Abstract

•	A biochar aerogel decorated with Ru/RuS₂ particles was synthesized successfully.
•	Plenty of defects at carbon were formed due to regulation of two kinds of biomass.
•	The sample required a low overpotential of 228 mV at 10 mA cm⁻² in 0.5 M H₂SO₄.
•	The unique 2D/3D microstructures in biochar aerogel enhanced mass transfer ability.
