文摘

A nanoporous ultrathin film (NPUF) electrode is constructed for water electrolysis. The NPUF electrode is a composite ultrathin film of nanoporous gold/IrO2. The NPUF electrode is prepared from a facile thermal annealing method. The NUTF electrode is featured in its ultrahigh electrocatalyst utilization. The NUTF electrode presents a much improved single cell performance.
