Disclosed is a supported nanoparticle catalyst, methods of making the supported nanoparticle 5 catalysts and uses thereof. The supported nanoparticle catalyst includes catalytic metals M1, M2, M3, and a support material. M1 and M2 are different and are each selected from nickel (Ni), cobalt (Co), manganese (Mn), iron (Fe), copper (Cu) or zinc (Zn), wherein M1 and M2 are dispersed in the support material. M3 is a noble metal deposited on the surface of the nanoparticle catalyst and/or dispersed in the support material. The nanoparticle catalyst is 10 capable of producing hydrogen (H2) and carbon monoxide (CO) from methane (CH4) and carbon dioxide (CO2). 公开了负载型纳米颗粒催化剂，制备负载型纳米颗粒催化剂的方法及其应用。所述负载型纳米颗粒催化剂包含催化金属M、M、M和载体材料。M和M不同并各自选自镍(Ni)、钴(Co)、锰(Mn)、铁(Fe)、铜(Cu)或锌(Zn)，其中M和M分散在载体材料中。M是沉积在纳米颗粒催化剂表面上和/或分散在载体材料中的贵金属。所述纳米颗粒催化剂能够从甲烷(CH)和二氧化碳(CO)产生氢气(H)和氧化碳(CO)。
