Unlike conventional hydrogen production methods, catalytic methane decomposition (CMD) produces hydrogen gas without the production of greenhouse gases. Carbonaceous materials including activated carbon (AC), mesoporous carbon (MC) and carbon black (CB) were investigated as metal-free catalysts for CMD. CB showed greater stability over the course of the reaction than AC and MC. A strong relationship between the number and type of oxygen-containing functional groups and methane conversion was found. In this work, the effect of the type of functional group and the origin of activity as well as the deactivation mechanism are discussed.

无金属碳催化剂中含氧官能团对甲烷分解的影响

与传统的制氢方法不同,催化甲烷分解(CMD)产生的氢气不产生温室气体。研究了含碳材料,包括活性炭(AC),中孔碳(MC)和炭黑(CB),作为CMD的无金属催化剂。CB在反应过程中显示出比AC和MC更高的稳定性。发现含氧官能团的数量和类型与甲烷转化率之间有很强的关系。在这项工作中,讨论了官能团类型和活性来源以及失活机理的影响。
