Macroscopic Foam‐Like Holey Ultrathin g‐C3N4 Nanosheets for Drastic Improvement of Visible‐Light Photocatalytic Activity

Holey ultrathin g-C3N4 nanosheets (CNHS) with abundant micro-, meso-, and macropores are fabricated by thermal "etching" of bulk g-C3N4. The prepared CNHS possess a unique ultralight characteristic, high specific surface area, more catalytic active sites, and enhanced electron transport ability, leading to a much superior activity in hydrogen generation and photodegradation of pollutant.
