A 3D/OD cobalt-embedded nitrogen-doped porous carbon/supramolecular porphyrin magnetic-separation photocatalyst with highly efficient pollutant degradation and water oxidation performance
文献摘要:
A 3D/0D cobalt-embedded nitrogen-doped porous carbon nanocubes(Co-N-C)/supramolecular tetra(4-carboxylphenyl)porphyrin nanocrystals(SA-TCPP)photocatalyst was successfully self-assembled via π-πinteraction,hydrogen bonding,and chemical bonding.Co-N-C/SA-TCPP heterostructure exhibited satis-factory visible photocatalytic oxidation performance on pollutant degradation and water evolution.The degradation rates of Co-N-C/ST(30%)composite towards 2,4-dichlorophenol,ofloxacin,and ethylene were 10.9,7.2,and 2.1 times faster than SA-TCPP,respectively.The oxygen evolution efficiency was 1.9 times higher than SA-TCPP.The remarkably improved oxidation activities of Co-N-C/SA-TCPP were mainly as-cribed to the following reasons:(1)Co-N-C could enhance the light absorption ability of SA-TCPP to produce more photoinduced carriers.(2)The well-developed porosity of Co-N-C could optimize the dis-persibility of SA-TCPP to provide more reactive sites and charge separation channels.(3)The π-π in-teraction between SA-TCPP and Co-N-C was beneficial to interlayer charge mobility,while the embed-ded cobalt nanoparticles(Co NPs)and N-doped carbon matrix could serve as electron traps to acceler-ate interfacial electron transfer.Additionally,the ferromagnetic Co NPs endowed Co-N-C/SA-TCPP with magnetic-separation function to promote recyclability in practical application.
