Application of 2D Polyoxometalate Clusterphene in a High-Performance Photoelectrochemical Photodetector

Exploration of novel two-dimensional (2D) nanomaterials with desired properties using a controlled approach remains one of the major challenges ahead. Clusterphene, the newly emerged 2D formation of self-assembled clusters, exhibits a comparable structure to graphene with intriguing physicochemical features, which are applied in several scientific disciplines. Herein, it is demonstrated that polyoxometalate clusterphene (POMCene) is a promising 2D nanomaterial for photoelectrochemical (PEC) photodetection. The photodetection performance of POMCene can be subtly tuned by adjusting external conditions like bias voltage, electrolyte, and incident wavelength. A photocurrent of 1.88 & mu;A cm(-2), a responsivity of 2.26 & mu;A W-1, a detectivity of 5.65 x 10(9) Jones, and a fast response speed of 0.02 s along with good long-term stability can be achieved. It is believed that this research can pave a new direction for the future development of 2D POMCene in high-performance optoelectronic devices.
