A Nitrogen-Rich Covalent Triazine Framework as a Photocatalyst for Hydrogen Production

Figure 6

TEM images for (a–d) Pt/CTF-CN following the H2 production tests and (e, f) Pt/g-C3N4. The Pt nanoparticles were formed by the photoreduction of hexachoroplatinate ions in a H2O/TEOA/CH3OH (85 : 10 : 5 by volume) mixture with photocatalyst exposure to a 300 W Xe lamp. (g) Pt 4f XPS spectra for CTF-CN, Pt/CTF-CN, g-C3N4, and Pt/g-C3N4. For the CTF-CN and Pt/CTF-CN, the Br 3d peaks also appear in this spectral region (for the curve fits, pink = Br 3d, green = Pt0, and red = Pt2+).
