Shaping Covalent Triazine Frameworks for the Hydrogenation of Carbon Dioxide to Formic Acid

Abstract

What was the inspiration for this cover design? We aimed to artistically depict the way our shaped catalyst looks like. During the preparation of the spheres CTF powder was dispersed in an orange-yellow Matrimid solution-that is how the idea to picture the binder as ap ouring honey stream developed.

Covalent organic frameworks as supports for a molecular Ni based ethylene oligomerization catalyst for the synthesis of long chain olefins

“…With the aim of exploring the suitability of different highly In contrast, adsorption isotherms on both CTF materials ( Figure 2) show the fully microporous nature of micro-CTF and the micro-meso porous character of meso-CTF, in good agreement with our previous results [73,76]. Table 1 summarizes the main textural properties of the different supports and catalysts.…”

Covalent Triazine‐based Frameworks—Tailor‐made Catalysts and Catalyst Supports for Molecular and Nanoparticulate Species

“…In the following years, Bavykina et al. expanded the research scope for the Ir III Cp*@CTF system by shaping it for CO 2 hydrogenation applications . Using polyimide Matrimid ® as a binder, porous and rigid catalyst spheres of few millimeters in diameter became accessible after precipitation and successive activation at 350 °C under nitrogen flow.…”

Even though partial polymer chain penetration into the CTF led to substantial pore blockage, mesoporosity of the system could partially be preserved.…”

Continuous Hydrogenation of Carbon Dioxide to Formic Acid and Methyl Formate by a Molecular Iridium Complex Stably Heterogenized on a Covalent Triazine Framework

“…[10] Catalytic activity of iridium molecular complexes immobilized on different CTFs in CO 2 hydrogenation to formate/formic acid has been demonstrated. [11] Despite the success, the catalytic tests are performed under batch conditions, thus failing to discern if the catalytic activity arises from either a leached or heterogenized complex. Furthermore, significant challenges regarding catalyst stability especially under continuous operation, elucidation of intermediate species and accessibility of the active sites remain to be addressed, before the viability of such catalysts can be critically assessed for potential industrial applications.…”
