subsequent annealing at 1173 K for 1.5 h was confirmed by X-ray diffraction.
