Abstract
This work is aimed at the development of bimetallic (Ni0.2Cu0.8) catalysts with hexagonal boron nitride (h-BN) nanosheet (BNNS) supports and elucidating their catalytic activity in the methanol steam reforming and CO oxidation reactions. The hybrid Ni0.2Cu0.8/BN catalysts consist of curved h-BN nanosheets, up to 10–20 nm in lateral size, decorated with metallic nanoparticles, 3.0–8.2 nm in dimensions. The methanol conversion starts at ~20 °C and is nearly completed at 320 °C. The (Ni0.2Cu0.8)/BN nanohybrids exhibit high catalytic stability and high selectivity for CO2 over the whole temperature range. No carbon monoxide is detected during full methanol conversion. The possible mechanism of CO utilization during methanol reforming is proposed using ab initio calculations. The onset temperature of catalytic CO oxidation is 100 °C and full conversion is completed at 200 °C. These results indicate high catalytic efficiency of (Ni0.2Cu0.8)/BN nanohybrids in methanol steam reforming and CO oxidation reactions.
