• Description
The current global energy annual consumption is about ca. 15 TW which is projected to be ca. 28 TW by 2050.  The main contribution to this ever increasing of energy demand comes from fast economic growth and increasing of life level of emerging and developing countries. Current supply is mainly ensured by fossil energies whose combustion results in CO2 emission that causes serious climate and environmental issues. Toward a sustainable development and to limit our dependence on fossil energies, great global efforts have being mobilized to identify novel technologies to exploit sustainable energies.
Among renewable energies being available to the human being, solar energy is the most abundant. Solar energy reaches the earth surface during one hour is equivalent to our annual energy consumption at the world scale. Thus, exploiting solar energy represents a great opportunity to address to the globe energy demand. During last decades, important resources have been invested in the solar energy research area with engagement of world class research institutions in USA, Europe and Asia. However, to the best of our knowledge, research field of solar energy conversion is still young in Vietnam where competitive research laboratories working in this field are absent.
In this research proposal, entitled “Designing Viable PhotoElectroChemical Cells for Solar Hydrogen Production” (PECH2), we propose to work on catalysis and structuring of nanomaterials toward creation of technological devices that can convert solar energy into chemical energy stored within H2 molecules.
This research project is designed based on our recent progress on development of photoanode for solar water splitting  and photocathode for solar H2 production. Ultimate goal of this project is to select appropriate photoelectrodes for engineering a bias-free tandem PEC device. To achieve this goal, we propose to work both on light absorbing materials and on WOR and HER catalysts. We anticipate by improving catalytic activities of metal-oxide-based WOR catalysts and metal-sulfide-based HER catalysts, we can also designing a functional artificial leaf by incorporating the best dual catalysts within a solar cell, type triple junction Si solar cell or perovskite solar cell.
