One-pot synthesis of Cu-modified HNb3O8 nanobelts with enhanced photocatalytic hydrogen production

Abstract

Ultrathin nano-materials have aroused much attention because of enhanced photocatalytic activities. However, conventional exfoliation methods require a complex preparation procedure and the intercalated cationic organic compounds are difficult to remove. Here, HNb3O8 nanobelts were successfully prepared by a one-pot hydrothermal route by using POM precursors. With the aid of acetic acid, Cu ions were carried easily through one-pot synthesis, and enhanced the photocatalytic water splitting performance significantly (8 times higher than unmodified nanobelts). Based on the XPS results, Cu ions had mixed oxidation states of Cu+/Cu2+ and the ratio did not change after calcination at 350°C, indicating that a part of Cu+ ions were inserted between the layers. And the roles of Cu in promoting hydrogen evolution activities were attributed to the improvement of separation of photo-induced carriers and the photo-to-electron conversion efficiency, confirmed by the analysis of photocurrent response and photoluminescence.
