“…Thus, high temperatures and CO 2 pressures are also required here and significant amounts of energy are necessary as well as specific equipment. Numerous articles describe harsh conditions; − high temperatures ranging from 80 to 100 °C and CO 2 pressures (up to 100 atm) were reported. The yields are fairly high in the majority of the cases but show a wide range from 11% to 97%.…”

The synthesis of cyclic carbonates, substrates gaining growing interest due to their broad spectrum of applications, is analyzed from a Green Chemistry perspective. Extensive research has been carried out on the synthesis of these substances, which are of interest especially for the preparation of so-called non-isocyanate polyurethanes (NIPUs). Often, the renewability of the raw materials, derived for instance from carbon dioxide, diols, urea, or alkyl carbonates, is taken into account, without considering sustainability aspects of their synthesis protocols. In this review, we employ E-factors and discuss basic toxicity information to compare numerous approaches and data reported in the literature for synthesizing the most common cyclic carbonates to provide a useful, although not exhaustive, first sustainability evaluation. This study highlights that to achieve a more sustainable manufacture of cyclic carbonates, the renewability of the starting materials has to be matched with safer chemicals and mild and efficient reaction protocols in order to limit the environmental impact of their synthesis.

“…3) Oxidation carboxylation of styrenes (a kind of olefins) with CO 2 in the presence of oxidants, as seen in Scheme 3 (Figure 5). Three types of catalysts with DMSNs as the supports have been constructed, being dual 1,4‐diazabicyclo[2.2.2]octane‐based ionic liquid (④ DABCO‐based DMSNs‐DIL), [ 89 ] a platinum complex (⑤ DMSNs‐Pt(II)), [ 90 ] and a magnetic Pd‐implanted Schiff base complex coupled with imidazolium‐based ionic liquid (⑥ FeNi 3 @DMSNs‐DIL/Pd(II)/Salen). [ 91 ] It should be mentioned that a magnetic core was introduced before the subsequent organic modifications for FeNi 3 @DMSNs.…”

Dendritic mesoporous silica nanoparticles own three‐dimensional center‐radial channels and hierarchical pores, which endows themselves with super‐high specific surface area, extremely large pore volumes, especially accessible internal spaces, and so forth. Dissimilar guest species (such as organic groups or metal nanoparticles) could be readily decorated onto the interfaces of the channels and pores, realizing the functionalization of dendritic mesoporous silica nanoparticles for targeted applications. As adsorbents and catalysts, dendritic mesoporous silica nanoparticles‐based materials have experienced nonignorable development in CO2 capture and catalytic conversion. This comprehensive review provides a critical survey on this pregnant subject, summarizing the designed construction of novel dendritic mesoporous silica nanoparticles‐based materials, the involved chemical reactions (such as CO2 methanation, dry reforming of CH4), the value‐added chemicals from CO2 (such as cyclic carbonates, 2‐oxazolidinones, quinazoline‐2,4(1H,3H)‐diones), and so on. The adsorptive and catalytic performances have been compared with traditional silica mesoporous materials (such as SBA‐15 or MCM‐41), and the corresponding reaction mechanisms have been thoroughly revealed. It is sincerely expected that the in‐depth discussion could give materials scientists certain inspiration to design brand‐new dendritic mesoporous silica nanoparticles‐based materials with superior capabilities towards CO2 capture, utilization, and storage.
