Abstract

En 中文

• Proposed a sustainable K2C2O4 activation protocol for biomass-derived carbons. • Tailored microporosity and N-doping to enhance CO2 affinity. • Achieved a high CO2 capacity (6.32 mmol g−1) with excellent selectivity and stability. • Provided mechanistic insights into the physisorption-driven CO2 adsorption process. • Converted bamboo shoot shell waste into a functional carbon material.
