Covalent triazine frameworks (CTF) have been recently applied as supports for metal catalysts for different reactions. Varying the nature of the CTF support could improve catalytic properties due to a change in the nature of metal active sites presented in the form of single atoms and dispersed nanoparticles. To understand these changes, for the first time, 1 wt % Pd catalysts supported on hatnCTF and acacCTF prepared from hexaazatrinaphthylene-tricarbonitrile and malonyldibenzonitrile, respectively, were tested in formic acid decomposition in the gas phase. The results were compared with those obtained for a Pd/g-C3N4 catalyst. The catalysts were characterized by high-angle annular dark-field/scanning transmission electron microscopy, X-ray absorption near edge structure/extended X-ray absorption fine structure and X-ray photoelectron spectroscopy. The activity of the Pd/hatnCTF catalyst was significantly higher than those for Pd/acacCTF and Pd/g-C3N4, providing the reaction at a lower temperature by ∼60 K. The high performance of this catalyst was attributed to single-atom Pd2+–C1N3 sites, which are the main active Pd species in this sample. The Pd/acacCTF sample contained single-atom Pd2+–O4 sites and metallic Pd nanoparticles, while the Pd/g-C3N4 sample contained mainly metallic Pd nanoparticles. The selectivity toward H2 was high (>98%) for all catalysts even at 573 K. The obtained results could be useful for the development of different applications of CTF materials.
