#ESS2211: Sonochemical synthesis of catalysts for water electrolysis

Supervisor: Henrik Erring Hansen

---

Goals and tasks: The aim of this summer project is to synthesize inexpensive catalysts for water electrolysis by a novel ultrasound technique called sonochemistry. The student will perform the ultrasound synthesis, and analyze the resulting nanoparticles using UV-Vis spectroscopy and electrochemical techniques. As we will investigate nanoparticles, it is required that the student is familiar with nanotechnology and characterization of nanomaterials. Previous experience with laboratory work is also needed. - Synthesize nickel nanoparticles using ultrasound - Characterize nanoparticles using physical and electrochemical techniques

Desired skills and characteristics:

• The student is structured, disciplined and organized in their work.
• The student has knowledge about nanomaterial synthesis.
• The student is interested in nano science.
• Experience with NTNU Nanolab is preferred.
