摘要:

Ni基催化剂价格低廉、资源丰富、活性出色,但其抗积炭能力差、易因严重积炭而失活的问题始终是限制其应用的瓶颈,如何提升Ni基催化剂抗积炭能力是学术界和工业界极为关注的问题。低温等离子体因宏观低温、粒子高能的特点而被广泛用于构筑高抗积炭Ni基催化剂。本文介绍了低温等离子体构筑高效Ni基催化剂领域的最新进展,讨论了低温等离子体较低的宏观温度和丰富的高能粒子对载体性质、Ni-载体作用和Ni颗粒特性的影响,分析了低温等离子体所构筑Ni基催化剂具有优异抗积炭能力的原因,提出增加Ni基催化剂制备量、降低低温等离子体耗电量和将低温等离子体与人工智能等技术结合是未来低温等离子体构筑Ni基催化剂领域的主要研究方向。

Abstract:

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.

Key words: catalyst, carbon deposition, cold plasma, support, interface, nickel
