Summary
This study introduces a novel MXene-supported platinum nanocluster catalyst for efficient and stable hydrogen production via electrolysis. The new catalyst significantly reduces platinum use while maintaining high performance, challenging current electrolyzer designs.
Area of Science:
- Materials Science
- Electrochemistry
- Catalysis
Background:
- Proton exchange membrane water electrolysis is key for sustainable hydrogen production.
- Reducing platinum (Pt) usage in catalysts is crucial for economic viability.
- Enhancing Pt intrinsic activity and catalyst stability are major challenges.
Purpose of the Study:
- To develop a highly active and stable Pt catalyst with minimal Pt loading for water electrolysis.
- To investigate the charge transfer mechanisms between the support and Pt nanoclusters.
- To evaluate the performance of the novel catalyst in a proton exchange membrane electrolyzer.
Main Methods:
- Synthesis of Mo2TiC2 MXene-supported Pt nanocluster catalyst (Mo2TiC2-PtNC).
- Operando spectroscopy and theoretical simulations to study charge transfer.
- Performance testing in a proton exchange membrane electrolyzer at 200 mA cm-2.
Main Results:
- Mo2TiC2-PtNC catalyst achieves high activity and stability with minimal Pt loading (36 μg cm-2).
- Anomalous charge transfer from MXene to PtNC creates electron-rich Pt sites, enhancing hydrogen evolution.
- Electrolyzer testing showed over 8700 hours of operation with a low decay rate (2.2 μV h-1).
Conclusions:
- The Mo2TiC2-PtNC catalyst offers superior performance compared to conventional high-loading Pt/C catalysts.
- This development presents a viable alternative for reducing Pt reliance in electrolyzer technology.
- The findings pave the way for more cost-effective sustainable hydrogen production.

02:13Reduction of Alkenes: Catalytic Hydrogenation
11.7K
Alkenes undergo reduction by the addition of molecular hydrogen to give alkanes. Because the process generally occurs in the presence of a transition-metal catalyst, the reaction is called catalytic hydrogenation.
Metals like palladium, platinum, and nickel are commonly used in their solid forms — fine powder on an inert surface. As these catalysts remain insoluble in the reaction mixture, they are referred to as heterogeneous catalysts.

02:17Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
3.2K
Catalytic hydrogenation of alkenes is a transition-metal catalyzed reduction of the double bond using molecular hydrogen to give alkanes. The mode of hydrogen addition follows syn stereochemistry.
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

02:24Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation

Introduction
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
