不同硫源水热合成的MoS2催化剂的形貌和加氢脱氧活性比较研究
A comparison of MoS2catalysts hydrothermally synthesized from different sulfur precursors in their morphology and hydrodeoxygenation activity
摘要
Abstract
Three MoS2catalysts were synthesized by a hydrothermal method using different sulfur precursors such as thiourea, L-cystine and sulfur powder;their differences in the structure,morphology,and catalytic activity in the hydrodeoxygenation (HDO) of p-cresol were comparatively investigated. The results illustrated that the sulfur source has a significant influence on the morphology and surface area of the as-synthesized MoS2catalysts. All the hydrothermally synthesized MoS2catalysts show much higher activity in HDO than the commercial MoS2sample. Among three MoS2catalysts,the one prepared from thiourea,with a high surface area and flower-like morphology, exhibits the highest activity in HDO; over it, a deoxygenation degree of 99. 3% is achieved at 300℃.关键词
