日益严重的环境和能源危机促使研究人员寻求新的解决方案，包括大规模光催化环境修复和利用光催化材料生产太阳能氢气。为了实现这一目标，科学家们开发了许多具有高效率和稳定性的光催化剂。然而，光催化系统在实际条件下的大规模应用仍然受到限制。这些限制出现在每一个步骤，包括大规模合成和沉积的光催化剂颗粒上的固体支持，并开发一个最佳的设计与高质量传递和有效的光子吸收。本文的目的是详细描述在扩大光催化系统用于大规模水和空气净化以及太阳能制氢方面遇到的主要挑战和潜在解决方案。此外，基于对当前试点发展的回顾，我们得出结论，并对影响性能的主要操作参数进行比较，并提出未来研究的策略。
The growing environmental and energy crises have prompted researchers to seek new solutions, including large-scale photocatalytic environmental remediation and the production of solar hydrogen using photocatalytic materials. To achieve this goal, scientists have developed numerous photocatalysts with high efficiency and stability. However, the large-scale application of photocatalytic systems under real-world conditions is still limited. These limitations arise at every step, including the large-scale synthesis and deposition of photocatalyst particles on a solid support, and the development of an optimal design with high mass transfer and efficient photon absorption. The purpose of this article is to provide a detailed description of the primary challenges and potential solutions encountered in scaling up photocatalytic systems for use in large-scale water and air purification and solar hydrogen production. Additionally, based on a review of current pilot developments, we draw conclusions and make comparisons regarding the main operating parameters that affect performance, as well as propose strategies for future research.
