Monolithic electrodes for oxygen evolution reaction (OER) have been successfully synthesized by hydrothermal method. Prolonging the hydrothermal duration and subsequent annealing treatment can increase the OER activities and stabilities of the samples. The IrO2/Ti-60h@400 shows excellent performance, which requires an overpotential of 391 mV at 100 mA cm-2, and could keep good activity at 200 mA cm-2 for 40 hours in acid electrolyte.

Few-layer exfoliated black phosphorus (Ex-BP) has attracted tremendous attention owing to its promising applications, including in electrocatalysis. However, it remains a challenge to directly use few-layer Ex-BP as oxygen-involved electrocatalyst because it is quite difficult to restrain structural degradation caused by spontaneous oxidation and keep it stable. Here, a robust carbon-stabilization strategy has been implemented to prepare carbon-coated Ex-BP/N-doped graphene nanosheet (Ex-BP/NGS@C) nanostructures at room temperature, which exhibit superior oxygen evolution reaction (OER) activity under alkaline conditions. Specifically, the as-synthesized Ex-BP/NGS@C hybrid presents a low overpotential of 257 mV at a current density of 10 mA cm−2 with a small Tafel slope of 52 mV dec−1 and shows high durability after long-term testing.
