Mechanistic insights into defect chemistry and tailored photoluminescence and photocatalytic properties of aliovalent cation substituted Zn_0.94M_0.06−xLi_xO (M: Fe³⁺, Al³⁺, Cr³⁺) nanoparticles

Abstract

In this work, we demonstrate the microwave assisted solution combustion synthesis of aliovalent cations substituted Zn0.94M0.06-xLixO (M: Fe3+, Al3+, Cr3+) nanoparticles. The structural features, photoluminscent and photocatalytic properties were characterized...

A review on the synthesis of metal oxide nanomaterials by microwave induced solution combustion

“…The results showed that the photodegradation efficiencies of CZO (6 mol% Gr 3+ -doped ZnO), AZO (6 mol% Al 3+ -doped ZnO), and L3AZO (1.5 mol% Li + -ion co-doped AZO) catalysts were higher compared with the photodegradation efficiencies of ZnO catalysts (89%). 66 Kanithan et al group used nickel nitrate, iron nitrate, and magnesium nitrate as oxidants and arginine as fuel to synthesize undoped nickel ferrite spinel (NiFe 2 O 4 ) and magnesium doped nickel ferrite spinel (Ni 1− x Mg x Fe 2 O 4 ). The undoped NiFe 2 O 4 has a single-phase cubic spinel structure with an average crystallite size between 20 and 35 nm, while the magnesium-doped NiFe 2 O 4 also has a cubic spinel structure.…”

Enhanced photocatalytic activity in ZnO nanoparticles developed using novel Lepidagathis ananthapuramensis leaf extract

“…Even though both are effectively used, ZnO NPs are generally a better candidate for photocatalytic degradation of pollutants because of their high stability, non-toxicity, 15 single oxidation state, natural abundance, suitable band gap 16 and better biocompatibility. 17 ZnO is a wide bandgap (3.37 eV) 18 semiconductor which acts as an excellent photocatalyst for the decomposition of water pollutants. 19 One of the top most priorities of the present-day research is for clean water in order to retain the ecosystem.…”

Comprehensive Insights into Synthesis, Structural Features, and Thermoelectric Properties of High-Performance Inorganic Chalcogenide Nanomaterials for Conversion of Waste Heat to Electricity

“…Semiconductor nanostructures have greatly contributed to the growth of nanotechnology due to their high surface to volume ratio and tunable band gap. 34 This attractive class of materials has been used in many functional nanodevices including sensors, 35,36 transistors, 37 solar cells, 38 electrocatalysts, 39 photocatalysts, 40,41 adsorbents, 42,43 and nanogenerators. 44 The working of thermoelectric devices is based on three effects, namely, the Seebeck effect, 45 Peltier effect, 46 and Thomson effect.…”
