Adsorption and photoconversion of CO2 are alternative methods to reduce global gas emissions. However, to get optimal results, a material with specific properties is needed to increase the efficiency of removal and conversion of CO2. Currently, mesoporous-based materials are getting much attention to be developed for adsorption and photocatalyst CO2 because they have a large specific surface area. However, these characteristics are still likely to continue to be improved in various ways. This review summarized some potential ways to increase adsorption capacity and photoconversion of CO2 compounds through the synthesis of routes, modifications, and composite systems. In addition, this review has also discussed the application of mesoporous materials for smart surfaces by paying attention to the toxicity and stability value of the material. Expectantly, this review can be used for references to develop mesoporous materials that focus on CO2 adsorption and conversion in the future.
