Fabrication of uniformly dispersed Ag nanoparticles loaded TiO 2 nanotube arrays for enhancing photoelectrochemical and photocatalytic performances under visible light irradiation

Preparation and photocatalytic CO2 reduction performance of silver nanoparticles coated with coal-based carbon dots

“…Figure 2 shows the TEM results of experimentally prepared CDs, Ag, and Ag/CDs. 27 These results prove that the prepared products are Ag/CDs composite particles formed by CDs coated on Ag. The particle size distributes uniformly between 4 to 5 nm.…”

A facile strategy to fabricate plasmonic Cu modified TiO 2 nano-flower films for photocatalytic reduction of CO 2 to methanol

“…Recently, noble metal nanoparticles (NPs) have been widely investigated to improve the efficiency of photocatalytic processes due to their localized surface plasmon resonance (LSPR) effect [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Under appropriate light irradiation, the excitation of localized plasmon polaritons on the surface of metal NPs results in a substantial increase in the near-field amplitude, leading to considerable enhancement of the electric near-field in the vicinity of the metals.…”

Preparation of Bi2Ti2O7/TiO2 nanocomposites and their photocatalytic performance under visible light irradiation

“…The surface chemical composition was measured by X-ray photoelectron spectroscopy (XPS, Krato Axis Ultra DLD) with Al Kα X-ray at 15 kV and 150 W. Photocurrent response was measured in a standard three-electrode cell with a quartz window by electrochemical workstation (CHI 660D Instruments Inc., Shanghai) using a 0.5 M Na 2 SO 4 aqueous solution as the electrolyte under visible light (λ N 400 nm, 100 mW/cm 2 ) irradiation. The photocatalytic activity was measured in a XPA-II photochemical reactor according to our previous report [23].…”
