摘要：

过氧化氢(H2O2)是100种最重要的化学品之一，广泛应用于漂白、消毒和合成化学等行业。最近，它被用作直接燃料电池的燃料。当前的H2O2生产依赖于苛刻的蒽醌氧化法。从环境、可持续性和经济角度来看，光催化H2O2生产是一种更有利的替代方法。该过程需要水和分子氧作为输入，并以阳光为唯一能源。尽管有这些优点，该技术的实际应用仍然具有挑战性。最常见的瓶颈是光催化剂的不足、上坡热力学、缓慢的过程动力学以及竞争性反应和逆向反应。本文讨论了这些局限性，并重点提出了提高效率和选择性的建议观点，旨在为大规模H2O2光生产铺平道路。

Abstract:

Hydrogen peroxide (H2O2) is one of the 100 most important chemicals used extensively in bleaching, disinfection, and synthetic chemistry industries. It is currently used as a fuel in direct fuel cells. The current H2O2 production relies on the harsh anthraquinone oxidation approach. Photocatalytic H2O2 production is a more favorable alternative from environmental, sustainability, and economic viewpoints. The process requires water and molecular oxygen as inputs and sunlight as the sole power source. Despite these merits, the practical application of this technology remains challenging. The most common bottlenecks are the photocatalyst's inadequacy, uphill thermodynamics, sluggish process kinetics, and competitive and backward reactions. This paper discusses these limitations and highlights the proposed perspectives to improve the efficiency and selectivity, aiming to pave the way toward large-scale H2O2 photogeneration.
