Halloysite derived 1D mesoporous tubular g-C3N4: Synergy of template effect and associated carbon for boosting photocatalytic performance toward tetracycline removal

Halloysite, a natural clay mineral, has the advantages of hollow tubular morphology and abundant reserves. In this work, 1D mesoporous tubular g-C3N4 (TCN) was facilely synthesized through a calcination-leaching method using halloysite as a hard template for the first time. The synthesized 1D mesoporous tubular g-C3N4 could efficiently degrade tetracycline (TC) under visible light irradiation, and the highest degradation efficiency of TCN was...
