Abstract The distribution of catalytic active sites critically dictates photocatalytic efficiency, but existing catalyst design operate at the same or adjacent sites still remain limitations toward photocatalytic reaction. To address this, a kind of spatially separable oxidation-reduction assignment in fluorine substituted molecular organic junction catalyst (covalent triazine framework, CTF-TF-0.5) is constructed.

Coal chemical industry generates large volumes of wastewater from processes like coal washing, cooling water circulation, and chemical reagents addition [1]. It is characterized by high concentrations of chemical oxygen demand (COD), salts (such as, Na+, Cl−, and SO42-), ammonia, and nitrogen heterocyclic substances (NHCs) (such as, pyridine, quinine, and indole) [2], [3], [4]. In particular, the presence of NHCs poses a significant challenge to achieve first-level discharge standards [5].

Emerging contaminants (ECs), as a number of unregulated or incompletely regulated compounds, including antibiotics, steroid hormones, plasticizers, antimicrobials and so on [1]. These pollutants and their derivatives are toxic to humans and animals in a variety of ways, including neurotoxicity, organ toxicity, immunotoxicity, and carcinogenicity and teratogenicity [2].
