Accelerating photocatalytic hydrogen production by anchoring Pt single atoms on few-layer g-C₃N₄ nanosheets with Pt–N coordination

Abstract

Graphitic carbon nitride (g-C3N4) has gained considerable attention as a promising photocatalyst for hydrogen production through water splitting. However, its catalytic efficiency remains severely limited due to the rapid recombination...

Unlocking the potential of V2O5 decorated on crossed g-C3N4 monolayers derived from synergistic bio-transformation of ZnMn2O4 for antibiotic photodegradation

“…5(d), bi-exponential fitting of eqn (S11)† was used to retrieve T 1 and T 2 , which are associated with the fast decay of short-lifetime charge carriers in direct excitation recombination and the slow decay of long-lifetime charge carriers through indirect recombination, respectively. 59 The uncertainty values of each sample for this fitting were provided in Table 1. Considering A 1 and A 2 as the corresponding amplitudes, the proportion of long-lifetime (( A 2 T 2 )/( A 2 T 2 ) + ( A 2 T 2 )) was enhanced to 86% in Z -schematic (6)ZM/CCN compared with precursors (6)ZM and TCN with the long-lifetime proportions of 74% and 64%, respectively (more information is available in Table S2†).…”

Rapidly chemical preparation of Mn doped ZnO nanostructures for photocatalysis efficiency based on UV light system and mechanism insights

“…The absorbance spectrum of the acceptor overlaps with the emission spectrum of the donor, resulting in the occurrence of FRET between the donor and acceptor dipoles. In photocatalytic degradation, when the absorbance spectra of dye and emission spectra of the catalyst overlap, FRET (Forster Resonance Energy Transfer) occurs between the catalyst and dye [53][54][55]. In the event that the emanation spectra of catalysts covers with the absorbance range of the dye, energy released by catalyst in the recombination process, transfer by nonradiatively to the dye (FRET).…”
