So far, it remains demanding to fabricate transition metal doped-crosslinked polymer-inorganic films with controlled photoelectrochemical performance that were stable in the aggressive solutions. Here, we report a new strategy to preparing transition metal doped-crosslinked polymer-inorganic layers with improved photoelectrochemical activity by manipulating the types of metal ions (Fe(III) and Co(II)) in the presence of polyvinyl alcohol (PVA) and ethylenediaminetetraacetic acid (EDTA), as crosslinking agents, in the hydrogen film “PEM” (P: PVA; E:EDTA; M: Fe(III)/Co(III)). PEM is prepared by interfacial crosslinking and then complexing process via static chemical conversion (SCC) on the inorganic layer (IL) surface fabricated via plasma electrolysis (PE). The photoelectrochemical performance is improved significantly in the order of IL-PEFe, IL-PECo, and IL-PEFe*Co, which may be due to transition metal ions and crosslinked polymers.Graphical abstract
