Recent progress in fabricating efficient Ni-based catalysts by cold plasma

Ni-based catalysts have advantages of low cost, rich resource and high catalytic activity. However, Ni-based catalyst has a poor resistance to carbon deposition, and thus can be easily deactivated due to serious carbon deposition. How to improve the resistance of Ni-based catalyst to carbon deposition is a focus of both academia and industry. Cold plasma has been widely used in fabricating coke-resistant Ni-based catalysts, due to its low operation temperature and abundant high-energy species. In the present paper, recent progresses in fabricating coke-resistant Ni-based catalysts by cold plasma are reviewed. The influences of the low operation temperature and high-energy species of cold plasma on the properties of supports, Ni-support interactions and Ni nanoparticles are discussed. The origins for the enhanced carbon deposition resistance of the Ni-based catalysts prepared by cold plasma are analyzed. Finally, we propose that increasing the yield of Ni-based catalysts, decreasing the power consumption and combining cold plasma with other techniques like artificial intelligence are the main research directions in the field of preparing coke-resistant Ni-based catalysts by cold plasma.
