Jianwu Sun holds a permanent position as Universitetslektor at IFM, Linköping University. He received his Docent (Associate Professor) title in 2016. Prior to this, he worked as Senior Researcher in the world-leading industrial research center, IMEC, Belgium. He has more than ten-year academic and industrial research experience on semiconductor materials.
Now, his research group mainly focuses on exploring the semiconductor materials for solar-driven energy conversion, in particular, photocatalytic and photoelectrochemical (PEC) water splitting and reduction of CO2.
The solar-driven water splitting provides a promising way to produce hydrogen, which is regarded as a clean and renewable energy source. Moreover, the solar-driven conversion of CO2 and water into chemical fuels is also a very attractive approach to explore renewable energy by consuming and recycling the greenhouse gas CO2.
Now Jianwu Sun has been granted on the research of exploring cubic silicon carbide (3C-SiC) as a photoelectrode for the PEC water splitting and CO2 reduction. Compared to commonly studied photoelectrode materials, the 3C-SiC has outstanding properties such as suitable bandgap (2.36 eV) for efficient visible light absorption and proper energetics for water splitting without applying external bias.
