Synergistic effect of cubic C3N4/ZnO/C hybrid composite for selective detection of sulfur dioxide
With the development of industrial society,the emission of SO2 gas increases sharply.Because of the harm of SO2 to the environment and human health,it is crucial to detect and capture SO2,especially to develop gas sensing mate-rials with good selectivity and durability to SO2.In this work,we prepared a C3N4/ZnO/C hybrid,MFM@IRMOF-3-T,for SO2 monitoring by annealing a composite of melamine-formaldehyde resin microsphere(MFM)and isoreticular metal-organic frameworks(IRMOF)-3.Com-pared with the annealed IRMOF-3 which has no response to SO2,MFM@IRMOF-3-T shows high selectivity,sta-bility and repeatability at 250℃.The efficient SO2 sensing performance could be attributed to the introduction of melamine-formaldehyde resin microspheres,the conver-sion of MFM to C3N4 and the bonding of nitrogen in MFM and zinc in IRMOF-3,which affect the direction of elec-tron transfer,improve the conductivity and reduce the resistance.This gas sensing material promotes the potential application of MOF-based derivant in the field of SO2 monitoring.
