In this report, Pt/NCNFs/Cu-foil, an efficient and stable catalyst, was prepared by the electrospinning method, which could be directly used for electrochemical reduction of CO2. Formate with 93% Faradaic efficiency and about 46 mA cm−2 partial current density could be obtained at −0.6 VRHE; alcohols with approximately 35% Faradaic efficiency and 14 mA cm−2 partial current density were achieved at −1.0 VRHE using the same Pt/NCNFs/Cu-foil cathode. Moreover, Pt/NCNFs/Cu-foil could keep high efficiencies for at least 50 h durability tests.

无粘结剂的铂/氮掺杂碳纳米纤维/铜箔催化剂选择性电化学还原CO 2,具有出色的效率和可重复使用性

在本报告中,通过电纺丝法制备了高效稳定的Pt / NCNFs / Cu箔,可直接用于电化学还原CO 2。在-0.6 V RHE时可获得法拉第效率为93%的甲酸盐,部分电流密度约为46 mA cm -2;使用相同的Pt / NCNFs / Cu箔阴极,在-1.0 V RHE时可获得法拉第效率约为35%的醇和14 mA cm -2的部分电流密度。此外,Pt / NCNFs / Cu箔可以在至少50小时的耐用性测试中保持较高的效率。
