摘要
丙烷是一种非常重要的化工原料,广泛地应用于大量化工产品的工业生之中丙烷一般被称为液化石油气,是石油裂解生产汽油和燃料油过程中的副产物。有限的石油储备和低产率导致丙烷的生产难以满足日益增长的生产生活的需求。丙烷脱氢反应(PDH)以及页岩气的发现为丙烯的工业生产提供了另一条路径。相较于储备量小、价格较贵的石油,页岩气储备量大、价格低廉,为丙烷脱氢制丙烯的工业化成产奠定了坚实的基础。在丙烷脱氢反应中,催化剂起着至关重要的作用。尽管丙烷脱氢反应已经工业化,但目前丙烷脱氢催化剂依然存在许多挑战。例如活催化性差,目标产物选择性低,热稳定性差。在此报告中,我们制备了一种铂铟双金属催化剂。通过胶体合成技术,在水相中通过改变前躯体的量调控铂铟纳米颗粒的尺寸和组分。铂铟之间的协同作用,可以有效的提高催化剂的活性、选择性和稳定性。这种双金属催化剂的设计理念为催化剂合成有重要的指导意义。
As extensively used chemical building blocks, propane is one of the most important compounds in the chemical industry. Propane is obtained as the by-product during petroleum cracking to produce gasoline and fuel oil. However, the increasing demand for propane can't be satisfied due to the limited crude oil and relatively low selectivity to the desire product. Recently, increasing attention has been paid on the propane dehydrogenation with the founding of shale gas. Production of propane based on PDH reaction has great advantage over through oil cracking because of huge amount of shale gas reserve and low cost. Catalyst is the key in the dehydrogenation process and nowadays, Pt-based and Cr Ox-based catalysts already have a good application in the propane dehydrogenation industry. However, low catalytic activity and selectivity, poor stability as well as high cost are still in front of these catalysts, which promotes the modification of these catalysts and exploration of new catalysts. In here, we report one controllable synthesis method of Pt-In binary metal catalyst. The particle size and composition can be adjusted through changing the amount of precursor. The synergistic effect between Pt and In atom do help to promote the catalytic performance. This colloidal synthesis method provide a good way to synthesis other new materials.
