Covalent Triazine Framework Anchored with Co3O4 Nanoparticles for Efficient Oxygen Reduction

Graphical Let's synergize ORR : A novel hybrid catalyst of Co 3 O 4 and covalent triazine framework (CTF) is prepared through the in situ growth of Co 3 O 4 nanoparticles on CTF by using a hydrothermal method. This novel oxygen reduction reaction (ORR) catalyst shows a synergistic catalytic effect as well as comparable activity to the commercial Pt/C ORR catalyst (see picture). The oxygen reduction reaction (ORR) is an important process in energy conversion and storage devices. Great efforts have been focused on developing efficient, durable, and low-cost non-Pt catalysts. In this study, a novel hybrid ORR catalyst of Co 3 O 4 and covalent triazine framework (CTF) was prepared through the in-situ growth of Co 3 O 4 nanoparticles on CTF by using a hydrothermal method. Systematical studies revealed that this hybrid catalyst not only has a synergistic catalytic effect in the ORR, but also has superior stability and better methanol resistance than commercial Pt/C catalysts.
