摘　　要：Memory catalysis and conventional Fenton reactions are intended to counteract prevailing energy and environmental crises;however,poor performance and the need for UV irradiation question their sustain-ability.Herein,we demonstrate defect-engineered,dual Z-scheme MoS_(2)/WO_(3-x)/Ag_(2)S exhibiting enhanced photo-Fenton(PFR),night-Fenton(NFR),and photocatalytic activities(PR)against tetracycline(TC)and Rhodamine B(RhB).Defects enable the catalyst to store ample electrons just like metals,which play a vi-tal role by exciting H2 O2 during Fenton reactions.It removed 91.54%,76.43%,and 83.39%TC(40 mg L^(-1))in 100 min and registered degradation rate constants of 0.05379,0.02858,and 0.04133 min^(-1)against RhB(20 mg L^(-1))during PFR,NFR,and PR respectively.The total organic carbon(TOC)removal rates reached 58.56%and 60.88%during TC and RhB degradations in PFR,respectively.Solid and Liquid EPR analy-sis shows it can excite H_(2)O_(2)to carry Fenton reactions with and without light.It demonstrates wide pH adaptability and tremendous potential to simultaneously counter energy and environmental crises.
