Abstract:
Here, we report a hydrogen-bond bridging strategy to combine carboxylated nanocellulose (f-CNF) with nitrogen-rich carbon nitride (C3N5). This strategy constructs a hydrogen-bond network that spatially facilitates the transfer of photogenerated charge carriers and the rapid supply of protons through interactions with C3N5. More critically, the carboxyl-rich f-CNF serves as an efficient proton donor to drive the directional migration of protons from f-CNF to C3N5, accurately enriching electron accumulation sites with protons and achieving synchronous conversion of protons and electrons. As a result, the catalyst presents a high H2O2 production rate of 1473 µmol L-1 h-1.

Photosystem I
Both these photosystems work in concert. An excited electron from PSII is relayed to PSI via an electron transport chain in the thylakoid membrane of the chloroplast, which is comprised of the carrier molecule plastoquinone, the dual-protein cytochrome complex, and plastocyanin. As electrons move between PSII and PSI, they lose energy and must be re-energized...
