Stabilizer-free bismuth nanoparticles for selective polyol electrooxidation.

摘要: Bismuth is the least toxic element among heavy metals, an outstanding advantage for environmental and health considerations. Yet, utilizing bismuth as anodic electrocatalyst hindered by formation of a spreading Bi(OH)3 inhibitor layer during process. Herein, we report that nanoparticles, produced using laser ablation, can avoid such drawbacks. The production Bi(V) species assists polyol electrooxidation. For glucose, instead commonly reported gluconic acid product, enables highly selective oxidation C-C bond cleavage to produce arabinonic acid, erythronic eventually glyceric acid. We not only generate high-valent catalytic applications, especially bioelectrocatalysis where less appreciated, but also present Bi nanoparticle break bond. believe find broader applications in electrochemical biomass conversion electrosynthesis.
