[24,27] Raman spectrum was analyzed in the Supporting Information, TheU V/Vis absorption spectrum of the CN is shown in Figure 3a.T he absorption edge of the CN reached 735 nm, which far exceeded the values for PCN and the precursors (Supporting Information, Figure S14). [28] Ab and gap of 1.68 eV was calculated for the CN (Figure 3a Inset).…”

Metal-free carbonitride(CN) semiconductors are appealing light-transducers for photocatalytic redox reactions owing to the unique band gap and stability. To harness solar energy efficiently, CN catalysts that are active over a wider range of the visible spectrum are desired. Now a photochemical approach has been used to prepare a new-type triazine-based CN structure. The obtained CN shows extraordinary light-harvesting characteristics, with suitable semiconductor-redox potentials. The light absorption edge of the CN reaches up to 735 nm, which is significantly longer than that of the conventional CN semiconductor at about 460 nm. As expected, the CN can efficiently catalyze oxidation of alcohols and reduction of CO with visible light, even under red-light irradiation. The results represent an important step toward the development of red-light-responsive triazine-based structures for solar applications.

“…The alterations induced in polymers due to swift heavy ion irradiation are of great curiosity. The spectacular alterations acquainted in the irradiated polymers are due to main-chain scission and cross linking [1]. The changes stimulated in the polymers not only depend upon the energy of the irradiating ions, but also on the ion species [2].…”
