Abstract

Activated carbon fibers (ACFs) are a good support for metal catalysts due to their high specific surface area and abundant micropores. In this study, a simple catalyst preparation method was proposed to in-situ load different metal elements on coal pitch-based activated carbon fibers by impregnation and calcination technique using coal pitch-based activated carbon fibers as raw material. Different catalysts showed excellent catalytic activities for the reduction of p-nitrophenol. The results showed that the metal active elements were successfully loaded onto the activated carbon fibers. In addition, the catalyst containing Ni, Co, and Cu metal ions(ACF–3) showed excellent catalytic activity, and the conversion rate reached 95.33% at 1 min. The catalyst was recovered and reused and still showed catalytic performance after five cycles. This indicates that coal pitch-based activated carbon fibers could serve as an efficient support material for a wide range of catalytic applications.

原位负载煤沥青基活性炭纤维的多种金属元素作为对硝基苯酚转化的高效催化剂

活性炭纤维具有高比表面积和丰富的微孔，是金属催化剂的良好载体。本研究提出了一种简单的催化剂制备方法，以煤沥青基活性炭纤维为原料，通过浸渍和煅烧技术在煤沥青基活性炭纤维上原位加载不同的金属元素。不同催化剂对对硝基苯酚的还原表现出优异的催化活性。结果表明，金属活性元素被成功地加载到活性炭纤维上。此外，含Ni、Co、Cu金属离子的催化剂（ACF-3）表现出优异的催化活性，在1 min内转化率达到95.33%。该催化剂经过5次循环回收再利用后仍具有良好的催化性能。这表明煤沥青基活性炭纤维可以作为一种高效的支撑材料，在广泛的催化应用中发挥作用。

期刊介绍： The Journal of Porous Materials is an interdisciplinary and international periodical devoted to all types of porous materials. Its aim is the rapid publication of high quality, peer-reviewed papers focused on the synthesis, processing, characterization and property evaluation of all porous materials. The objective is to establish a unique journal that will serve as a principal means of communication for the growing interdisciplinary field of porous materials. Porous materials include microporous materials with 50 nm pores. Examples of microporous materials are natural and synthetic molecular sieves, cationic and anionic clays, pillared clays, tobermorites, pillared Zr and Ti phosphates, spherosilicates, carbons, porous polymers, xerogels, etc. Mesoporous materials include synthetic molecular sieves, xerogels, aerogels, glasses, glass ceramics, porous polymers, etc.; while macroporous materials include ceramics, glass ceramics, porous polymers, aerogels, cement, etc. The porous materials can be crystalline, semicrystalline or noncrystalline, or combinations thereof. They can also be either organic, inorganic, or their composites. The overall objective of the journal is the establishment of one main forum covering the basic and applied aspects of all porous materials.
