How to be active: The activity of Ni/ZrO₂ catalysts for the dry reforming of methane is enhanced by activation and regeneration of the catalyst in the presence of CO₂. In situ X-ray absorption and FTIR spectroscopy of adsorbed CO show that an increased metal–support interface created during CO₂ treatment opens an additional pathway for CO₂ activation and provides labile oxygen species for carbon removal.

二氧化碳诱导的镍/锆氧化物的金属氧化物界面重整提高甲烷干重整的活性

如何发挥活性：在CO ₂的存在下，催化剂的活化和再生可增强Ni / ZrO ₂催化剂对甲烷干重整的活性。吸附的CO的原位X射线吸收和FTIR光谱表明，在CO ₂处理期间产生的增加的金属-载体界面为CO ₂活化开辟了另一条途径，并为碳去除提供了不稳定的氧。
