Abstract
Here, Eu-doped BiOBr photocatalysts were prepared by a one-step hydrothermal method using ethylene glycol as solvent and hexadecyl trimethyl ammonium bromide (CTAB) as Br source. The photocatalytic CO2 reduction performance of the samples under xenon lamp illumination was examined. The results indicate that Eu doped BiOBr exhibits a higher activity of photocatalytic CO2 reduction to CO/CH4 compared to the reference BiOBr. Moreover, The Eu doped BiOBr sample showed a remarkable stability in cycling experiments. This work provides a useful reference for optimizing design of 3D flower BiOBr photocatalyst to improve photocatalytic CO2 reduction efficiency.
本文以乙二醇为溶剂，十六烷基三甲基溴化铵（CTAB）为溴源，通过一步水热法制备了掺 Eu 的 BiOBr 光催化剂。考察了样品在氙灯照射下光催化还原 CO2 的性能。结果表明，与参考 BiOBr 相比，掺杂 Eu 的 BiOBr 具有更高的光催化 CO2 还原 CO/CH4 的活性。 此外，掺杂 Eu 的 BiOBr 样品在循环实验中表现出显著的稳定性。这项工作为优化三维花 BiOBr 光催化剂的设计以提高光催化还原 CO2 的效率提供了有益的参考。
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
