Kinetic pathways of sub-bandgap induced electron transfer in Ag/TiO₂ and the effect on isopropanol dehydrogenation under gaseous conditions

Abstract

Ag nanoparticles mainly play the cocatalytic role of the relaxation of the electrons generated in TiO2 from the valance band to the conduction band under subbandgap light illuminations.

Commonly Existing Hole-Capturer Organics Adsorption-Induced Recombination over Metal/Semiconductor Perimeters: A Possible Important Factor Affecting Photocatalytic Efficiencies

“…The gas-phase photocatalytic performances of all samples were assessed by studying the isopropyl alcohol dehydrogenation to acetone. The photocatalytic experiments were carried out in a self-designed closed-loop cylindrical batch reactor of pure quartz glass according to our previous study . The photocatalytic reactor was heated to a set temperature by a heating plate underneath the reactor, varying between 40 and 80 °C with an interval of 20 °C.…”

“…The photocatalytic experiments were carried out in a self-designed closed-loop cylindrical batch reactor of pure quartz glass according to our previous study. 33 The photocatalytic reactor was heated to a set temperature by a heating plate underneath the reactor, varying between 40 and 80 °C with an interval of 20 °C. The above 375 nm laser was used as the light source for light illumination; it provides monochromic near-UV light illumination.…”
