备注

合成气(CO和H2混合气)选择性制备碳氢化合物燃料及化学品是目前最具挑战的催化反应之一.我国拥有丰富的煤炭资源,发展煤经合成气催化转化技术可以减少对石油的依赖,因此相关研究具有十分重要的意义.近年来纳米反应器在合成气选择性转化反应中得到了广泛应用,其优势主要体现在孔道结构可控、表面可功能化、稳定活性金属、反应过程强化等方面.本文基于合成气选择性转化,重点介绍了纳米反应器的构筑以及调控碳氢化合物选择性方面的微观机制的研究进展,为合成气的选择性转化提供研究思路.

Selective synthesis of hydrocarbon fuels and chemicals from syngas(a mixture of carbon monoxide and hydrogen)is one of the most challenging catalytic reactions.Since China has rich reserves of coal,the development of technology of coal catalytic conversion via syngas can reduce the dependence on petroleum.The research on catalytic syngas conversion is thus of great significance.In recent years,nanoreactors have been widely used in the selective conversion of syngas,and its advantages include the controllable pore structure,easy surface functionalization,stabilization of active metals,enhancement of reaction process,etc.Based on the selective conversion of syngas,this review focuses on the construction of nanoreactors and the micro-mechanism in tuning the selectivity of hydrocarbons.Recent research advances are summarized with the aim to provide research ideas on selective conversion of syngas.
