XENLUO.XYZ reported on February 14 that hydrogen energy, as an important clean energy source, is widely regarded as an important pillar of the global energy system in the future. Professor Martin’s team and collaborators at Peking University focus on hydrogen production technology.Two research results were published on Nature and Science on February 13 and 14 respectively。

The research team published in the journal Nature entitled “Shielding Pt/γ-Mo”2N by Inert Nano-overlays Enables Stable H2 Production” focuses on catalyst stability, continues Professor Martin’s previous research on hydrogen production by methanol and water reforming, and innovatively introduces rare earth elements to transform the catalyst.A new and widely used stabilization strategy for high-active hydrogen production catalysts has been developed.
The study found that when rare earth elements exist on the catalyst surface and protect the “non-interface active site” of the catalyst, the life of the catalyst is greatly improved. Specifically, each Pt atom in the catalyst can generate 15 million hydrogen molecules, this “conversion number”It exceeded the highest record previously reported by an order of magnitude.This historic breakthrough provides a new idea for efficient and stable hydrogen production technology.
The research team published in Science magazine entitled “Thermal catalytic reforming for hydrogen production with zero CO2 The research results of emission” focus on the zero-carbon emission hydrogen production path of ethanol and water molecules reforming.
The team developed an efficient Pt-Ir/α-MoC interface catalyst, which not only achieved the simultaneous activation of water molecules and ethanol molecules, but also successfully avoided the breakage of CC bonds of ethanol molecules. This means thatIn addition to the target product hydrogen, the reaction can also produce high added value acetic acid, while the entire process achieves zero CO2 emissions. This major achievement has laid a solid scientific foundation for industrial hydrogen production with zero carbon emissions.
The two achievements form technical complementarity: Rare earth modified catalysts significantly improve the efficiency and service life of hydrogen production, providing the possibility for large-scale industrial production of hydrogen; zero CO2 Emission of hydrogen production-coproduction chemical technology has created a new green chemical path, which not only reduces carbon emissions, but also achieves efficient utilization of resources.
