Plasma-Induced Catalyst Support Defects for the Photothermal Methanation of Carbon Dioxide [PDF]

Materials, 2021
The presence of defects in a catalyst support is known to benefit catalytic activity. In this work, a He-plasma treatment-based strategy for introducing and stabilising defects on a Ni/TiO2 catalyst for photothermal CO2 hydrogenation was established. The impact of pretreatment step sequence—which comprised He-plasma treatment and reduction/passivation ...
