Abstract The recent dramatic increase in research on isolated metal atoms has received extensive scientific interest in the new frontier of single‐atom catalysis. As newly advanced materials in catalysis, single‐atom catalysts (SACs) have received enormous interest from the perspectives of both scientific research and industrial applications due to their remarkable activity. In addition, other catalytic properties of single metal atoms, including stability and selectivity, can be further improve
Value-added aromatic monomers such as benzene, toluene, and xylenes (BTX) are very important building-block chemicals for the production of plastics, polymers, solvents, pesticides, dyes, and adhesives. Syngas-to-aromatics (STA) is a very promising approach for the synthesis of aromatic monomers, and is catalyzed via bifunctional catalysts in a single reactor, wherein methanol/dimethyl ether and/or olefins intermediates formed from syngas on metal components are converted into aromatic monomers
The different behaviors of structural promoters such as gallium or zinc oxides on the acidic γ-Al2O3 surfaces were investigated for a direct CO2 hydrogenation to DME by using highly ordered mesoporous bifunctional Cu/Al2O3 (Cu/m-MAl, M = Ga or Zn) to verify their gradual changes of product distribution as well as catalytic stability with time on stream. The oxidation states of Cu nanoparticles with their extent of aggregations and amounts of acidic sites on the mesoporous γ-Al2O3 were significan
The coproduction of methanol (MeOH) and dimethyl ether (DME) from biomass-derived synthesis gas on the coprecipitated Cu−ZnO−Al2O3/γ-Al2O3 hybrid catalysts has been investigated to overcome the equilibrium conversion of CO on the MeOH only synthetic reaction at the H2-decificient condition. Two different types of γ-Al2O3 were employed as the solid-acid component of hybrid catalyst: one prepared by a precipitation method and the other prepared by a sol–gel method. Several hybrid catalysts were pr
Volatile organic compounds (VOCs) are toxic and are considered the most important sources for the formation of photochemical smog, secondary organic aerosols (SOAs), and ozone. These can also greatly affect the environment and human health. For this reason, VOCs are removed by applying various technologies or reused after recovery. Catalytic oxidation for VOCs removal is widely applied in the industry and is regarded as an efficient and economical method compared to other VOCs removal technologi
Recently, air pollution has worsened throughout the world, and as regulations on nitrogen oxides (NOx) are gradually tightened many researchers and industrialists are seeking technologies to cope with them. In order to meet the stringent regulations, research is being actively conducted worldwide to reduce NOx-causing pollution. However, different countries tend to have different research trends because of their regional and industrial environments. In this paper, the results of recent catalyst
