Summary: The energy crisis in today's society has led to research interest in alternative energy sources. Methanol oxidation is a potential energy source but requires an efficient electrocatalyst such as Pt. The practicality of Pt is hindered by its high cost and poisoning effect. Therefore, there is a need for an efficient catalyst for methanol oxidation. In this study, nanobelt Cu3Se2/Cu1.8Se catalysts were synthesized using high temperature, pressure, and diethylenetriamine (DETA) as a reaction medium/structure directing agent. The catalyst showed optimized methanol electrooxidation reaction (MOR) response and exhibited high electrochemical active surface area (ECSA) and good stability, leading to high MOR performance. The unique 2D hexagonal nanobelt morphology of the catalyst provided a large surface area for the reaction, reducing diffusion kinetics and increasing reaction sites.

Summary: In this work, a simple two-step electrodeposition strategy was developed to fabricate morphology-controlled gold microspheres (AuMS) decorated polydiphenylamine (PDPA) nanohybrid modified FTO electrode. The PDPA/AuMS modified electrode was characterized using XRD and SEM/EDX mapping techniques. The as-fabricated PDPA/AuMS modified FTO electrode showed excellent electrocatalytic activity for methanol oxidation reaction (MOR) and exhibited extended stability and durability. Based on the results, the PDPA/AuMS nanohybrid composite can be applied as a potential electrocatalyst/alternative electrode for direct methanol fuel cell (DMFC) applications.

Summary: In this study, graphene nanoplates (GNPs) coated with sulfated zirconium dioxide (ZrO2) were used as support for platinum (Pt) catalysts in direct ethanol fuel cells (DEFCs). The Pt/S-ZrO2-GNP electrocatalyst showed higher electrocatalytic activity and carbon monoxide (CO) tolerance compared to unsulfated counterparts. The new material also exhibited increased ethanol oxidation activity and reaction kinetics. The study suggests that sulfonating is a practical approach for improving the performance of electrocatalysts in DEFCs.

Summary: In this study, CeO2 is modified through a plasma-phosphating combing strategy and invited as Frustrated Lewis Pair to assist the catalytic MOR process on Pt sites. This strategy also leads to negatively charged sites on CeO2 surface as a host for Pt anchoring, facilitating the even dispersion of Pt nanocrystals. Moreover, this strategy affects the Ce3+/Ce4+ ratio and vacancy oxygen ratio on CeO2 surface, which are critical for OH generation and anti-CO.

Summary: Size-selected 3 nm gas-phase Au clusters deposited via cluster beam deposition on a conducting fluorine-doped tin oxide template exhibit a strong enhancement in mass activity for the methanol electro-oxidation reaction compared to previously reported nanostructured gold electrodes. The high MEO activity is attributed to the high density of exposed under-coordinated Au atoms on their faceted surface, with vertices and edges being the most active sites due to their favorable CO and OH adsorption energies. The faceted structures in this size range, partly retained during deposition, may also protect against destructive restructuring during the oxidation-reduction cycle.

Summary: Developing high-performance electrocatalysts is crucial for efficient methanol electro-reforming. In this study, a NiCoMo alloy pre-catalyst with nanosheets covered nanowires arrays is proposed, which undergoes surface reconstruction and forms a Mo substituted NiCoOOH layer as the real catalyst. The surface engineered catalysts exhibit high activity and stability, achieving efficient co-production of hydrogen and formate. The incorporation of Mo plays multiple roles in stabilizing the structure, promoting surface reconstruction, modulating electronic structure, and boosting catalytic activity.
