Scholarship / A renewable energy - essay for study plan KGSP, department of energy engineering [11]

@Holt
yes, i have done some research about synthesis ZnO as semiconductor for Dye sensitized solar cell.
Now, I stuck on expected outcome. So, I just add a little bit in my essay (in bold word).
do you thing this expected outcome enough ? or I need to add more ? please advice.

I am applying for this master's program in department of energy engineering at Kyungpook National University. In this master's program, I have plan to conduct research about developing photochemical cell water splitting as converter energy from chemical energy to form of fuel.

Scholarship / A renewable energy - essay for study plan KGSP, department of energy engineering [11]

I would like to applying Korean government scholarship, and I need to make study plan.
I never made one before, and this is my first essay. Please help me to correct the grammar and give your suggestion for my essay. Thank you very much.

hydrogen energy research



I am applying for this master's program in department of energy engineering at xxx university. I have learnt that xxx University has done many researches about developing solar cell and applying to many environmentally energy, such as produce solar hydrogen, electro analytic water treatment, and photo electrochemical cell. I have interesting in environmental preservation and developing a renewable energy to decrease exploitation of fossil fuel, so we can maintaining our environmental, including hydrogen production, carbon dioxide reduction, and the destruction of pollutants. I believe with this master's program can help me to pursue my dream to be a specialty in the field of energy and environmentally.

In this master's program, I have plan to conduct research about developing photochemical cell water splitting as converter energy from chemical energy to form of fuel. This idea comes along with my awareness about the effect in increasing of global warming. As we know hydrogen, the fuel with the highest energy capacity, has the potential to replace fossil fuels. There are so many factors that make photochemical water splitting can produce with high efficiency such as particle size of semiconductor, catalyst, and photosensitizer. This research will bring issue about which photo catalyst should be used to produce the higher activity.

My bachelor degree in Chemistry has prepared me with a strong grounding in analysis and chemical reaction. I have learned about Chemometry, Basic Chemistry I and II, Analytical Chemistry I and II, Physical Chemistry I, II, and III, Inorganic Synthesis, Chemical Spectroscopy, Chemical Thermodynamics, Environmental Chemistry, Advance Analytical Chemistry II, Electrochemistry, and Battery and Fuel Cell in my bachelor study. Then, I completed my bachelor degree with predicate very satisfactorily. I have prepare myself to perform well in my future study.

There are so many report about photochemical water splitting in which an attempt is made to create a photo catalyst with the highest activity. Based on literature, to create the best photo catalyst is to tune the band gap, to find the best band gap we need to know the properties of it. In this research, I will use ZnO modified as photo catalyst source. As we know, ZnO has widely band gap around 3.37 eV that can absorb in visible light. ZnO has three crystalline form, such as rock salt, cubical zinc blende, and hexagonal wurtzite. Each form has their own characterize. ZnO could split water into H2 and O2 stoichiometrically under visible light, after modification with another co - catalyst.

This research will be valuable in the future concerning about energy and environmentally. Hydrogen that generated from water and sunlight, a process on photochemical water splitting, can provide clean fuel with low cost and environmentally friendly conversion of solar cell. Furthermore, the combustion of hydrogen energy does not lead to the emission of carbon dioxide (CO2) which is especially notorious as a greenhouse gas causing the global heating on the earth.
