Ordered layered N-doped KTiNbO5/g-C3N4 heterojunction with enhanced visible light photocatalytic activity

Visible-light-driven Ag/Bi3O4Cl nanocomposite photocatalyst with enhanced photocatalytic activity for degradation of tetracycline

“…Samples for ESR measurement were prepared as follows: 10.0 mg sample was dissolved in 0.5 mL methanol, and 45 mL DMPO was added with ultrasonic dispersion for 5 min to form DMPO -cO 2À ; 0.5 mL deionized water was used in place of methanol to form DMPO -cOH. 34,35 3. Results and discussion…”

2D Titanium/Niobium Metal Oxide‐Based Materials for Photocatalytic Application

“…As a typical metal‐free semiconductor, g‐C 3 N 4 has been extensively applied in photocatalytic fields for the degradation of pollutants, H 2 production, and CO 2 reduction due to its characteristics of moderate bandgap (≈2.7 eV), low cost, nontoxicity, good stability, easy preparation, and suitable electronic band structure . Since g‐C 3 N 4 was first reported for the photocatalytic H 2 evolution by Wang et al, much attention has been paid to improve the photocatalytic activity by combining g­C 3 N 4 with other 2D TNMOs such as KTiNbO 5 , HCa 2 Nb 3 O 10 , KCa 2 Nb 2 TaO 10 , N‐doped La 2 Ti 2 O 7 , 2D TiO 2 NSs, and SnNb 2 O 6 NS …”

Facile synthesis of C, N-TiO2 nanorods via layered Ti 3 O 7 2 − -TMAH interlaminar bonding interaction and their enhanced catalytic performance

“…Non-metallic of C and N elements doping can introduce impurity levels around at O 2p band level. It can inhibit the recombination of photon-generated carriers, which can effectively increase the electrons and holes used in the radical reaction [30,[35][36][37]. However, excessive N element doping would inhibit the catalytic rate, as shown in figure S2.…”
