Owing to the depletion of fossil reserves and the global warming by released greenhouse gas from the consumption of fossil resources, the catalytic conversion of carbon oxide (CO x , including CO 2 and CO) into fuels and high‐value chemicals has attracted tremendous interest in the field of catalysis. Developing high‐performance and practical catalysts with high activity, selectivity, and stability is of great importance but remains a huge challenge. A variety of new strategies were developed to take advantage of confinement effect to address the challenges that are relevant to the highly‐efficient transformation and utilization of CO x by performing catalytic reactions in a confined space. The status on this issue can be divided into three aspects: improvement in catalytic activity, increase in catalytic selectivity and enhancement in catalytic stability. In this review, the progress in the field of promoted catalytic conversion of CO x in confined spaces will be presented and discussed. Especially, the specific promoting mechanism in terms of the confinement effect for CO x ‐related transformations in confined spaces and the relationship between the impact of the confined space on the catalytic activity, selectivity, and stability regarding of CO x conversions are highlighted. Finally, the future prospects on the opportunities and challenges of catalytic conversion of CO x in confined spaces are outlined.
