3D ordered meso-macroporous (3DOMM) Ce0.2Zr0.8O2 (CZO) was successfully synthesized by a combined method of evaporation-induced interfacial self-assembly (EISA) and colloidal crystal templates (CCT). The multifunctional catalysts spinel-type PdxCo3–xO4 nanoparticles (NPs) supported on 3DOMM CZO were fabricated gas bubbling assisted coprecipitation (GBCP) method. relationship between nanostructure (hierarchical pore active phase) activity during catalytic soot oxidation studied the techniques...
Cyclohexanols are widely used chemicals, which mainly produced by oxidation of fossil feedstocks. Selective hydrodeoxygenation lignin derivatives has great potential for producing these chemicals but is challenging to obtain high yields. Here, we report that CeO2-supported Ru single-atom catalysts (SACs) enabled the hydrogenation benzene ring and catalyzed etheric C-O(R) bond cleavage without changing C-O(H) bond, could afford 99.9% yields cyclohexanols. As far as know, this first SACs...

The catalytic performances for soot purification over the perovskite-type ABO
Low-temperature and selective reductive amination of carbonyl compounds is a highly promising approach to access primary amines. However, it remains great challenge conduct this attractive route efficiently over earth-abundant metal-based catalysts. Herein, we designed several Co-based catalysts (denoted as Co@C-N(x), where x represents the pyrolysis temperature) by metal-organic framework ZIF-67 at different temperatures. Very interestingly, prepared Co@C-N(800) could catalyze various...
Catalytic conversion of renewable lignin to aromatics can effectively alleviate the fossil resource crisis. Herein, we prepared porous nitrogen-doped carbon-supported cobalt nanoparticle catalyst (CoNC) using a SiO2 template and tested its catalytic performance for cleavage β-O-4 ether bond in model compounds.
