Hierarchical rh-In2O3 crystals derived from InOOH counterparts and their sensitivity to ammonia gas†
Abstract
Constructing novel materials with a hierarchical structure has become an increasingly hot research topic, because the hierarchical structures have wide potential applications in the fields of bionics, electronics, photocatalysis, solar cells, and lithium ion batteries. In this paper, we report on the fabrication of rhombohedral corundum-type indium oxide (rh-In2O3) hierarchical rod-aggregates by
