MXene (TiCT) and Carbon Nanotube Hybrid-Supported Platinum Catalysts for the High-Performance Oxygen Reduction Reaction in PEMFC.

The metal-support interaction offers electronic, compositional, and geometric effects that could enhance catalytic activity and stability. Herein, a high corrosion resistance and an excellent electrical conductivity MXene (TiCT) hybrid with a carbon nanotube (CNT) composite material is developed as a support for Pt. Such a composite catalyst enhances durability and improved oxygen reduction reaction activity compared to the commercial Pt/C catalyst.

Pd/MXene(TiCT)/reduced graphene oxide hybrid catalyst for methanol electrooxidation.

A key challenge in developing direct methanol fuel cells is the fabrication of electrocatalysts with high activity and long durability. Herein, we report a performance enhanced electrocatalyst of nanoscale Pd on MXene (TiCT) and reduced graphene oxide (rGO). The mass activity of Pd/TiCT-rGO (1: 1) hybrid toward methanol oxidation reaction is 753 mA mg, which is 1.
