摘要 我们报导一在基于锌(II ) 播种途径的 situ 快在白轻照耀下面的卟啉(ZnP ) ，与悦耳的尺寸导致一致的球形的铂 nanodendrites。铂 nanodendrites 展览显著地与商业铂黑色相比向氧减小反应(ORR ) 和甲醇氧化反应(粗腐殖质) 改进了 electrocatalytic 活动。 We report a fast in situ seeding approach based on zinc（II） porphyrin （ZnP） under white light irradiation, leading to uniform spherical platinum nanodendrites with tunable sizes. The platinum nanodendrites exhibit significantly improved electrocatalytic activities toward oxygen reduction reaction （ORR） and methanol oxidation reaction （MOR） compared with commercial platinum black.
