Abstract

Developing a low-cost photocatalyst with efficient performance is significant for practical application of solar-to-fuel conversion. Here, we first adopt a facile method to synthesize Bi ₂ O ₂ CO ₃ -modified g-C ₃ N ₄ heterojunction via in situ thermal growth. Bi ₂ O ₂ CO ₃ nanoparticles on g-C ₃ N ₄ nanosheets play a vital role in improving the photocatalytic activity of splitting water for hydrogen production. The activity of Bi ₂ O ₂ CO ₃ /g-C ₃ N ₄ heterojunction during 5 h reaches 965 μmol·g ^-1 ·h ^-1 , which is much higher than that of pure g-C ₃ N ₄ (337 μmol·g ^-1 ·h ^-1 ) or other modified g-C ₃ N ₄ materials. The significantly enhanced photocatalytic activity is attributed to direct Z-scheme system construction, resulting in a superior charge carrier separation ability. Theoretical calculations further reveal the redistribution of charge carrier at interface between Bi ₂ O ₂ CO ₃ and g-C ₃ N ₄ . This work provides new direction to synthesize g-C ₃ N ₄ -based heterojunction with high photocatalytic performance for alleviating energy and environmental issues.
