What is Bimetallic Rh–Ni/BN catalyst for methane reforming with CO2 about?
The dry reforming of methane (CH 4 ) with carbon dioxide (CO 2 ) was carried out using bimetal (Rh-Ni)loaded boron nitride (BN) and ␥-Al 2 O 3 catalysts. The incipient wetness method was used to load different ratios of Rh/Ni on BN and ␥-Al 2 O 3 supports. The metal particles were too small to be observed in the XRD indicating highly dispersed Rh-Ni particles on the supports. XPS results showed that, after H 2 reduction at 500 • C, Rh became metallic element while most Ni remained in its oxidized state. The addition of Rh increased the activity of dry reforming as well as the stability of the catalysts. In general, the conversions of CH 4 with CO 2 on Rh-Ni/BN catalysts were higher than those on Rh-Ni/␥-Al 2 O 3 catalysts. The optimum ratio of Rh/Ni loading on BN was 0.01. The ratio of H 2 and CO as the products was near 0.7. The maximum conversions of CH 4 and CO 2 reached 72% and 81%, respectively, at 700 • C, while only slight deactivation was observed after 6 h of reaction time. Boron nitride has many unique properties, such as inertness and negligible metal-support interference, as compared with traditional oxide supports. Metal particles can migrate freely and easily to form
