Incorporation of Cu2O nanocrystals into TiO2 photonic crystal for enhanced UV–visible light driven photocatalysis

Preparation of Cu2O@TiOF2/TiO2and its photocatalytic degradation of tetracycline hydrochloride wastewater

“…TiO 2 has good chemical and biological stability, but it has become a bottleneck for development due to its low light utilization and fast photocarriers recombination. [16][17][18][19] To change this situation, many studies have enhanced the response of TiO 2 in the visible region by doping TiO 2 with non-metals (C, N, F, S, etc.) 2,[20][21][22] and semiconductors (Cu 2 O, CdS, etc.).…”

“…2,[20][21][22] and semiconductors (Cu 2 O, CdS, etc.). 17,23,24 The introduction of F ions can greatly change the performance of TiO 2 , and titanium oxydiuoride can be formed when TiO 2 is in a high concentration of F ions. TiOF 2 as a semiconductor material has gradually appeared in the eld of photocatalysis.…”

Photocatalytic performance of Cu2O-loaded TiO2/rGO nanoheterojunctions obtained by UV reduction

“…For example, Wang or Geng et al [14, 23] synthesized nanocrystalline Cu 2 O on TiO 2 frame or arrays using cupric acetate as precursor and glucose as reducing reagent. Gao et al [24] loaded Cu 2 O particle on rGO sheet using l -ascorbic acid as reductive reagent in mild condition.…”

One-pot synthesis of Cu2O/C@H-TiO2 nanocomposites with enhanced visible-light photocatalytic activity

“…Notably, according to previous reports, 34 the binding energy of Cu + is located at 934 and 952.5 eV, therefore, the measured Cu2p binding energy may be the result of an adjustment synergy between the heterojunction structure between Cu 2 O and TiO 2 and the amorphous carbon doping. 19,37,42 The Fig. 5 indicates the N 2 adsorption-desorption isotherms and pore size distributions of H-TiO 2 and Cu 2 O/C@H-TiO 2 .…”
