Crystalline IrO2-decorated TiO2 nanofiber scaffolds for robust and sustainable solar water oxidation†
Abstract
Crystalline IrO2 nanoparticles immobilized on TiO2 nanofiber scaffolds as robust and sustainable oxygen evolving catalysts showed a high turnover number (TON: 322) and excellent recyclability (90% O2 evolving after 10 cycles). The effects of the decoration position, crystallite size, loading amount of IrO2, and TiO2 scaffolds were investigated.
