The hydrogen economy is a sunrise industry, which is considered the ultimate solution to power the future society. Photocatalytic overall water splitting is projected as a potential technology for H2 production. However, its performance is still far from meeting the criteria for large-scale production. This paper argues that photocatalytic overall water splitting is theoretically and practically hard to achieve. The limiting factors, including unfavorable thermodynamics, slow kinetics, dissolved oxygen, and rapid backward reaction, are discussed. This paper is expected to give readers a better understanding of the photocatalytic overall water splitting and analyze the associated challenges in every subtle aspect.

光催化整体水分解的挑战
氢经济是一个朝阳产业，被认为是为未来社会提供动力的终极解决方案。光催化整体水分解预计是一种潜在的 H 2生产技术。然而，其性能仍远未达到规模化生产的标准。本文认为光催化整体水分解在理论上和实践上都难以实现。讨论了限制因素，包括不利的热力学、缓慢的动力学、溶解氧和快速的反向反应。本文有望让读者更好地了解光催化整体水分解，并分析每个微妙方面的相关挑战。
