Heterogeneous catalysts with precise surface and interface structures are of great interest to decipher the structure-property relationships maintain remarkable stability while achieving high activity. Here, we report design fabrication new sandwich composites ZIF-8@Au25@ZIF-67[tkn] ZIF-8@Au25@ZIF-8[tkn] [tkn = thickness shell] by coordination-assisted self-assembly well-defined interfaces. The ZIF-8@Au25@ZIF-67 efficiently catalyzed both 4-nitrophenol reduction terminal alkyne carboxylation CO2 under ambient conditions remarkably improved activity stability, compared simple components Au25/ZIF-8 Au25@ZIF-8, highlighting highly useful function ultrathin shell. In addition, performances these composite conveniently regulated shell thickness. This concept achievements should open a avenue targeted nanocatalysts enhanced activities stabilities for challenging reactions.

The Use of Heterogeneous Catalysis in the Chemical Valorization of Plastic Waste

ChemSusChem, Год журнала: 2020, Номер 13(22), С. 5808 - 5836

Опубликована: Сен. 30, 2020

Plastic solid waste (PSW) is an ever-growing environmental challenge for our society, as it not only ends up in landfills but also waterways and oceans consequently entering the food chain. A key strategy to overcome this problem while preserving carbon resources use PSW a feedstock, evolving towards circular economy. To implement this, mechanical well chemical recycling technologies must be developed. Indeed, owing high volume of generated each year, alone adequate addressing global challenge. Because via thermal heterogeneous catalytic conversion has received growing attention. This process potential take convert into usable monomers, fuels, synthesis gas, adsorbents under more sustainable conditions than degradation. Review highlights recent research advances valorization.

Hydrothermal Treatment of Biomass Feedstocks for Sustainable Production of Chemicals, Fuels, and Materials: Progress and Perspectives

Chemical Reviews, Год журнала: 2023, Номер 123(11), С. 7193 - 7294

Опубликована: Май 9, 2023

Hydrothermal process is an emerging technology that contributes to sustainable production of biomass-derived chemicals, fuels, and materials. This uses hot compressed water convert various biomass feedstocks including recalcitrant organic compounds in biowastes into desired solid, liquid, gaseous products. In recent years, considerable progress has been made the hydrothermal conversion lignocellulosic as well nonlignocellulosic value-added products bioenergy fulfill principles circular economy. However, it important assess processes terms their capabilities limitations from different sustainability aspects so further advances can be toward improvement technical maturity commercialization potential. The key aims this comprehensive review are (a) explain inherent properties physio-chemical characteristics bioproducts, (b) elucidate related transformation pathways, (c) clarify role for conversion, (d) evaluate capability treatment coupled with other technologies producing novel fuels materials, (e) explore assessments potential large-scale applications, (f) offer our perspectives facilitate transition a primarily petro-based alternative biobased society context changing climate.

Chemicals from Lignin: A Review of Catalytic Conversion Involving Hydrogen

ChemSusChem, Год журнала: 2019, Номер 13(17), С. 4181 - 4198

Опубликована: Дек. 30, 2019

Lignin is the most abundant biopolymer with aromatic building blocks and its valorization to sustainable chemicals fuels has extremely great potential reduce excessive dependence on fossil resources, although such conversions remain challenging. The purpose of this Review present an insight into catalytic conversion lignin involving hydrogen, including reductive depolymerization hydrodeoxygenation lignin-derived monomers arenes, cycloalkanes phenols, a main focus catalyst systems reaction mechanisms. roles hydrogenation sites (Ru, Pt, Pd, Rh) acid (Nb, Ti, Mo), as well their interaction in selective reactions are emphasized. Furthermore, some inspirational strategies for production other value-added mentioned. Finally, personal perspectives provided highlight opportunities within attractive field.
