Photocatalytic and electrochemical activity of magnesium oxide nanoballs synthesized via a hydrothermal route

Currently, there is growing concern about minimizing the environmental impacts caused by the generation of waste on water, soil, air pollution, and contamination of the environment in general. Magnesium oxide (MgO) nanoballs (NBs) were synthesized by the hydrothermal method followed by a calcination...
