2D covalent organic frameworks (COFs) are drawing intense attention in heterogenous photocatalysis due to their porous, crystalline, and tailor‐made structures. For highly efficient solar‐to‐chemical energy conversion, revealing and modulating active centers in the skeletons of COFs are of great importance but encounter severe challenges. Herein, i...

Developing photocatalysts with improved photoactivity and efficiency has remained an enduring theme both fundamentally and technologically in the field of photocatalysis. Polymeric carbon nitride (CN) has been widely exploited as an earth-abundant photocatalyst for water redox reactions. Nevertheless, the limited visible-light utilization rate and...

The design of metal-free photocatalysts has drawn considerable attention in photocatalysis due to the merits of low cost, sustainability, and recyclability without releasing toxic metals from photocorrosion. As an emerging metal-free photocatalyst, covalent triazine-based framework (CTF) has stimulated great research interests in photochemical wate...

... In addition, the photocatalytic activity of semiconductor photocatalysts also depends on their conduction band (CB) and valence band (VB) level. The VB-X-ray photoelectron spectroscopy (XPS) tests reveal the VB levels of Te-COFs are 1.58 eV (TeTpb-COF), 1.45 eV (TeTf-COF), 1.75 eV (TeTt-COF) ( Fig. S8) [33], respectively. Therefore, the CB positions of the TeTpb-COF, TeTf-COFs, and TeTt-COF are −0.17, ...
... The survey spectrum ( Figure S3) and highresolution spectra (Figure 2d) confirm the presence of the oxidation states of Cu(I) (2p 1/2 , 952.1 eV and 2p 2/3 932.2 eV), In(III) (3d 3/2 , 452.2 eV and 3d 5/2 ,444.7 eV), and Se(II) (3d 3/2 , 55.1 eV and 3d 5/2 , 54.2 eV). 40 The surface modification of CuInSe 2 NCs is proved by the appearance of a notable S 2p signal in (NH 4 ) 2 S-treated NCs. The S 2p spectrum exhibits two peaks at 166.2 and 160.8 eV. ...
... It is expected to raise the yield of p-cymene, increase the stability and recyclability of the catalyst, and make the reaction conditions more moderate by selecting suitable support to deposit noble metals. Covalent triazine framework (CTF) is a kind of covalent organic framework material that has the characteristics of nitrogen-rich, organic conjugated structure and good stability, and is a promising catalyst support in heterogeneous catalysis [30][31][32]. CTF is composed of aromatic N-C=N structure of triazine ring unit by covalent bond. However, most CTF materials have the problem of high exciton binding energy and weak electron transport capacity [33,34]. ...
