摘要： 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.

摘要： A method for enhancing the efficiency of a liquid fuel is described. The method involves the addition of cobalt hydroxystannate nanoparticles to the liquid fuel to produce an enhanced liquid fuel. The cobalt hydroxystannate nanoparticles may be present at a concentration of 50-200 ppm, and may increase the calorific value of the fuel by a factor of 25-52 times.
