With the rise of living standards, non-biodegradable waste, especially waste plastics, has caused serious environmental problems. Herein, we prepare nitrogen doped porous carbon nanosheets (N-PCNs) using magnesium hydroxide [Mg(OH)2] sheets, which are modified by Zn and Co bimetallic zeolitic imidazolate framework nanoparticles as templates and polystyrene (PS) as a carbon...
