摘要

•Crumpled carbon-nitride nanosheets were prepared via a facile stepwise pyrolytic strategy.•The morphology and optical–electronic properties of the crumpled PCN nanosheets was tuned by regulating the pyrolysis time.•Crumpled PCN nanosheets can provide numerous reactive sites for surface reactions.•Crumpled PCN nanosheets exhibit notable photocatalytic CO2-conversion activities.
