N-TiO2/MoS2/N-TiO2　(NT/MS/NT/ACFF)　photocatalyst　supported　by　activated　carbon　fiber　felt　(ACFF)　was　prepared　by　ultrasound　assisted　hydrothermal　method,　and　used　as　the　carrier　of　laccase.　The　NT/MS/NT/ACFF　immobilized　laccase　was　then　obtained　by　covalent　bonding　method.　The　morphology　and　microstructure　of　the　catalyst　were　characterized　by　means　of　SEM,　XRD,　BET,　Raman,　UV-vis　DRS　and　FTIR.　The　effects　of　different　systems　on　the　degradation　of　bisphenol　A　(BPA).　The　reaction　kinetics,　mineralization　rate　and　reusability　of　NT/MS/NT/ACFF　immobilized　laccase　were　studied.　The　results　showed　that　compared　with　other　systems,　NT/MS/NT/ACFF　immobilized　laccase　in　visible　light　had　the　best　degradation　rate　of　BPA　(82.5%),　the　apparent　rate　constant　kobs　was　0.00764　min-1,　and　the　mineralization　rate　was　up　to　64.5%.　NT/MS/NT/ACFF　immobilized　laccase　has　good　photocatalysis　performance,　enzyme　catalytic　activity　and　stability,　and　the　degradation　rate　of　BPA　can　still　reach　69.4%　after　4　cycles.　Through　GC-MS　analysis,　we　concluded　that　the　catalytic　degradation　of　BPA　by　NT/MS/NT/ACFF　immobilized　laccase　includes　steps　of　fracture　recombination,　oxidative　decomposition　and　ring-opening　reactions.　©　2025　Chemical　Industry　Press　Co.,　Ltd..　All　rights　reserved.
