摘要:

发展可持续的光催化技术,以实现生物质向高附加值化学品和清洁燃料的高效转化,是应对全球能源与环境危机有效途径。本研究通过原位生长法构建了一种新型一维/二维(1D/2D)In2O3/ZnIn2S4 S型异质结光催化剂。该设计巧妙结合棒状In2O3与片状ZnIn2S4,促进定向电荷传输并提供高密度活性位点。因此,优化后的In2O3/ZnIn2S4异质结在420 nm LED光照下对5-羟甲基糠醛(HMF)转化率达81.6%,且对2,5-二甲酰基呋喃(DFF)和2,5-呋喃二甲酸(FDCA)的选择性高达78.2%。同时,该异质结表现出257.69 μmol g−1 h−1的产氢(H2)速率。这些结果表明,S型异质结能有效实现空间电荷分离并提升光催化活性,为太阳能驱动的生物质增值与可持续产氢提供了可行策略。

Abstract:

Addressing the global energy and environmental crisis necessitates the development of sustainable photocatalytic technologies capable of efficiently converting biomass into high-value chemicals and clean fuels. In this study, we develop a novel one-dimensional/two-dimensional (1D/2D) In2O3/ZnIn2S4 S-scheme heterojunction photocatalyst through in situ growth process. This rationally designed architecture combines rod-like In2O3 with sheet-like ZnIn2S4 nanosheets, facilitating directional charge transport and providing a high density of active sites. Consequently, the optimized In2O3/ZnIn2S4 heterojunction achieved a 5-hydroxymethylfurfural (HMF) conversion rate of 81.6% with a high selectivity of 78.2% toward 2,5-diformylfuran (DFF) and 2,5-furandicarboxylic acid (FDCA). Furthermore, it exhibited a hydrogen (H2) evolution rate of 257.69 μmol g−1 h−1 under 420 nm LED irradiation. These results demonstrate the efficacy of S-scheme heterojunctions in enabling spatial charge separation and boosting photocatalytic activity, offering a promising strategy for solar-driven biomass valorization and sustainable H2 production.
