▎ 摘　　要

NOVELTY - Preparation of nitrous oxide adsorbent comprises co-dissolving graphene oxide, magnesium compound and reducing agent in ethanol, reacting with ethylene glycol or tetrahydrofuran solution to obtain first intermediate product, filtering, adding filtrate with binder, extrusion molding, drying, soaking to group VI element solution as soaking agent, taking out, drying, and activating under carbon dioxide atmosphere. The mass ratio of graphene oxide and magnesium compound is 95-83:4-16. The mass ratio of graphene oxide and binder is 1-20:1-80. USE - The method is for preparation of nitrous oxide adsorbent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for regenerating nitrous oxide adsorbent comprising heating saturated nitrous oxide adsorbent at 200-450 degrees C for 5-8 times under nitrogen atmosphere.
