The effect of acid treatment in mixed MnOx–CeO2 samples has been investigated the catalytic total oxidation formaldehyde. no on textural and redox properties materials when Mn is stabilized a solid solution (Mn content below 50%). However, these were found to be highly altered by solubility limit ceria was exceeded above This enabled access primary porosity oxidized manganese species higher state via dismutation reaction. As result, activity pure oxide, after chemical activation,...
Methanol-to-hydrocarbons (MTH) process has been considered one of the most practical approaches for producing value-added products from methanol. However, commonly used zeolite catalysts suffer rapid deactivation due to coke deposition and require regular regeneration treatments. We demonstrate that low-melting-point metals, such as Ga, can effectively promote more stable methanol conversion in MTH by slowing facilitating desorption carbonaceous species zeolite. The ZSM-5 physically mixed...
Ru embedded in carbon nitride is prepared by pyrolysis of a COF with coordinated II for highly efficient HER and OER.
We solve the structure of visible light water-splitting photocatalyst α-LaOInS<sub>2</sub> and investigate its properties. This remarkable oxysulfide represents second polymorph in this composition exhibits scarce mixed anion InS<sub>5</sub>O polyhedra.
Activated cobalt metal salts are effective and versatile catalysts for the chemoselective reduction of esters to aldehydes or alcohols through hydrosilylation reaction.
Within conventional bifunctional catalysts, active metal sites are associated with components, while acid usually localized over oxide supports. The modification of by halogens provides an opportunity to generate acidity via the heterolytic dissociation hydrogen directly sites. Herein, we report results high-throughput screening combinations different metals (Co, Ni, Ru, Pt, Pd, Rh) and (Cl, Br, I) for site generation from in hydrogenation furfural 5-hydroxymethylfurfural. demonstrate that...
Acrolein is the simplest unsaturated aldehyde, which – due to its high reactivity has found application as an intermediate in chemical industry.

Abstract This study investigates thermal aging induced effects on the surface properties of model and commercial automotive catalysts for Natural Gas Vehicles, by means X‐ray photoelectron spectroscopy infrared chemisorbed CO as a probe molecule noble metals. Post‐combustion this application are essentially composed palladium containing low amounts rhodium additives to improve oxygen storage properties. The procedure involved exposing an oxidizing atmosphere air 10 vol.% H 2 O at 980 °C 4 h...
Bimetallic layered double oxide (LDO) NiM (M = Cr, Fe) catalysts with nominal compositions of Ni/M 2 or 3 were tailored from hydroxides (LDH) using a coprecipitation method to investigate the effects trivalent metal (Cr and amount Ni species on structural, textural, reducibility, catalytic properties for CH4/CO2 reforming. The solids before after thermal treatment at 500 °C characterized TGA-TD-SM, HT-XRD, XRD, Raman, IR-ATR spectroscopies; N2 physical adsorption; XPS; H2-TPR. According XRD...
Abstract This study reports surface characterizations of Pd/LaFeO 3 catalysts after aging in diesel engine simulated conditions. Thermal and support‐induced effects on the nature Pd species were investigated. LaFeO was prepared via a sol–gel method to promote relatively high specific area (19 m 2 g −1 ). Subsequent impregnation from solutions using Pd(NO ) , Pd(acac) or Pd(NH 4 (NO precursor salts examined by means XPS infrared spectroscopy pre‐activated under reductive atmosphere aged ones...
