Polyethyleneimine modified AuPd@PdAu alloy nanocrystals as advanced electrocatalysts towards the oxygen reduction reaction

Current status, opportunities, and challenges in fuel cell catalytic application of aerogels

“…In fuel cell, ORR is very important half‐reaction that can be an indicator of single cell performance and operational life of fuel cell system . Xue et al produced N‐GA in different temperature (800°C, 900°C, and 1000°C).…”

“…In fuel cell, ORR is very important half-reaction that can be an indicator of single cell performance and operational life of fuel cell system. 111,112 Xue et al 106 produced N-GA in different temperature (800°C, 900°C, and 1000°C). The best ORR activity was shown by N-GA-150 synthesized at 900°C with onset reduction potential (E onset ) at i = 0.1 mA cm −2 and limiting diffusion current value at 0.6 V as presented in Figure 13.…”

Heat treatment bimetallic PdAu nanocatalyst for oxygen reduction reaction

“…The cathode catalysts react with the infiltrated methanol to cause a mixed potential, which lowers the output voltage of the battery, thereby reducing the activity of the battery. In addition, methanol permeation can also cause poisoning of the cathode catalyst [10][11][12] . Pd has similar crystal structure to Pt, also exhibits certain ORR performance, and has lower price.…”

Rh-doped PdAg nanoparticles as efficient methanol tolerance electrocatalytic materials for oxygen reduction

“…Palladium (Pd), as one of the promising alternative to Pt [39], has been explored by modifying their electronic and geometric structures for both the anode and cathode of DMFCs due to its relative good catalytic performance [40][41][42][43][44][45][46][47][48]. However, for the reported Pd-based materials, it is still very difficult to simultaneously satisfy the following three key features for DMFCs: excellent ORR activity, good methanol tolerance and excellent durability.…”
