Abstract

Herein, we demonstrate the synthesis of a Bi2MoO6 nanorod array followed by the deposition of a BiVO4 absorber layer. This heterojunction yielded a photocurrent density of 250 μA cm−2 at 0.8 VSCE, which is 21 times that produced by a planar Bi2MoO6 array under the same conditions. Moreover, in situ X-ray photoelectron spectroscopy clearly confirmed the improvement of the electron transport and charge separation afforded by the heterostructure, features that efficiently enhanced the photoelectrochemical properties of the array.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
