Summary: In this study, palladium is proposed as an active site for formic acid dehydrogenation reaction, and its activity is modulated with Co metal to achieve efficient hydrogen production for a low noble metal content. The optimization of metal loadings and considerations of reaction temperature and additives were explored for monometallic catalysts. The study aimed to identify routes for reducing noble metal loading towards a more sustainable approach to hydrogen production from liquid organic carrier molecules like formic acid.

Summary: Pd-Pt bimetallic catalysts with dendritic morphology were synthesized on a carbon paper surface using a two-step electrochemical method. These catalysts exhibited enhanced catalytic activity and current density in acidic media, which can be attributed to the atomic defects at the dendrite edges and the high utilization of active sites achieved by the clean electrochemical preparation method.

Summary: Bimetallic Pd-Ag alloy nanoparticles have been found to enhance the performance of H-2 sensors. However, the long-term stability of the sensors with Pd-Ag nanoparticles as catalysts decreases significantly during operation. In this study, gas-cell in situ transmission electron microscopy (TEM) was used to investigate the failure mechanisms of Pd-Ag nanoparticles under operation conditions. Based on the results, two failure mechanisms were identified, and the H-2 sensor was comprehensively optimized to improve stability. The optimized sensor exhibited satisfactory H-2-sensing properties and negligible response decline after 1 month.
