Abstract: A method for producing mesoporous magnesium hydroxide nanoplates involving solvothermal treatment of a solution of a magnesium salt, a base, a glycol, and water is disclosed. The method does not use a surfactant or template in the solvothermal treatment. The method yields mesoporous nanoparticles of magnesium hydroxide having a plate-like morphology with a diameter of 20 nm to 100 nm, a mean pore diameter of 2 to 10 nm, a surface area of 50 to 70 m2/g, and a type-III nitrogen adsorption-desorption BET isotherm with a H3 hysteresis loop. An antibacterial composition containing the mesoporous magnesium hydroxide nanoplates is also disclosed. A method for reducing nitroaromatic compounds with a reducing agent and the mesoporous magnesium hydroxide nanoplates as a catalyst is also disclosed.

Abstract: A method for using a nanocomposite of tin cobalt oxide nanocubes and graphene oxide to photo-catalytically degrade a portion of an organic contaminant in a solution. The nanocubes have an average side length in a range of 400 nm-1.5 μm and a carbon to tin molar ratio in a range of 10:1-25:1. The nanocomposite may also be used for enhancing the efficiency of a liquid fuel.
