Abstract
The pursuit of RuO2 as an alternative acidic oxygen evolution reaction electrocatalyst to IrO2 holds great promise, yet simultaneously achieving highly active and stable RuO2 remains an urgent challenge, as conventional strategies often boost one property at the expense of the other. Here, we successfully construct Ta and B co-doped nanoporous RuO2 with Ru-O-Ta frameworks and Ru-O-B active sites to overcome the activity-stability trade-off. The Ru-O-Ta frameworks stabilize the Ru sites by mediating bridging oxygen and preferentially replenishing oxygen vacancies, thereby facilitating the oxygen evolution reaction through the adsorbate evolution mechanism. Concurrently, the Ru-O-Ta/B sites not only switch the…
