Tuning surface composition of multiwalled carbon nanotubes supported Pt-Co bimetallic nanoparticles for boosting methanol oxidation catalysis

Zhengcheng Wang et al.

Summary: In this study, PtCo alloys catalysts supported on multiwalled carbon nanotubes (MWCNTs) were prepared with improved methanol oxidation reaction (MOR) properties and anti-CO poisoning ability. The Pt1Co3@NC/MWCNTs sample with moderate Co2+ feeding content showed a 1.93-fold enhancement in MOR mass activity compared to commercial Pt/C catalyst. Additionally, it displayed a lower CO oxidation onset potential. The improvements in MOR activity, durability, and anti-CO poisoning ability were attributed to the moderate surface compositions, optimal electronic interaction, and the protection of N-doped carbon (NC) shells. This study provides a new direction for the design and fabrication of highly efficient electrocatalysts for DMFCs applications.

Progress and major BARRIERS of nanocatalyst development in direct methanol fuel cell: A review

Zatil Amali Che Ramli et al.

Summary: Direct methanol fuel cells (DMFC) are promising alternatives for portable electronics, and recent research has focused on using nanotechnology to improve their performance. However, slow reaction kinetics limit the efficiency and energy output of DMFC. Platinum and ruthenium are widely explored catalysts in DMFC, and their performance can be enhanced by using supporting materials such as nanocarbons and metal oxides. This research emphasizes the structure of nanocatalysts and the support materials used, and also highlights the cost estimation of fuel cell technology. Future challenges and recommendations for innovative research in nanocatalyst development are discussed.

A single-Pt-atom-on-Ru-nanoparticle electrocatalyst for CO-resilient methanol oxidation

Agus R. Poerwoprajitno et al.

Summary: Single Pt atom catalysts with high exposure are key targets to enhance electrocatalytic activity, and PtRu alloy nanoparticles are the most active catalysts for the methanol oxidation reaction. This study demonstrates a process to create single-Pt-atom-on-Ru catalysts by growing and spreading Pt islands on Ru branched nanoparticles. The formation of a stable single atom structure is driven by the formation of strong Pt-Ru bonds and the lowering of the surface energy of the Pt islands, resulting in a high current density and mass activity for the methanol oxidation reaction over time.
