Facile temperature-controlled synthesis of hexagonal Zn2GeO4nanorods with different aspect ratios toward improved photocatalytic activity for overall water splitting and photoreduction of CO2

Abstract

Single-crystalline hexagonal prism Zn₂GeO₄nanorods with different aspect ratios have been prepared via a solution phase route, which exhibits improved photocatalytic activities in overall water splitting and photoreduction of CO₂ due to the low crystal defects, high specific surface area and beneficial microstructure on the catalyst's surface.
