“…Highly accessible accordion‐like structure of Ti 3 C 2 T z ‐40HF‐24 MXene as well as the presence of accessible Ti−O active species determine their higher catalytic activity. Interestingly, the performance of Ti 3 C 2 T z keeps up with the best catalysts reported so far for this reaction, including metal‐incorporated zeolites, [43–46] metal oxides, [44,47,48] as well as metal‐Schiff base complexes [49] and metalloporphyrins [50] homogeneous catalysts (see Table S1). Thus, MXenes emerge as a novel class of heterogeneous catalysts for the synthesis of benzaldehyde from styrene and oxidation reactions in general.…”

Ti3C2Tz MXenes are prepared under different etching conditions and tested as heterogeneous catalysts for the selective oxidation of styrene to benzaldehyde. A clear dependence is observed between the etching conditions (hydrofluoric acid concentration and etching time) and the surface chemistry, morphology and catalytic performance of the resulting MXenes. Under appropriate conditions, etching of the Ti3AlC2 MAX phase precursor with concentrated HF produces Ti3C2Tz MXenes with highly accessible accordion‐like structures and accessible Ti‐O surface terminations that can act as active species for the catalytic process, keeping up with the best catalysts reported so far for this reaction. The present study represents one of the few existing reports on catalytic properties of MXenes under mild liquid‐phase conditions, paving the way for future developments of this new family of 2D materials for fine chemical applications.

“…In 2014, Jury et al reported the synthesis of a new and efficient Co-ZSM-11 catalyst for the selective styrene oxidation to benzaldehyde [ 42 ]. The ZSM-11 zeolite was synthesized by a hydrothermal process and further doped by the ionic exchange as previously reported [ 5 ], obtaining Co-ZSM-11 zeolite that was fully characterized.…”

The selective oxidation of styrene under heterogeneous catalyzed conditions delivers environmentally friendly paths for the production of benzaldehyde, an important intermediate for the synthesis of several products. The present review explores heterogeneous catalysts for styrene oxidation using a variety of metal catalysts over the last decade. The use of several classes of supports is discussed, including metal–organic frameworks, zeolites, carbon materials and silicas, among others. The studied catalytic systems propose as most used oxidants tert-butyl hydroperoxide, and hydrogen peroxide and mild reaction conditions. The reaction mechanism proceeds through the generation of an intermediate reactive metal–oxygen species by catalyst-oxidant interactions. Overall, most of the studies highlight the synergetic effects among the metal and support for the activity and selectivity enhancement.

“…However, due to the poor selectivity, difficulty in separation and recycling of these homogeneous catalysts, it is a matter of the utmost urgency to develop highly active, selective, and reusable heterogeneous catalysts for economical and eco‐friendly oxidation of alkenes. Many heterogeneous catalysts, including metal oxides, [34–40] polyoxometalates (POMs), [41–44] and zeolites‐, silica‐ or carbon materials‐supported metal nanoparticles [45–65] have been developed for the oxidation of styrene. However, the poor selectivity of many of these catalysts in converting styrene to benzaldehyde impels further development of catalysts.…”

Chemoselective Oxidation of Alkenes by Metal‐Organic Framework‐Supported Copper Catalyst

Oxidation of alkenes to carbonyls or diols compounds is important in synthesizing fine chemicals and pharmaceutical intermediates. We report the synthesis and characterization of an aluminum metal‐organic framework node‐supported copper(II) chloride (DUT‐5‐CuCl), which is an efficient heterogeneous catalyst for the oxidation of alkenes using H2O2 as an oxidizing agent. Styrene and various substituted styrenes were transformed into the corresponding carbonyl compounds in excellent selectivity and yields. DUT‐5‐CuCl is tolerant with various functional groups and could be recycled and reused at least 5 times in the oxidation of α‐methylstyrene. Unlike the oxidation of styrene derivatives, DUT‐5‐Cu catalyzed oxidation of aliphatic and cyclic alkenes produced 1,2‐diols compounds selectively. The mechanism of the DUT‐5‐Cu catalyzed oxidation of styrene to benzaldehyde was investigated in detail by various experiments such as the determination of reaction intermediates and characterization of the catalyst after catalysis, and computational studies. This work highlights the importance of MOF‐supported earth‐abundant metal catalysts for oxidation reactions to produce fine chemicals.
