Photoelectrocatalytic interface of boron-doped diamond: Modification, functionalization and environmental applications

Boron-doped diamond materials display excellent electrochemical properties, including large potential windows, low background currents, the ability to withstand extreme potentials, and a strong tendency to resist contamination. These materials have been well-studied in the field of electrochemistry by a variety of methods and advanced characterization techniques. This review highlights recent progress and achievements of boron-doped diamond in photoelectrochemical applications. After surface modification of boron-doped diamond (e.g. with metals, metal oxides, molecular catalysts, enzymes, etc.), boron-doped diamond has demonstrated excellent electrochemical and photoelectrochemical properties. Applications in the fields of photoelectrocatalysis, environmental pollutants degradation, energy conversion and (photo)electroanalysis are discussed. Moreover, the challenges and future research directions of boron-doped diamond photoelectrochemistry are discussed and outlined. This review would provide valuable theoretical guidance for boron-doped diamond photoelectrochemistry. (C) 2020 Elsevier Ltd. All rights reserved.
