Lignin First: Confirming the Role of the Metal Catalyst in Reductive Fractionation
Paul Joseph Dyson, Gabor Laurenczy, Zhaofu Fei, Antoine Philippe Van Muyden, Lu Chen, Ning Yan, Xinjiang Cui
Rhodium nanoparticles embedded on the interior of hollow porous carbon nanospheres, able to sieve monomers from polymers, were used to confirm the precise role of metal catalysts in the reductive catalytic fractionation of lignin. The study provides clear ...
AMER CHEMICAL SOC2021Discovery of a Highly Active Catalyst for Hydrogenolysis of C-O Bonds via Systematic, Multi-metallic Catalyst Screening
Paul Joseph Dyson, Antoine Philippe Van Muyden, Ning Yan, Sviatlana Siankevich
Hydrogenolysis of C-O bonds is a highly challenging reaction with the most efficient catalysts based on bimetallic assemblies. Systematic studies to identify the optimum metal combination have not been performed and, therefore, we designed a method to scre ...
2019Catalytic amino acid production from biomass-derived intermediates
Paul Joseph Dyson, Ning Yan, Yefeng Wang, Shunlin Zhang, Yu Han
Amino acids are the building blocks for protein biosynthesis and find use in myriad industrial applications including in food for humans, in animal feed, and as precursors for bio-based plastics, among others. However, the development of efficient chemical ...
National Academy of Sciences2018Influence of the Anion on the Oxidation of 5-Hydroxy-methylfurfural by Using Ionic-Polymer-Supported Platinum Nanoparticle Catalysts
Paul Joseph Dyson, Zhaofu Fei, Felix Daniel Bobbink, Ning Yan, Sviatlana Siankevich, Simone Mozzettini
Platinum nanoparticles stabilized by an imidazolium-based cross-linked polymer (with chloride as the counteranion) efficiently catalyzed the oxidation of 5-hydroxymethylfurfural to form 2,5-furandicarboxylic acid in water under mild conditions with oxygen ...
2018Single-step conversion of lignin monomers to phenol: Bridging the gap between lignin and high-value chemicals
Transformation of lignin into high-value chemicals is hampered by the complexity of monomers obtained from lignin depolymerization. Here we report a strategy, composed of hydro-demethoxylation and de-alkylation reactions, that is able to chemically converg ...
2018Efficient cleavage of aryl ether C–O linkages by Rh–Ni and Ru–Ni nanoscale catalysts operating in water
Paul Joseph Dyson, Vassily Hatzimanikatis, Duncan Thomas Lindsay Alexander, Antoine Philippe Van Muyden, Ning Yan, Georgios Savoglidis, Sviatlana Siankevich, Safak Bulut
Bimetallic Ru–Ni and Rh–Ni nanocatalysts coated with a phase transfer agent efficiently cleave aryl ether C–O linkages in water in the presence of hydrogen. For dimeric substrates with weaker C–O linkages, i.e. α-O-4 and β-O-4 bonds, low loadings of the pr ...
2018A rational synthesis of hierarchically porous, N-doped carbon from Mg-based MOFs: understanding the link between nitrogen content and oxygen reduction electrocatalysis
Controlled mixtures of novel Mg-based metal-organic frameworks (MOFs) were prepared, with H+ or K+ as counterions. A linear relation was found between synthesis pH and K/H ratio in the resultant mixture, establishing the tunability of the synthesis. Upon p ...
Royal Soc Chemistry2016Cold pulse and rotation reversals with turbulence spreading and residual stress
Transport modeling based on inclusion of turbulence spreading and residual stresses shows internal rotation reversals and polarity reversal of cold pulses, with a clear indication of nonlocal transport effects due to fast spreading in the turbulence intens ...
American Institute of Physics2016Direct Conversion of Mono- and Polysaccharides into 5-Hydroxymethylfurfural Using Ionic-Liquid Mixtures
Paul Joseph Dyson, Rosario Scopelliti, Zhaofu Fei, Ning Yan, Sviatlana Siankevich, Philip Gregory Jessop
Platform chemicals are usually derived from petrochemical feedstocks. A sustainable alternative commences with lignocellulosic biomass, a renewable feedstock, but one that is highly challenging to process. Ionic liquids (ILs) are able to solubilize biomass ...
Wiley-VCH Verlag Berlin2016Conversion of chitin derived N-acetyl-D-glucosamine (NAG) into polyols over transition metal catalysts and hydrogen in water
Felix Daniel Bobbink, Ning Yan, Xi Chen
N-Acetyl-D-glucosamine (NAG), the monomer of the world's second most abundant biopolymer chitin, has been for the first time converted to its corresponding amide/amino substituted sugar alcohols, smaller C2-4 polyols and N-acetylmonoethanolamine (NMEA), ov ...
