Probing the Local Structure of Layered Double Hydroxide Electrocatalysts

imageNiFe-based hydroxide and oxyhydroxide electrocatalysts are among the best reported electrocatalysts for the oxygen evolution reaction. The fundamental role of Fe in this catalyst remains controversial. The Skrabalak group is using their expertise in solid-state synthesis to prepare these materials and studying how the local structure influences their properties for electrocatalysis. This work involves neutron diffraction measurements with collaborators at Oak Ridge National Laboratory.

In addition to these studies of layered double hydroxide materials, we are also applying synchrotron scattering methods to study the local structure of oxynitride photocatalysts and the ordering processes associated in the conversion of random alloys to intermetallics.

Funding provided by NSF-DMR (2016-2019) for "Spray Synthesis of Shape-Defined Nanocrystals".

Prospective Graduate Students

We seek 1-3 graduate students per year. All prospective students must apply directly to the program (link). Upon arrival at IU, students rotate in research groups and advisors are finalized then. Given the number of emails received, individual inquiries will likely go unanswered but you are encouraged to learn more through our website.

Undergraduate Research

Research opportunities available for undergraduates! Inquire via email. Include your resume, list of science courses completed, and gpa. Also, check out our Science Ambassadors' Program.
