Atomically dispersed Fe3+ sites catalyze efficient CO2 electroreduction to CO

Xile Hu, Lichen Bai, Jun Gu

Currently, the most active electrocatalysts for the conversion of CO2 to CO are gold-based nanomaterials, whereas non-precious metal catalysts have shown low to modest activity. Here, we report a catalyst of dispersed single-atom iron sites that produces C ...

Metal-Sulfide Catalysts Derived from Lignosulfonate and their Efficient Use in Hydrogenolysis

Paul Joseph Dyson, Xile Hu, Zhaofu Fei, Antoine Philippe Van Muyden, Lichen Bai, Xiang Li, Xinjiang Cui, Sijie Liu

Catalytic lignosulfonate valorization is hampered by the in situ liberation of sulfur that ultimately poisons the catalyst. To overcome this limitation, metal sulfide catalysts were developed that are able to cleave the C-O bonds of lignosulfonate and are ...

Oxidative cleavage of -O-4 bonds in lignin model compounds with a single-atom Co catalyst

Paul Joseph Dyson, Xile Hu, Zhaofu Fei, Antoine Philippe Van Muyden, Lichen Bai, Xiang Li, Zhangjun Huang, Xinjiang Cui, Sijie Liu

Single-atom catalysts are emerging as primary catalysts for many reactions due to their 100% utilization of active metal centers leading to high catalytic efficiencies. Herein, we report the use of a single-atom Co catalyst for the oxidative cleavage of th ...

Alkene hydrosilylation catalyzed by easily assembled Ni(II)-carboxylate MOFs

Xile Hu, Lichen Bai, Zhikun Zhang

We report the first Ni MOF catalysts for anti-Markovnikov hydrosilylation of alkenes. These catalysts are bench-stable and easily-assembled from simple Ni salts and carboxylic acids. The best catalyst gives turnover numbers up to 9500 and is robust even af ...

A Cobalt-Iron Double-Atom Catalyst for the Oxygen Evolution Reaction

Xile Hu, Duncan Thomas Lindsay Alexander, Lichen Bai

Single-atom catalysts exhibit well-defined active sites and potentially maximum atomic efficiency. However, they are unsuitable for reactions that benefit from bimetallic promotion such as the oxygen evolution reaction (OER) in an alkaline medium. Here we ...

Transition Metal Oxides as Electrocatalysts for the Oxygen Evolution Reaction in Alkaline Solutions: An Application-Inspired Renaissance

Xile Hu, Fang Song, Lichen Bai, Laurent Liardet, Seunghwa Lee, Aliki Moysiadou, Chao Hu

Water splitting is the essential chemical reaction to enable the storage of intermittent energies such as solar and wind in the form of hydrogen fuel. The oxygen evolution reaction (OER) is often considered as the bottleneck in water splitting. Though meta ...

Towards artificial methanogenesis: biosynthesis of the [Fe]-hydrogenase cofactor and characterization of the semisynthetic hydrogenase

Xile Hu, Tao Xu, Lichen Bai

The greenhouse gas and energy carrier methane is produced on Earth mainly by methanogenic archaea. In the hydrogenotrophic methanogenic pathway the reduction of one CO2 to one methane molecule requires four molecules of H-2 containing eight electrons. Four ...

A Water-Bridged H-Bonding Network Contributes to the Catalysis of the SAM-Dependent C-Methyltransferase HcgC

Xile Hu, Tao Xu, Lichen Bai

[Fe]-hydrogenase hosts an iron-guanylylpyridinol (FeGP) cofactor. The FeGP cofactor contains a pyridinol ring substituted with GMP, two methyl groups, and an acylmethyl group. HcgC, an enzyme involved in FeGP biosynthesis, catalyzes methyl transfer from S- ...

Identification of HcgC as a SAM-Dependent Pyridinol Methyltransferase in [Fe]-Hydrogenase Cofactor Biosynthesis

Xile Hu, Tao Xu, Lichen Bai

Previous retrosynthetic and isotope-labeling studies have indicated that biosynthesis of the iron guanylylpyridinol (FeGP) cofactor of [Fe]-hydrogenase requires a methyltransferase. This hypothetical enzyme covalently attaches the methyl group at the 3-pos ...
