Liquid Nitrogen-Mediated Thermal Shock for Instantaneous Detachment of Multi-walled Carbon Nanotube Films from Substrates and Their Application in Supercapacitors

Paul Joseph Dyson, Zhaofu Fei, Zhangjun Huang, Haiyan Jia

Pristine multiwalled carbon nanotube (MWNT) films have a range of important applications. Currently, vacuum filtration is the main method used to prepare MWNT films, which limits their large-scale production. Solvent evaporation is an alternative method us ...

Depletion Effect-mediated Association of Carbon Nanotube-Polymer Composites and Their Application as Inexpensive Electrode Support Materials

Paul Joseph Dyson, Zhangjun Huang

The association between carbon nanotubes (CNTs) and polymers to afford functional composites has been attributed to enthalpic interactions, neglecting the entropic depletion effect, in which bound solvents are released during the association process. Here, ...

Acceptorless dehydrogenation and hydrogenation of N- and O-containing compounds on Pd3Au1(111) facets

Paul Joseph Dyson, Zhaofu Fei, Antoine Philippe Van Muyden, Tao Wang, Zhangjun Huang, Xinjiang Cui

Catalytic dehydrogenation and hydrogenation of amines and alcohols are important in the synthesis of fine chemicals. Despite several efficient homogeneous catalysts having been identified, highly active heterogeneous catalysts remain elusive, although they ...

Indirect CO2 Methanation: Hydrogenolysis of Cyclic Carbonates Catalyzed by Ru-Modified Zeolite Produces Methane and Diols

Paul Joseph Dyson, Antoine Philippe Van Muyden, Felix Daniel Bobbink, Wei-Tse Lee, Zhangjun Huang

We report a ruthenium‐modified zeolite which efficiently transforms propylene carbonate to propylene glycol and methane, under solvent‐free conditions. The catalyst achieved high product selectivity and no significant ageing effect was observed after multi ...

Leather-Promoted Transformation of Glucose into 5-Hydroxymethylfurfural and Levoglucosenone

Paul Joseph Dyson, Felix Daniel Bobbink, Florent Menoud, Zhangjun Huang

The search for efficient catalysts frequently leads to new homogeneous and heterogeneous catalysts of increasing complexity, and sometimes common, natural, or hybrid natural/synthetic materials that could be used in catalysis are overlooked. For example, t ...

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

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

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 ...

Sustainable, Reshapable Surfactant-Polyelectrolyte Plastics Employing Water as a Plasticizer

Paul Joseph Dyson, Zhaofu Fei, Antoine Philippe Van Muyden, Zhangjun Huang, Haiyan Jia

Natural polymers such as those present in foods contain abundant noncovalent intra- and intermolecular interactions, notably hydrogen bonds, which make them rigid when dry, but on exposure to water soften, due to disruption of these interactions. This soft ...

Ionic liquid containing electron-rich, porous polyphosphazene nanoreactors catalyze the transformation of CO2 to carbonates

Paul Joseph Dyson, Zhaofu Fei, Felix Daniel Bobbink, Yefeng Wang, Zhangjun Huang, Jorge Gustavo Uranga, Haiyan Jia

We show that ionic liquids (ILs) interact with electron-rich, porous polyphosphazene (PPZ), to form hybrid PPZ-IL nanoreactors able to simultaneously capture and transform CO2 into carbonates. The PPZ nanospheres swell in organic solvents and effectively a ...

Are pi-pi Interactions in Ionic Liquids Related to Conductivities?

Rosario Scopelliti, Paul Joseph Dyson, Zhaofu Fei, Farzaneh Fadaei Tirani, Zhangjun Huang

A series of functionalised imidazolium halide salts with substituents able to form pi-bonds have been prepared and characterised. Subsequent reaction of these imidazolium halides with Ag[C(CN)(3)] affords imidazolium-based ionic liquids (ILs), some of whic ...
