▎ 摘　　要

NOVELTY - Preparing one-step synthetic graphene-coated iron doped carbon core-shell material comprises (a) taking precursor containing 6-35 wt.% glucose and 4-12 wt.% ferric hydroxide colloid, thus molar ratio of glucose to ferric hydroxide colloid is 10-2:1, hydrothermally reacting at 160-240 degrees C for 4-18 hours and carrying out self-assembly to obtain black solid phase product and (b) separating black solid phase product obtained in step (a), washing, drying and calcining in oxygen-free atmosphere to obtain graphene-coated iron doped carbon core-shell material. USE - The method is useful for preparing one-step synthetic graphene-coated iron doped carbon core-shell. ADVANTAGE - The method utilizes low cost glucose as sole carbon source and ferric chloride as sole iron source to precisely adjust dosage of iron, carbon, hydrothermal time and hydrothermal temperature; has simple and fast process; and is environmentally friendly. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) iron doped carbon core-shell material prepared by above mentioned method comprising graphene shell and an inner iron core, where the inner iron core is zero-valent iron, iron tetroxide and iron sesquioxide; (2) use of iron doped carbon core-shell material in removing phenolic organic pollutants; and (3) catalytic degradation material of phenolic organic pollutants comprising persulfate and iron doped carbon core-shell material.
