Abstract:
Efficiently converting methane into valuable chemicals via photocatalysis under mild condition represents a sustainable route to energy storage and value-added manufacture. Despite continued interest in this area, the achievements have been overshadowed by the absence of standardized protocols for conducting photocatalytic methane oxidation experiments as well as evaluating the corresponding performance. In this review, we present a structured solution aimed at addressing these challenges. Firstly, we introduce the norms underlying reactor design and outline various configurations in the gas-solid and gas-solid-liquid reaction systems. This discussion helps choosing the suitable reactors for methane conversion experiments. Subsequently, we offer a comprehensive step-by-step protocol applicable to diverse methane-conversion reactions. Emphasizing meticulous verification and accurate quantification of the products, this protocol highlights the significance of mitigating contamination sources and selecting appropriate detection methods. Lastly, we propose the standardized performance metrics crucial for evaluating photocatalytic methane conversion. By defining these metrics, the community could obtain the consensus of assessing the performance across different studies. Moving forward, the future of photocatalytic methane conversion necessitates further refinement of stringent experimental standards and evaluation criteria. Moreover, development of scalable reactor is essential to facilitate the transition from laboratory proof-of-concept to potentially industrial production.
摘要:
在温和条件下通过光催化有效地将甲烷转化为有价值的化学品代表了能量储存和增值制造的可持续途径。尽管对这一领域有持续的兴趣,由于缺乏进行光催化甲烷氧化实验以及评估相应性能的标准化协议,这些成就被掩盖了。在这次审查中,我们提出了一个旨在应对这些挑战的结构化解决方案。首先,我们介绍了反应器设计的基本规范,并概述了气-固和气-固-液反应系统中的各种配置。该讨论有助于选择适合甲烷转化实验的反应器。随后,我们提供了一个全面的一步一步的协议适用于不同的甲烷转化反应。强调对产品的细致验证和准确量化,该方案强调了减少污染源和选择适当检测方法的重要性.最后,我们提出了对评估光催化甲烷转化率至关重要的标准化性能指标。通过定义这些指标,社区可以在评估不同研究的表现方面达成共识。往前走,光催化甲烷转化的未来需要进一步完善严格的实验标准和评价标准。此外,可扩展反应器的开发对于促进从实验室概念验证到潜在工业生产的过渡至关重要。
