Ultrafast Hole Preservation with Undercoordinated Tungsten for Efficient Solar-to-Chemical Conversion
Solar-to-chemical conversion is crucial, as it can form chemicals that are easy to store. Hydrogen peroxide (H2O2) represents a favorable chemical for energy storage and disinfection. Solar driven H2O2 photocatalysis is a promising method, as it could greatly reduce costs and provide on-demand production. The big challenge lies in achieving optimum production rate with reasonable materials cost. Herein, by precise control of synthetic conditions, tungsten (W)-based metal–organic-framework (MOF) with up to 28.64% undercoordinated W4/5+ is prepared. The H2O2 photoproduction rate up to 330,000 μmol g–1 h–1 L–1 is achieved, highest for non-noble metal-based catalysts. A multistage solar driven evaporation system further increases H2O2 concentration to 0.43 wt %, reaching application level for water treatment. Such an efficient production originates from ultrafast hole preservation, which enables a two-electron transfer reaction pathway for H2O2 production. Our work highlighted the potential of MOF-based photocatalyst for on-demand and large scale H2O2 production.

期刊介绍:
ACS Energy Letters is a monthly journal that publishes papers reporting new scientific advances in energy research. The journal focuses on topics that are of interest to scientists working in the fundamental and applied sciences. Rapid publication is a central criterion for acceptance, and the journal is known for its quick publication times, with an average of 4-6 weeks from submission to web publication in As Soon As Publishable format.
ACS Energy Letters is ranked as the number one journal in the Web of Science Electrochemistry category. It also ranks within the top 10 journals for Physical Chemistry, Energy & Fuels, and Nanoscience & Nanotechnology.
The journal offers several types of articles, including Letters, Energy Express, Perspectives, Reviews, Editorials, Viewpoints and Energy Focus. Additionally, authors have the option to submit videos that summarize or support the information presented in a Perspective or Review article, which can be highlighted on the journal's website. ACS Energy Letters is abstracted and indexed in Chemical Abstracts Service/SciFinder, EBSCO-summon, PubMed, Web of Science, Scopus and Portico.
