Latest Patents

Zhe Li's latest patents demonstrate groundbreaking advancements in catalytic technology. The first patent focuses on "Transition metal carbides for catalytic methane activation," which introduces a novel MXene support that forms a catalyst with active sites comprising single metal-layer nanostructures. This catalyst is notable for its stability during methane conversion to higher hydrocarbons while effectively reducing coke formation. The experimental results indicate that platinum atoms can form multiple layers on the surface of the MoTiCT support when reduced at 750°C. This innovation enhances the selectivity for C-hydrocarbons and facilitates a cost-effective conversion of methane into more valuable products.

His second patent highlights the development of a "Two-dimensional metal carbide catalyst." This research reports the first example of a reactive metal support interaction (RMSI) between platinum and various MXenes, which are two-dimensional metal carbides, nitrides, or carbonitrides. The invention encompasses intermetallic Pt/MXene nanoparticle catalysts, featuring unique platinum and MXene elements. By utilizing RMSI, Pt nanoparticles were successfully supported on TiC and NbC MXenes, confirming the intermetallic structures through rigorous analytical methods such as X-ray Absorption Spectroscopy (XAS), Atomic Resolution Scanning Transmission Electron Microscopy (ARSTEM), and X-ray Photoelectron Spectroscopy (XPS). Additionally, the findings revealed that the alloy formation is temperature-dependent, promoting enhanced catalytic properties, such as improved selectivity and stability for alkane dehydrogenation over traditional platinum catalysts.
