Abstract

An inexpensive graphitic carbon nitrite (g-C3N4) photocatalyst was hybridized with selenium oxide (SeO2) photocatalyst by a monolayer-dispersed technique. After hybridization of g-C3N4 with SeO2, the NADH/NADPH regeneration efficiency of SeO2 photocatalyst was enhanced under solar light illumination was observed. The photocatalytic activity of SeO2/g-C3N4 photocatalyst under solar light illumination was enhanced by 3-fold higher than g-C3N4 photocatalyst, the solar light photocatalytic activity was produced and the photo-decomposition of SeO2 photocatalyst was completely stifled after hybridized SeO2 photocatalyst by g-C3N4 photocatalyst. The improvement in performance and photo-decomposition inhibition under solar light illumination was persuaded by efficiency separation of photo-persuaded holes from SeO2 to the valence bond (V.B.)/highest occupied molecular orbital (HOMO) of g-C3N4 under solar light illumination, the electron jumped from the V.B. to the conduction band (C.B.)/lowest unoccupied molecular orbital (LUMO) of g-C3N4 could directly insert into the C.B. of SeO2 photocatalyst, synthesized SeO2/g-C3N4 photocatalyst is highly active for NADH/NADPH regeneration under solar light.

合成高效氧化硒杂化g-C3N4光催化剂促进NADH/NADPH再生

采用单层分散技术将一种廉价的石墨亚硝酸碳(g-C3N4)光催化剂与氧化硒(SeO2)光催化剂杂化。g-C3N4与SeO2杂交后，在太阳光照下，SeO2光催化剂的NADH/NADPH再生效率提高。SeO2/g-C3N4光催化剂在太阳光照下的光催化活性比g-C3N4光催化剂提高了3倍，SeO2光催化剂与g-C3N4光催化剂杂交后产生了太阳光催化活性，完全抑制了SeO2光催化剂的光分解。在太阳光照下，SeO2的光诱导空穴与g-C3N4的价键(v.b)/最高已占据分子轨道(HOMO)有效分离，从v.b跃迁到g-C3N4的导带(c.b)/最低未占据分子轨道(LUMO)的电子可以直接插入到SeO2光催化剂的c.b上。合成的SeO2/g-C3N4光催化剂在太阳光下对NADH/NADPH再生具有高活性。

期刊介绍： Main Group Chemistry is intended to be a primary resource for all chemistry, engineering, biological, and materials researchers in both academia and in industry with an interest in the elements from the groups 1, 2, 12–18, lanthanides and actinides. The journal is committed to maintaining a high standard for its publications. This will be ensured by a rigorous peer-review process with most articles being reviewed by at least one editorial board member. Additionally, all manuscripts will be proofread and corrected by a dedicated copy editor located at the University of Kentucky.
