From: Single-atomic platinum on fullerene C60 surfaces for accelerated alkaline hydrogen evolution
The toluene solution of Pt(dba)2 and C60 (molar ratio: n (C60): n (Pt(dba)2) = 1:1, 2:1, and 4:1, respectively) was stirred at room temperature under nitrogen, in which the dba ligands were completely substituted by C60, forming a platinum-C60 polymeric structure. The increased input of C60 is to better disperse the Pt during the synthesis process and prevent the aggregation of Pt, and any excess C60 was washed off after the reaction.
