摘　　要：For environmental applications,it is crucial to rationally design and synthesize photocatalysts with positive exciton splitting and interfacial charge transfer.Here,a novel Agbridged dual Z-scheme Ag/g-C_(3)N_(4)/CoNi-LDH plasmonic heterojunction was successfully synthesized using a simple method,with the goal of overcoming the common drawbacks of traditional photocatalysts such as weak photoresponsivity,rapid combination of photogenerated carriers,and unstable structure.These materials were characterized by XRD,FT-IR,SEM,TEM UV-Vis/DRS,and XPS to verify the structure and stability of the heterostructure.The pristine LDH,g-C_(3)N_(4),and Ag/g-C_(3)N_(4)/CoNi-LDH composite were investigated as photocatalysts for water remediation,an environmentally motivated process.Specifically,the photocatalytic degradation of tetracycline was studied as a model reaction.The performance of the supports and composite catalyst were determined by evaluating both the degradation and adsorption phenomenon.The influence of several experimental parameters such as catalyst loading,pH,and tetracycline concentrationwere evaluated.The current study provides important data for water treatment and similar environmental protection applications.
