Microscale flower-like magnesium oxide for highly efficient photocatalytic degradation of organic dyes in aqueous solution
Flower-like MgO microparticles with excellent photocatalytic performance in degradation of various organic dyes ( e.g. , methylene blue, Congo red, thymol blue, bromothymol blue, eriochrome black T, and their mixture) were synthesized by a facile precipitation method via the reaction between Mg 2+ a...

description | Flower-like MgO microparticles with excellent photocatalytic performance in degradation of various organic dyes (
e.g.

at 70 °C. The reaction time was found to be crucial in determining the final morphology of flower-like MgO. After studying the particles from time-dependent experiments, scanning electron microscope observation, Fourier transform infrared spectra and thermogravimetric analyses demonstrated that the formation of flower-like particles involved a complex process, in which agglomerates or rod-like particles with a formula of
