A solar cell for maximizing voltage up to the level difference of two photocatalysts: optimization and clarification of the electron pathway

“…Under light and an O 2 atmosphere (Fig. 9A), the redox of the Bi 0/3+ species via eqn (4) and (5) 16,18,27,28 The O 2 reduction reaction is indirectly monitored as the more negative slope of the reduction wave in Fig. 9A and B, in comparison to that in Fig.…”

Enhanced Photocatalytic Activity by Cu2O Nanoparticles Integrated H2Ti3O7 Nanotubes for Removal of Mercaptan

“…Among organic pollutants, sul¯des are major pollutants and they are di±cult to remove utterly. [1][2][3] Sul¯des often exist in hydrocarbons as pollutants. It is one of the most di±cult sulfur compounds to remove from liquid fuels.…”

One‐Step and Surfactant‐Free Fabrication of Gold‐Nanoparticle‐Decorated Bismuth Oxychloride Nanosheets Based on Laser Ablation in Solution and Their Enhanced Visible‐Light Plasmonic Photocatalysis

“…[3,4] The bismuth-oxide-based fluorite-like layer and the resultanti nternal static electric fields perpendicular to the [Bi 2 O 2 ]e nablethe effective separation of the photoinduced electron-hole pairs along the [001] direction, whicha ffords BiOCl excellent photocatalyticp erformance.
