One-step large-scale highly active g-C3N4 nanosheets for efficient sunlight-driven photocatalytic hydrogen production

The development of highly active, cost-effective, environmentally friendly and stable g-C3N4 based photocatalysts for H2 evolution is one of the most anticipated potential pathways for future hydrogen utilisation. In the present study, a facile gaseous bubble template approach was designed to prepare large-scale thin g-C3N4 nanosheets (g-C3N4 NSs) using melamine and ammonium sulphate as the bubble template. Through distinctive structural improvements for a large bandgap, excellent electron mobility, prolonged lifetime of the photogenerated charge carriers and a high specific surface area with highly accessible potential reaction sites, the as-synthesised g-C3N4 NSs demonstrated a high photocatalytic hydrogen evolution rate of 9871 ?mol h(-1) g(-1) and efficient photocatalytic degradation of Rhodamine B (RhB) and phenol under simulated solar light irradiation.
