• Physical properties: Neodymium is the third most abundant rare-earth element in the Earth’s crust (24 ppm). Itis reactive with moist air and tarnishes in dry air, forming a coating of Nd3O3, an oxide witha blue tinge that flakes away, leaving bare metal that then will continue to oxidize. Its melting point is 1,021°C, its boiling point is 3,074°C, and its density is 7,01 g/cm3.
• Uses: Neodymium salts, electronics, alloys, colored glass, (especially in astronomical lenses and lasers), to increase heat resistance of magnesium, metallurgical research, yttrium-garnet laser dope, gas scavenger in iron and steel manufacture Misch metal is composed of about 18% neodymium, from which cigarette-lighter flints aremade. Because neodymium absorbs the yellow “sodium” line in the visible light spectrum, itcan be added to glass to produce violet-, red-, or gray-colored glass. Neodymium glass is usedto calibrate spectrometers and other optical devices in astronomical and laboratory observationinstruments. It is also used in the production of artificial rubies used in lasers. Its salts areused as pigments for ceramic enamels and glazes. Neodymium is magnetic and is used in many of the most powerful magnets in the world.Some types of steel contain up to 18% neodymium as an alloy. It is also used as a color forTV tubes and as a tint for eyeglasses. Neodymium, plasma standard solution is used as a standard solution in analytical chemistry and atomic absorption spectroscopy. It is also used as a single-element standard solution for plasma emission spectrometry.

Preparation and photocatalytic activity of Nd-modified TiO₂ photocatalysts: Insight into the excitation mechanism under visible light

10.1016/j.jcat.2017.07.017

The research investigates the synthesis, characterization, and photocatalytic properties of neodymium (Nd)-modified titanium dioxide (TiO2) nanoparticles prepared via the hydrothermal method. The study aims to enhance the visible light photocatalytic activity of TiO2 by doping it with Nd in the range of 0.1 to 1.0 mol%. The photocatalysts were characterized using various techniques, including diffuse reflectance spectroscopy (DRS), scanning electron microscopy (SEM), X-ray fluorescence (EDX), Brunauer–Emmett–Teller (BET) method, X-ray powder diffraction analysis (XRD), X-ray photoelectron spectroscopy (XPS), and photoluminescence spectroscopy (PL). The results showed that the Nd-modified TiO2 exhibited high photocatalytic activity under visible light, with the highest activity observed for the sample modified with 0.1 mol% Nd3+. This sample had a surface area of 124 m2/g and an average crystal size of 10.9 nm. The study also explored the excitation mechanism under visible light and concluded that the up-conversion process was not responsible for the degradation of phenol under visible light irradiation. The enhanced photocatalytic activity was attributed to the increased adsorption sites, BET surface area, decreased crystallite size, and prevention of electron-hole recombination.
