Graduate Training & Research

Graduate Training & Research

Students here take ownership of a real research question from day one — a CO₂-to-formate gas-diffusion electrode, a self-healing antimony-selenide absorber, a CO₂-capturing electrocatalytic membrane — and build the electrochemistry, thin-film growth, and microscopy skills to answer it. Several have co-authored papers before finishing their degree, and former members have gone on to postdoctoral positions and, in some cases, faculty roles.

A Collaborative Research Environment

A Collaborative Research Environment

Our 120 m² lab carries an idea from synthesis to working device under one roof: atomic-layer and thermal deposition, CO₂ electrolyzers, a multi-channel potentiostat bench, deep-level transient spectroscopy, and an FTIR spectrometer configured for in-situ electrochemistry — complemented by access to BGU’s IKI Center for XPS and electron microscopy.
