Exploiting clean energy is essential for sustainable development and sunlight-driven photocatalytic water splitting represents one of the most promising approaches toward this goal. Metal-organic frameworks (MOFs) are competent photocatalysts owing to their tailorable functionality, well-defined structure, high porosity. Yet, introduction unambiguous metal-centered active site into MOFs still challenging since framework motifs capable anchoring metal ions firmly lacking. Herein, assembly...
Hot carriers (HCs) and thermal effects, stemming from plasmon decays, are crucial for most plasmonic applications. However, quantifying these two effects remains extremely challenging due to the experimental difficulty in accurately measuring temperature at reaction sites. Herein, we provide a novel strategy disentangle HCs photothermal based on different traits of heat dissipation (long range) transport (short range), quantitatively uncover dominant potential-dependent role effect by...
Ammonia, with high energy density and easy transportation, holds significant potential to become an integral part of future systems. Among tremendous strategies, electrocatalytic ammonia production is no doubt efficient eco-friendly method. One particularly intriguing class electrocatalysts for reducing nitrate transition metal oxides, which have been heavily researched. However, how these catalysts' oxygen vacancy (VO) affects their performance remains elusive. To address this, taking...
