ABSTRACT = {Under the driving goal of carbon neutrality, biogas reforming technology has garnered significant attention due to its ability to convert greenhouse gases (CH<sub>4</sub>/CO<sub>2</sub>) into syngas (H<sub>2</sub>/CO). Conventional nickel-based catalysts suffer from issues such as carbon deposition, sintering and sulfur poisoning. Non-nickel-based perovskite materials, with their tunable crystal structure, dynamic oxygen vacancy characteristics, and excellent anti-coking/anti-sulfur performance, have emerged as a promising alternative. This review systematically summarizes the design for non-nickel-based perovskite materials, including optimizing lattice oxygen migration ability and active site stability by A/B site doping, defect engineering and heterojunction construction. The enhancing the conversion rate of CH<sub>4</sub>/CO<sub>2</sub> by using the carbon oxidation mechanism mediated by oxygen vacancies, and maintaining good durability in complex biogas environments containing H<sub>2</sub>S, NH<sub>3</sub>, etc. The photo-thermal synergistic catalysis further improves the reaction efficiency through energy coupling. However, challenges such as long-term operational stability (high-temperature lattice reconstruction), the cost of large-scale preparation and the synergistic poisoning effect of sulfur and water are still challenges for practical application. In the future, it is necessary to combine high-throughput computation, <i>in situ</i> characterization and multi-technology coupling to promote the leap of non-nickel-based perovskites materials from laboratory to industrial biogas reforming units.},
