Microstructure analysis of NiO nanocrystals and enhanced photocatalytic activities of NiO-CdS nanocomposites

Preparing Ti3C2-modified ZnFe2O4 photocatalytic materials and evaluating their performance in degrading tetracycline in water

“…Notably, some variations in the peak shape (widening) and positions (6.58°, 18.1°, 35.2°, 62.1°) are slightly shifted in the direction of the decreasing diffraction angle; such phenomena are related to the grain size, lattice distortion and residual stresses (microscopic and macroscopic). [25][26][27] This is because of the influence of different ion/composition changes on the crystalline phase. Ions with larger radii replace those with smaller radii in the structure, resulting in an increase in the lattice spacing, causing the peak shape and position to accordingly change.…”

In situ fabrication of a NiO nanoparticles/single-layered MXene nanosheet Schottky heterojunction toward sensing xylene and formaldehyde

“…18 Currently, according to literature reports, researchers have improved the response value and recovery speed of sensors by constructing heterostructures, 19 metal ion doping, 20 regulating the micromorphology 16 and light irradiation. 21 Combining MOSs with 2D nanomaterials is a new strategy to improve the gas sensitivity performance of sensors. [22][23][24] Twodimensional transition metal carbides, carbonitrides and nitrides (MXenes) have aroused scientic research enthusiasm due to their excellent electrical optical properties and unique sheet morphology.…”
