Clean energy and clean water are the two utmost challenges that mankind have to achieve to keep this planet a home for generations to come. Current energy sources that keep the world lit are actually darkening our world due to greenhouse gas emissions and so are the industrial processes do pollute the environment. However, energy and industries are vital to support human on earth. So, clean, renewable and affordable alternative energy and efficient water treatment processes are a necessity. Photocatalysis is a process that harnesses solar energy to address the both challenges: clean energy and clean water by assisting in waste water treatment. Titanium dioxide is proven as a potential candidate for photocatalysis; however, the high frequency of recombination of solar excited charge carriers is major drawback which reduces its efficiency. Magnesium oxide is an earth abundant material which is an insulator and is known to suppress the extent of recombination of charge carriers. In addition, it is also known to affect the photocatalytic activity by trapping charge carriers in its surface defects. In this study, we synthesized TiO<sub>2</sub>-MgO mixed oxide materials by microwave assisted hydrothermal synthesis method in a relatively short time without the use of any structure directing agents. The photocatalytic experiments toward hydrogen production by these mixed oxides is primarily depended on loading of titania whereas the activity for photocatalytic degradation favors small particle size and higher loading of magnesium oxide.
