近日(ri)，中国科(ke)(ke)学(xue)院(yuan)大(da)连化(hua)学(xue)物理研究(jiu)所(suo)催化(hua)基础国家重点实验室研究(jiu)员(yuan)傅强(qiang)与中科(ke)(ke)院(yuan)院(yuan)士(shi)包信和团(tuan)队，在(zai)金属(shu)(shu)与载(zai)体界面催化(hua)研究(jiu)方面取得(de)新进展。研究(jiu)发(fa)现过渡金属(shu)(shu)催化(hua)剂与惰性(xing)的(de)(de)六方氮化(hua)硼(peng)（h-BN）载(zai)体之(zhi)间存在(zai)经典的(de)(de)金属(shu)(shu)-载(zai)体强(qiang)相互(hu)作用（Strong Metal-Support Interaction, SMSI）。
金属(shu)-载(zai)体(ti)强相(xiang)互(hu)作用是多相(xiang)催(cui)化研(yan)究领域中的(de)(de)(de)重要概念之一。该现象是指当金属(shu)担载(zai)于活性的(de)(de)(de)可还(hai)原氧化物载(zai)体(ti)上时，在一定(ding)的(de)(de)(de)预(yu)处理或催(cui)化反应条件下，金属(shu)纳米粒(li)子被载(zai)体(ti)衍生的(de)(de)(de)材料包裹(guo)和去包裹(guo)的(de)(de)(de)过(guo)程，以及(ji)由此对(dui)催(cui)化反应性能产(chan)生的(de)(de)(de)重要影响(xiang)。
研究发现，惰性的h-BN片层负载金属Ni催化剂在甲烷二氧化碳干重整（DRM）反应中表现出优异的性能，原位表征证明反应气氛中的CO2和H2O组分可以促进Ni/h-BN界面处h-BN片层被氧化刻蚀形成纳米孔洞（nanopits）结构，同时Ni粒子表面被氧化硼（BOx）薄层包裹；包裹和去包裹过程可以通过DRM反应和H2还原进(jin)行可逆控(kong)制，呈现出经典的(de)(de)SMSI现象。这(zhei)(zhei)是首(shou)次在惰性(xing)的(de)(de)非(fei)氧化(hua)物(wu)载体担载金(jin)(jin)属(shu)催(cui)化(hua)剂中(zhong)发现这(zhei)(zhei)一现象，在h-BN担载的(de)(de)其他过(guo)渡金(jin)(jin)属(shu)催(cui)化(hua)剂如Fe、Co和(he)(he)Ru中(zhong)也普遍存(cun)在。此外，金(jin)(jin)属(shu)/h-BN体系中(zhong)发生的(de)(de)DRM反(fan)应诱导SMSI效应会增(zeng)强该催(cui)化(hua)过(guo)程，实(shi)验和(he)(he)理(li)论计算(suan)结果表(biao)(biao)明，界(jie)面处的(de)(de)载体通(tong)过(guo)刻蚀形成的(de)(de)纳米(mi)孔(kong)洞限域金(jin)(jin)属(shu)粒(li)(li)子并阻止(zhi)其团聚，同时金(jin)(jin)属(shu)粒(li)(li)子表(biao)(biao)面形成的(de)(de)无定形BOx包裹层与金(jin)(jin)属(shu)协同作用，使得Ni/h-BN催(cui)化(hua)剂同时具有抗(kang)积碳和(he)(he)抗(kang)烧结的(de)(de)性(xing)能。
