Highly Loaded Independent Pt⁰ Atoms on Graphdiyne for pH-General Methanol Oxidation Reaction.

ABSTRACT: The emergence of platinum-based catalysts promotes efficient methanol oxidation reactions (MOR). However, the defects of such noble metal catalysts are high cost, easy poisoning, and limited commercial applications. The efficient utilization of a low-cost, anti-poisoning catalyst has been expected. Here, it is skillfully used N-doped graphdiyne (NGDY) to prepare a zero-valent platinum atomic catalyst (Pt/NGDY), which shows excellent activity, high pH adaptability, and high CO tolerance for MOR. The Pt/NGDY electrocatalysts for MOR with specific activity 154.2 mA cm^-2 (1449.3 mA mg_Pt ^-1 ), 29 mA cm^-2 (296 mA mg_Pt ^-1 ) and 22 mA cm^-2 (110 mA mg_Pt ^-1 ) in alkaline, acid, and neutral solutions.
