▎ 摘　　要

NOVELTY - Mesoporous zinc hydroxystannate-modified graphene oxide hybrid antimicrobial agent has pasticle size of 30-80 nm, where zinc hydroxystannate has pore size of 1-5 nm. The graphene oxide is present in antibacterial agent in ratio of 2.5-10 wt.%. USE - Mesoporous zinc hydroxystannate-modified graphene oxide hybrid antimicrobial agent. ADVANTAGE - The mesoporous zinc hydroxystannate-modified graphene oxide hybrid antimicrobial agent ensures strong adsorption capacity, enhanced bacteriostatic and sterilization ability, simple preparation method, milder reaction conditions, high yield, low production cost and large-scale industrial production. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing mesoporous zinc hydroxystannate-modified graphene oxide hybrid antimicrobial agent, which involves stirring zinc salts, tin salts and graphene oxide with reaction medium for 1-6 hours at 0-60 degrees C, where reaction mixture is filtered and dried to obtain product.
