Carbon‑paper‑supported Fe‑doped WO3 catalysts engineered as a high‑performance bifunctional electrode for alkaline water splitting

Tungsten trioxide (WO 3 ) is an earth‑abundant and chemically robust semiconductor predominantly explored as a photoanode. A key limitation in earlier WO 3 studies is the reliance on fluorine‑doped tin oxide (FTO) substrates, whose flat 2D geometry, moderate conductivity, and sus...
