Abstract
The biomass-based porous carbon produced by the conventional two-step method (carbonization followed by chemical activation) has a high production cost and an undeveloped mesopore/macropore structure. In this study, lignin was successfully converted into porous carbon (LPC) in one step by microwave heating combined with the use of humidified nitrogen. The obtained LPC had abundant micropores (0.70 cm?3
