Cover Story: CO2 is not only the greenhouse gas mainly responsible for human-induced climate change, but also a raw material that should be utilized. By using solid catalysts, CO2 can be converted into high value products with the help of green hydrogen. This review compares recent studies on catalysts for the methanation of CO2 in biogas. Methanation of biogas leads to new challenges for catalysts due to the presence of CH4 and catalyst-poisoning trace compounds such as H2S. Both CH4 and H2S have been shown to affect catalyst activity. Increased sulfur resistance of Ni and noble metal catalysts could be attributed to certain promoters and reducible support materials. This review highlights open questions and innovative research approaches. View this paper.
