Enhanced Solar CO2 Photoreduction to Formic Acid by Platinum Immobilization on Bipyridine Covalent Triazine Framework with Defects

Abstract: The immobilization and structural analysis of platinum nanoparticles on a nitrogen‐rich, bipyridine‐containing covalent triazine framework (bpyCTF) having structural defects are disclosed by taking advantage of 15N solid‐state nuclear magnetic resonance measurements at natural 15N isotope abundance and X‐ray photoelectron spectroscopic analyses. The photocatalyst (Pt@bpyCTF) with structural defects reduces CO2 to formic acid (FA) at a rate of 152 µmol h−1g−1 and a selectivity higher than 95% over CO and H2 in … Show more

“…Postsynthetic introduction of primary amine groups or the presence of unreacted amino or carbonyl groups in imine-linked COFs have been shown to result in functional properties that are otherwise difficult to attain in fully formed networks. [98][99][100][101] In this context, several synthetic strategies, including functional group interconversions, [102][103][104][105] transamination reactions, 106,107 and siteselective [108][109][110][111][112] and regioselective synthesis, 113 have been reported to introduce primary amine groups in 2D COFs.…”
