Boosting non-sacrificial H₂O₂ production on a Bi₆S₂O₁₅ photocatalyst via creating a crystal surface-dependent internal electric field

Abstract

Photocatalytic H2O2 production from H2O and O2 is a green technology, but the available photocatalysts are limited, due to the severe recombination caused by multiple-step charge transfer. In this work,...

Arene–perfluoroarene interactions in molecular cocrystals for enhanced photocatalytic activity

“…Subsequently, e − and h + are continuously moving and recombining and then transferred to cocrystal catalyst surfaces for further redox reactions. 44 The strong AP interactions in the cocrystals have been demonstrated by spectroscopic analysis, and the effects of AP interaction on the photogenerated carrier behaviour, energy band structure, and photocatalytic performance are detailed and discussed in this section.…”

Enhancing the internal electric field via twinning for boosting photocatalytic plastic reformation and H2 production

“…As a dynamic driving force, the strong built IEF facilitates better separation of the photogenerated hole–electron pairs. We studied the influence of constructing twinned structures on the IEF intensity in ZnSe using the Kanata model, based on the following equation: 50–52 F s = (−2 V s ρ / εε 0 ) 1/2 …”

Boosting hydrogen peroxide production of brookite TiO2 with Au and MXene co-catalysis under UV light

“…The concentration of H 2 O 2 was determined using a digital PACKTEST spectrometer (model ED723 from GL Sciences Inc.). 28,29…”
