Phosphorus nitride nano-dots as a versatile and metal-free support for efficient photoelectrochemical water oxidation†
Abstract
Phosphorus nitride dots (PNDs) are employed as a metal-free and versatile support over a range of metal oxide-based photoanodes for efficient photoelectrochemical (PEC) water oxidation. PNDs have the ability to form various heterojunctions by virtue of their favorable band positions for enhanced charge separation leading to improved photocurrent densities.
