传统的光催化剂如TiO 2的一个主要缺点是它们只能在光照下工作，而且光必须是紫外线。作为该限制的解决方案，近年来已经开发了可见光驱动的能量存储光催化剂。然而，缺乏全阳光驱动（UV-可见光-NIR）且具有持久能量存储能力的能量存储光催化剂。在这里，我们报告了一种载铂和氢处理的WO 3，它在全太阳光谱（300- 1，000 nm）下表现出强吸收，并且具有超过300 h的超长储能时间，可以在黑暗中降解甲醛。 在这一新的材料体系中，氢处理的WO 3同时作为光捕获材料和能量存储材料，而Pt主要作为助催化剂发挥能量存储效应。该材料优异的全光谱吸收效应和长时间的储能能力使其成为一种潜在的太阳能储能材料和实用的光催化剂。
A major drawback of traditional photocatalysts like TiO2 is that they can only work under illumination, and the light has to be UV. As a solution for this limitation, visible-light-driven energy storage photocatalysts have been developed in recent years. However, energy storage photocatalysts that are full-sunlight-driven (UV-visible-NIR) and possess long-lasting energy storage ability are lacking. Here we report, a Pt-loaded and hydrogen-treated WO3 that exhibits a strong absorption at full-sunlight spectrum (300–1,000 nm), and with a super-long energy storage time of more than 300 h to have formaldehyde degraded in dark. In this new material system, the hydrogen treated WO3 functions as the light harvesting material and energy storage material simultaneously, while Pt mainly acts as the cocatalyst to have the energy storage effect displayed. The extraordinary full-spectrum absorption effect and long persistent energy storage ability make the material a potential solar-energy storage and an effective photocatalyst in practice.
