Abstract
A systematic study on the impact of the treatment temperature of IrOx supported onto doped-tin oxide (1 at% Ta–SnO2 and 10 at% Sb–SnO2) fibres led to electrocatalysts with high oxygen evolution reaction activity and resistance to degradation. The electrolytic performance was comparable to that of unsupported commercial IrO2 with seven times higher loading.
