Abstract

Surface modification of oxygen evolution reaction (OER) cocatalysts is a promising approach to improve PEC water oxidation activity by accelerating the surface charge injection efficiency and catalytic reaction kinetics. However, the PEC performance is still restricted by inefficient charge transfer at the semiconductor/cocatalyst interface. In this study, ultrathin Ti3C2 nanosheets, serving as a highly efficient hole transport layer, were introduced into the Fe2O3/CoAl-layered double hydroxide (LDH) interface. The obtained Fe2O3–Ti3C2–CoAl photoanodes exhibited a significantly improved photocurrent density of 2.1 mA cm−2 at 1.23 V versus the reversible hydrogen electrode (RHE) under AM 1.5G illumination. In this system, the Ti3C2 nanolayer not only suppresses the interfacial recombination of photogenerated carriers but also facilitates efficient hole transfer from Fe2O3 to the OER cocatalyst, thus promoting the PEC performance. This study provides a new guideline for optimizing the charge transfer at the semiconductor/cocatalyst interface. [ABSTRACT FROM AUTHOR]

Abstract

•An interface bridging connection is constructed between the Zn0.76Co0.24S and Zn.Co-doped Ni3S2by in-situoxidative etching ni foam to provide ni source and followed sulfidation process to form sulfides.•The obtained ZCS@ZCNS-2 electrode exhibits the high capacitance of 6.4 f cm−2at 2 mA cm−1, with high-rate capability of 64% due to the structural features.•The possible structure and composition evolution mechanisms were presented.
