“…2D-COF-2 relies on the super-stability of the olefin chains to maintain its basic structure and photoactivity under strongly acidic conditions. Furthermore, the structure, porosity, and crystallinity of the catalysts were confirmed by 13 C solid-state NMR spectroscopy, Fourier transform infrared (FT-IR) spectroscopy, N 2 adsorption measurements, and powder X-ray diffraction (PXRD). In addition, its potential for industrialisation in recycling experiments, functionalisation of bioactive molecules, and scale-up reactions has been demonstrated.…”

In recent years, Web of Science has published nearly one hundred reports per year on quinoxalin-2(1H)-ones, which have attracted great interest due to their wide applications in pharmaceutical and materials fields, especially in recyclable heterogeneous catalytic reactions for direct C–H functionalisation. This review summarises for the first time the methods and reaction mechanisms of heterogeneous catalytic reactions of quinoxalin-2(1H)-ones, including six major types of heterogeneous catalysts involved. The heterogeneous reactions of quinoxalin-2(1H)-ones are summarised by classifying different types of catalytic materials (graphitic phase carbon nitride, MOF, COF, ion exchange resin, piezoelectric materials, and microsphere catalysis). In addition, this review discusses the future development of heterogeneous catalytic reactions of quinoxalin-2(1H)-ones, including the construction of C-B/Si/P/RF/X/Se bonds by heterogeneous catalytic reactions, the enrichment of heterogeneous catalysts such as metal oxides, graphene-based composites, doped metal nanoparticles, and molecular sieve-based porous materials, asymmetric synthesis, and other areas. The aim of this review is to contribute to the development of green and sustainable heterogeneous reaction methods for quinoxalin-2(1H)-ones with applications in materials chemistry and pharmacology.

“…Under the reaction conditions of 3 wt.% catalysts, 20:1 methanol/oil molar ratio, 200 • C reaction temperature, 3.9 MPa reaction pressure, and 600 r/min stirring speed, 99.57% fatty acid methyl esters (FAME) conversion was achieved within 180 min. 9 Lu et al fabricated core-shell P[xSPA-yDABCO]@SiO 2 @Fe 3 O 4 composites materials with a shell of photo-responsive and base catalytic site shells by a layer-by-layer fabrication method. Among all the so-prepared catalysts, P[3SPA-2DABCO]@SiO 2 @Fe 3 O 4 performed extremely well, stabilizing the soybean oil-methanol Pickering emulsion for 24 h. Biodiesel yields of up to 98.2% were achieved after 5 wt.% catalyst dosage at 60 • C for 5 h of reaction.…”

A new heterogeneous K2CO3 supported by a layered double hydroxide (LDH), Mg–Al hydrotalcite, was prepared and used as a catalyst for the biodiesel preparation by a tri‐component coupling transesterification of methanol, vegetable oil, and methyl acetate. K2CO3/Mg‐Al exhibits high catalytic activities, and biodiesel yield can reach 99.48% within 20 min under 60°C, with 6 wt.% of K2CO3/Mg‐Al, 1:1:12 molar ratio of rapeseed oil, methyl acetate, and methanol. Fourier‐transform infrared spectroscopy, X‐ray diffraction (XRD), scanning electron microscopy, nitrogen physical adsorption, thermogravimetry analysis, and CO2‐chemical adsorption were used to assess the physical properties of the prepared K2CO3/Mg‐Al. Using the tri‐component coupling transesterification, 12.2% cost reduce can be get by reducing the cost from 8458 to 7424 ¥/t compared with di‐component transesterification containing oil and methanol as resource.

“…If we consider these carbon-containing wastes as an alternative source of hydrocarbons, then the development of new integrated technologies based on the use of effective catalysts will allow us to fully solve the existing environmental threats in the future. Moreover, it will make it possible to saturate the market with the necessary fuels, products and materials [16][17][18][19][20][21][22][23].…”

Activity features of catalysts for thermocatalytic hydrogenation processing of polymer waste

et al. 2022

The aim of this study was to obtain new catalysts for the processing of carbon-containing polymer waste based on polyethylene and polypropylene, represented mostly by lids from beverages bottled in plastic containers, which accumulate in huge quantities in landfills, by the method of thermocatalytic hydrogenation into liquid fuels and other products. The process was carried out in the presence of fuel oil as a binder, a source of hydrogen and additional hydrocarbons. Thus, two tasks can be solved simultaneously: recycling the polymer waste and obtaining the alternative raw materials from the polymer waste in order to save resources and improve the environmental situation in general. New catalysts based on activated zeolite modified with Mo(VI) and W(VI) salts of various concentrations for the thermocatalytic hydrogenation processing of waste plastics into motor fuels were synthesized. The composition, structure, morphology and adsorption properties of the catalysts were determined by different physicochemical methods. The suitability of the obtained catalysts for use in the thermocatalytic hydrogenation processing of plastic waste into fuels was determined. The catalysts were tested during the processing of a mixture of polyethylene-polypropylene: a paste-forming agent (fuel oil) at T=450 °C and a pressure of 0.6 MPa. The individual and group composition of gasoline, diesel and gas oil fractions was determined by chromatography coupled with mass spectrometry. The maximum yield of the gasoline fraction (16.9 wt.%) and diesel fraction (39.31 wt.%) was obtained on a 2%W(VI)/diatomite catalyst.
