“…37) O 1s at 529.9 eV in HKTS/TiO 2 composites attributed to the Ti-O band. 38 In Fig. 4(b), the binding energies of Sn 3d 3/2 (494.5 eV) and Sn 3d 5/2 (486.1 eV) of HKTS indicate that the chemical state of Sn is Sn 4+ .…”

Impact of Titanium Dioxide (TiO2) Modification on Its Application to Pollution Treatment—A Review

“…Nitric acid oxidation treatment of CF generated polar functional groups, which improved the bonding properties between TiO2 and CF. Hu et al [54] Glass has good light transmission properties and is easy to make into photoreactors with different shapes. Therefore, glass-based carriers have also received widespread attention.…”

“…Nitric acid oxidation treatment of CF generated polar functional groups, which improved the bonding properties between TiO 2 and CF. Hu et al [54] prepared 3D flower-like g-C 3 N 4 /TiO 2 composite spherical materials (FCTCMs) using a simple solvothermal method and studied their photocatalytic performance. The results showed that the photocatalytic performance of FCTCMs under visible light was twice that of FTMs (3D flower-like structure of TiO 2 microspheres) because g-C 3 N 4 can broaden the photoresponse range and reduce the recombination rate of photogenerated electron-hole pairs.…”

NiCo2O4/g‐C3N4 Heterojunction Photocatalyst for Efficient H2 Generation

“…Figure 4b shows the high-resolution spectrum of C 1s, revealing four characteristic peaks: the peaks at 284.8 and 286.45 eV were assigned to C─C and C─N, respectively, the peak at 288.17 eV was assigned to the s-triazine species N═C─N, and the peak at 293.59 eV was attributed to π-excitation. [5,34,43,44] Figure 4c shows the highresolution spectrum of N 1s, revealing four characteristic peaks at 398.59, 400.17, 401.26, and 404.47 eV, which correspond to sp 2 -hybridized C═N─C, N─(C)3, C─N─H, as well as π-excitation. [11,22,44,45] Figure 4d,e shows the high-resolution XPS spectra of Co 2p and Ni 2p.…”

“…[1][2][3] In 1972, after the Japanese scientist Fujisjima discovered that TiO 2 produces H 2 by the photolysis of water, photocatalytic H 2 production technology has received widespread attention. [4] At present, many semiconductor photocatalysts are used for H 2 production from water splitting, such as TiO 2 , [5,6] WO 3 , [7,8] CdS, [9,10] MoS 2 , [11,12] and g-C 3 N 4 . [13,14] Nanosheets of g-C 3 N 4 have attracted extensive interest because of the flexible layered structure and suitable bandgap (%2.7 eV).…”
