Abstract：

Hierarchical　porous　carbons　equipped　with　heteroatoms　and　diffusion　pores　have　a　wide　application　prospect　in　adsorption.　Herein,　we　report　N-autodoped　porous　carbons　(PTPACs),　which　were　derived　from　rigid　N-rich　conjugated　microporous　poly(aniline)s　(CMPAs)　and　show　their　all-around　applicability　in　heavy　metal　adsorption.　Their　molecular　structure　could　be　delicately　tuned　from　3D　organic　networks　to　graphitic　carbons　through　simply　adjusting　the　pyrolysis　temperature,　affording　unique　hybrid　features　of　hierarchical　micro-meso-macroporosity　and　amount-tunable　nitrogen　defects,　as　validated　by　the　enhanced　CO2adsorption　capacities　reaching　5.0　mmol　g-1,　a　230%　increase　compared　to　the　precursor　(2.15　mmol　g-1).　They　therefore　show　promising　a　Langmuir　adsorption　capacity　of　434.8　mg　g-1toward　mercury　ions,　which　could　be　rapidly　achieved　within　a　short　20　min.　Based　on　the　comprehensive　experimental,　characterization,　and　DFT　calculation　studies,　we　rationally　reveal　these　impressive　adsorptions　arise　from　the　hybrid　function　of　chemisorption　contributed　by　populated　nitrogen　defects　and　physical　adsorption　achieved　by　synergistic　functions　in　the　diffusion　and　storage　pores.　Outcomes　mark　the　high　merits　of　PTPACs　in　addressing　recent　global　challenges　in　environmental　engineering.　©　2022　Authors.　All　rights　reserved.
