Description
Summary:One-dimensional nanotube heterostructures with IrO -stabilized La IrO is obtained by an electrospinning approach. The La IrO /IrO catalyst exhibits superior catalytic activity and strong stability for the oxygen evolution reaction. The synergistic cooperation between the two types of Ir as the active sites in La IrO /IrO is demonstrated by Raman spectrum and DFT calculation.
