Abstract

A new catalytic approach is pioneered to achieve CO methanation a single atom alloy Ir/Ni catalyst using a ball-milling method. This Ir/Ni catalyst exhibits a TOF of 10244 h and a 220 h lifetime at 350 °C without deactivation, illustrating excellent catalytic efficiency in the presence of mechanical energy.

摘要

一种新的催化方法被开创，以实现 CO 甲烷化——使用球磨法制备 Ir/Ni 单原子合金催化剂。该 Ir/Ni 催化剂在 350°C 下具有 10244 h 的 TOF 和 220 h 的寿命，没有失活，在机械能存在下表现出优异的催化效率。
