“EPFL Researchers Boost Solar Hydrogen Production by Tuning Platinum Surface Chemistry in O” — what this page in the network covers. Scientists at EPFL's LIMNO laboratory have discovered that varying halides can alter the surface chemistry of organic semiconductor nanoparticle photocatalysts, leading to significant gains in solar hydrogen production. The team found that halides such as chloride, bromide, and iodide modify the platinum co-catalyst's surface, affecting how well it drives the hydrogen evolution reaction. By carefully controlling these halide-induced changes, the researchers achieved a marked improvement in the efficiency of solar-to-hydrogen conversion.
This work matters because organic photocatalysts are cheaper and more sustainable than traditional inorganic materials, but they have historically suffered from low performance. The findings, published in a peer-reviewed journal, offer a new strategy to close that gap, potentially making green hydrogen more viable for large-scale clean energy storage.
