Abstract

Compared to traditional energy-intensive ammonia (NH₃) production methods, photocatalytic nitrogen (N₂) reduction offers significant energy savings. However, the complex kinetics and high reaction barriers have hindered its development. In this study, a novel Bi₂₄O₃₁Br₁₀/polyaniline (Bi₂₄O₃₁Br₁₀/PANI) composite photocatalyst was synthesized using a simple solvothermal and chemical oxidation polymerization method. Aniline was oxidized and deposited onto the surface of Bi₂₄O₃₁Br₁₀ nanosheets. The Bi₂₄O₃₁Br₁₀/PANI composite demonstrated better visible-light absorption, and more efficient transfer of photoexcited carriers than pure Bi₂₄O₃₁Br₁₀, resulting in superior photocatalytic N₂ fixation performance. The optimized Bi₂₄O₃₁Br₁₀/PANI composite attained an NH₃ production yield of 245.26 µmol g⁻¹ , approximately 7.0 times higher than pure Bi₂₄O₃₁Br₁₀. This study provides a new design of inorganic-polymer hybrid photocatalysts for efficient photocatalytic nitrogen fixation.

期刊介绍： Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis. The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
