The invention provides a supported catalyst, which comprises a carrier and an active metal component and an auxiliary agent which are loaded on the carrier. The active metal component is a Ni component and/or a Co component and has the dispersion degree being 6-15%. The invention further provides a preparation method and application of the supported catalyst and a method for preparing synthetic gas through methane dry reforming. The supported catalyst can obviously improve the dispersity of the active metal component, is small in size of active metal particles, and is excellent in catalytic activity, stability and carbon deposition resistance. 本发明提供了种负载型催化剂，其中，所述催化剂含有载体以及负载在载体上的活性金属组分和助剂，其中，所述活性金属组分为Ni组分和/或Co组分，所述活性金属组分的分散度为6-15％。本发明还提供了种负载型催化剂的制备方法和应用以及甲烷干重整制合成气的方法。本发明提供的负载型催化剂能够得到显著提高的活性金属组分的分散度和较小的活性金属晶粒尺寸，具有较高的催化活性和稳定性以及抗积炭性能。
