Titanate-based perovskites for photochemical and photoelectrochemical water splitting applications: A review

摘要

Recently, perovskites have been intensively studied for effective hydrogen production through photocatalytic water splitting reactions. The unique properties of perovskite materials are their tunable bandgap and high photocorrosion stability. Titanate-based perovskites are the most widely studied perovskites for activation under visible light and improvement in the hydrogen gas production rate by sunlight. Beneficial modifications were achieved through element doping, catalyst loading, heterojunction formation with other materials and surface modification. This review presents the progress over the last ten years in titanate perovskite modification and the increases achieved in the H2production rate.
