National Tsing Hua University develops nanoantenna to boost efficiency of generating clean hydrogen energy
The research team led by Prof. YEN Da-Jen of the Department of Materials Science and Engineering of Taiwan’s National Tsing Hua University breaks through the low-efficiency limitation of water splitting by using a plasmonic nano-antenna combined with bilayer molybdenum disulfide (MoS2) to enhance the efficiency of hydrogen production by nearly 30 times. The fruitful research findings of the team were published in the top journal Advanced Energy Materials and featured on the cover thereof.
According to Prof. Yen, there are two key factors of elevating the efficiency of hydrogen evolution. One of the two key factors is that nanoantenna will produce a super strong plasmon with a quadrupole reasonance after being optimized, and the other is that large surface-area of molybdenum disulfide makes the aforesaid method more commercially viable. The research findings will be applied for commercial production and further for green energy industry. (December 2018)
