Linker functionalized poly(heptazine imide) as charge channel and activation site for enhancing photocatalytic nitrogen fixation in pure water

NH-rich red poly(heptazine imide) nanoparticles with simultaneously promoted exciton dissociation and activated n → π* electronic transition for boosted photocatalytic H2 generation

“…5f), owing to the synergetic effect of the nanoparticle structures and the n → π* transition. 47,48 Besides this, compared with PHI, the slightly increased photocurrent density of the RPHI1 NP under λ > 420 nm light irradiation benefits from its nanoparticle structure (inset in Fig. 5f).…”

A bioinspired floatable system with a 3D sandwich-type triphase interface for highly efficient nitrogen fixation

“…Amorphous carbon is represented by the peak at 284.80 eV, while the peak at 286.20 eV is ascribed to the CN of melamine. 69–71 Accordingly, at room temperature, we acquired powder X-ray diffraction (XRD) patterns of BiVO 4 , MS, PDMS@MS, BiVO 4 @MS (the separate XRD pattern of BiVO 4 @MS is given in Fig. S5†), and BiVO 4 @PDMS@MS and investigated their crystalline phases, respectively (Fig.…”

Edge- and bridge-engineering-mediated exciton dissociation and charge separation in carbon nitride to boost photocatalytic H2 evolution integrated with selective amine oxidation

“…Firstly, formaldehyde solution reacted with melem units to produce hydroxyl-rich precursors under alkaline conditions. 35 As illustrated in Fig. S2b (ESI), † the precursor sample exhibits a rod-like appearance with a rough surface.…”
