Hierarchical monolithic carbon with high transfer performance for hydrogen evolution reaction
文献摘要：
Electrocatalysis is an efficient green process for energy conversion.However,for gas-related electrocat-alytic reaction,sluggish gas transport has inhibited significantly the promotion of electrocatalytic perfor-mances.Herein,hierarchical monolithic material 3DPC-650 and 3DPC-650@Ni/Ni(OH)2 were prepared by 3D printing polyethyleneimine cross-linking oxygenated carbon nanotube and following nickel elec-trodeposition.3DPC-650 and 3DPC-650@Ni/Ni(OH)2 have regular pore structure in consistence with 3D printing design and uniform dispersed elements.Amide bonds and carbon defects are presented on the surface of 3DPC-650 and 3DPC-650@Ni/Ni(OH)2 as well as uniformly distributed p-Ni(OH)2 on 3DPC-650@Ni/Ni(OH)2.3DPC-650 and 3DPC-650@Ni/Ni(OH)2 present lower overpotentials of 322 and 160 mV for hydrogen evolution reaction in 1.0 M KOH at 50 mA cm-2,respectively.The ordered channel,high turnover frequency and electrochemically active surface area,hydrophilic and aerophobic properties result in the higher performance of 3DPC-650 and 3DPC-650@Ni/Ni(OH)2 than traditional supports(car-bon paper,carbon cloth,and nickel foam)and electrocatalysts.This work provides an efficient pathway for design and preparation of the monolithic electrocatalyst and electrode used for electrochemical reac-tions where gas is involved.
