Based on the superior chemical and thermal stability of hexagonal boron nitride (h-BN), we design and synthesize h-BN supported mesoSiO-confined Ni catalysts with a stable architecture. The as-prepared catalyst exhibits excellent coke- and sintering-resistance performance in the dry reforming of methane, and especially, there is almost no loss of activity even after a 100 h stability test due to the synergistic effects of the h-BN interface and Ni nanoparticles.
基于六方氮化硼(h-BN)优异的化学和热稳定性,我们设计并合成了具有稳定结构的h-BN负载的介孔SiO限制的Ni催化剂。所制备的催化剂在甲烷干重整中表现出优异的抗积炭和抗烧结性能,特别是由于h-BN界面和Ni纳米颗粒的协同作用,即使经过100小时的稳定性测试后活性几乎没有损失。
