Regulating the Charge Migration in CuInSe₂ /N-Doped Carbon Nanorod Arrays via Interfacial Engineering for Boosting Photoelectrochemical Water Splitting.

ABSTRACT: Regulating the charge migration and separation in photoactive materials is a great challenge for developing photoelectrochemical (PEC) applications. Herein, inspired by capacitors, well-defined CuInSe₂ /N-doped carbon (CISe/N-C) nanorod arrays are synthesized by Cu/In-metal organic frame-derived method. Like the charge process of capacitor, the N-doped carbon can capture the photogenerated electron of CISe, and the strong interfacial coupling between CISe and N-doped carbon can modulate the charge migration and separation. The optimized the CISe/N-C photoanode achieves a maximum photocurrent of 4.28 mA cm^-2 at 1.23 V versus reversible hydrogen electrode (RHE) in neutral electrolyte solution under AM 1.5 G simulated sunlight (100 mW cm^-2 ), which is 8.4 time
