Removal of Nitric Oxide through Visible Light Photocatalysis by g-C3N4 Modified with Perylene Imides
Abstract
For photocatalytic removal of nitric oxide (NO), two major issues need to be addressed: incomplete oxidation of NO and deactivation of the photocatalyst. In this study, we aimed to solve these two problems by constructing an all-solid-state Z-scheme heterojunction (PI- g -C 3 N 4 ) consisting of g-C 3 N 4 surface modified with perylene imides (PI). PI- g -C 3 N 4 exhibits significant enhancement in photocatalytic activity (in comparison to pristine g-C 3 N 4 ) when examined for NO removal. More importantly, the Z-scheme charge separation within PI- g -C 3 N 4 populates electrons and holes into the increased energy levels, thereby enabling direct reduction of O 2 to H 2 O 2 and direct oxidation of NO to NO 2 . H 2 O 2 can further oxidize NO 2 to NO 3 – ion at a different location (via diffusion), thus alleviating the deactivation of the catalyst. The results presented may shed light on the design of visible photocatalysts with tunable reactivity for application in solar energy conversion and environmental sustainability.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
