Abstract

A synthetic semiconductive p-type diamond electrode was photosensitized by the Ru(bpy)32+ molecule in an electrolyte solution. The photoexcited molecule injects a hole into the valence band. However, under a certain potential, charge recombination occurred through interband states; the hole on the top of the valence band recombined with the photoreduced Ru(bpy)31+. The mechanism of this charge recombination was studied by measuring the transient photopotential and the intrinsic sub-band gap photoresponse of the electrode.

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.
