The 黑料天堂鈥檚 Dr. Arjun Dahal, an assistant professor in the Department of Physics, has been awarded a $300,893 grant by the National Science Foundation for his research on developing clean energy through heterostructure photocatalysts.

鈥淪cientific breakthroughs in developing innovative and green energy technologies can move economies away from fossil fuels,鈥 Dahal said. 鈥淎s hydrogen is regarded as a promising 鈥榞reen fuel,鈥 its production from the photocatalysis process by splitting water utilizing sunlight and photocatalyst materials is a promising method of generating clean energy. Designing innovative photocatalyst materials is the primary step to realize efficient hydrogen production.鈥

Dahal鈥檚 research aims to design efficient, low-cost and innovative photocatalyst materials. Through his research, Dahal is developing new ways to produce composite photocatalyst materials using two-dimensional metal oxides and 2D transitional metal dichalcogenides. 

鈥2D materials are those that extend in one plane like a piece of paper but are only a single atomic or molecular layer thick,鈥 Dahal said. 鈥淒ue to the synergistic effects of 2D zinc oxide and tungsten disulfide, the composite photocatalyst material can potentially be more efficient than conventional photocatalyst materials. After preparing the composite photocatalyst materials, we will investigate how its water-splitting efficiency can be further improved by investigating the roles of the various material鈥檚 properties.鈥 

Specifically, Dahal鈥檚 research group is studying fabrication methods to prepare composite materials incorporating 2D zinc oxide and 2D tungsten disulfide. By researching and finding different materials to split water to produce hydrogen, Dahal is creating sustainable clean energy with non harmful byproducts, a major win for the environment, while also training students in cutting-edge nanoscale science within the context of modern energy and environmental applications.

鈥淭he grant can support two undergraduate students throughout three years of project duration,鈥 Dahal said. 鈥淭he research project is strongly interdisciplinary, which teaches students physics and chemistry concepts.鈥

Dahal鈥檚 project, titled 鈥2D-WS2 Supported 2D-ZnO Nanoislands for Visible-Light-Driven Photocatalysis鈥 is funded through the National Science Foundation by the Chemical Catalysis Program in the Division of Chemistry and the Established Program to Stimulate Competitive Research.
