(https://creativecommons.org/licenses/by/3.0/) abstract: Water oxidation is a rate-determining step in solar driven H2 fuel synthesis and is technically challenging to promote. Despite decades of effort, only a few inorganic catalysts are effective and even fewer are effective under visible light. Recently, attention has been paid to synthetic semiconducting polymers, mainly on graphitic C3N4, with encouraging hydrogen evolution performance but lower activity for water oxidation. Here, a highly ordered covalent triazine-based framework, CTF-1 (C8N2H4), is synthesised by a very mild microwave-assisted polymerisation approach. It demonstrates extremely high activity for oxygen evolution under visible light irradiation, leading to an apparent quantum efficiency (AQE) of nearly 4% at 420 nm. Furthermore, the polymer can also efficiently evolve H2 from water. A high AQE of 6% at 420 nm for H2 production has also been achieved. The polymer holds great potential for overall water splitting. This exceptional performance is attributed to its well-defined and ordered structure, low carbonisation, and superior band positions. date: 2018-06-01 date_type: published publisher: ROYAL SOC CHEMISTRY official_url: http://dx.doi.org/10.1039/c7ee02981k oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green article_type_text: Article verified: verified_manual elements_id: 1565628 doi: 10.1039/c7ee02981k lyricists_name: Guo, Zheng Xiao lyricists_name: Lau, Chi lyricists_name: Ruan, Qiushi lyricists_name: Tang, Junwang lyricists_name: Xie, Jijia lyricists_id: ZXGUO56 lyricists_id: CLAUX77 lyricists_id: QRUAN67 lyricists_id: JTANG13 lyricists_id: JXIEX47 actors_name: Cuccu, Clara actors_id: CCCUC40 actors_role: owner full_text_status: public publication: Energy and Environmental Science volume: 11 number: 6 pagerange: 1617-1624 pages: 8 issn: 1754-5706 citation: Xie, J; Shevlin, SA; Ruan, Q; Moniz, SJA; Liu, Y; Liu, X; Li, Y; ...
