Quantum yield enhancement in the photocatalytic HCOOH decomposition to H₂ under periodic illumination

Abstract

Despite numerous studies on controlled periodic illumination to improve the quantum yield of photocatalytic reactions, debates still exist on the nature of the enhancement effect. Here, we report the promotion...

Photocatalytic selective conversion of furfural to γ-butyrolactone through tetrahydrofurfuryl alcohol intermediates over Pd NP decorated g-C3N4

“…The intense peak at 27.7°corresponds to plane (002), portrays the graphitic nature of the materials, and belongs to the standard interlayer stacking structure of g-C 3 N 4 (JCPDS87-1526). 37 Another weak diffraction peak at 13.1°signies the (100) plane, conrming the interplanar structural packing in g-C 3 N 4 . 38 Upon ultrasonication, exfoliation of the layered Scheme 2 Schematic presentation for the synthesis of g-C 3 N 4 and X% Pd@E-g-C 3 N 4 .…”

Oxygen vacancies enhance the photocatalytic deep oxidation of NO over an N-doped KNbO3 catalyst

“…The photocurrent of the KNbO 3 catalyst showed that the introduction of non-metallic element N can improve the separation efficiency of photogenerated electrons and holes. 32 Moreover, Fig. 4b shows the electrochemical impedance spectra (EIS).…”

Remarkably improved photocatalytic selective oxidation of toluene to benzaldehyde with O2over metal-free delaminated g-C3N4nanosheets: synergistic effect of enhanced textural properties and charge carrier separation

“…The apparent quantum yield (AQY) was calculated following a reported method. 40 The details of photocatalytic reactions, photocatalytic reactor set-up, quantification of conversion, selectivity (Fig. S1), and AQY are provided in the ESI †.…”
