A periodic mesoporous organosilica with a basic urea‐derived framework (PMO‐UDF) was prepared and characterized thoroughly. The PMO‐UDF showed an enhanced CO 2 capture capacity at low pressure (≤1 atm) and an exceptional catalytic activity in CO 2 coupling reactions with various epoxides to yield the corresponding cyclic carbonates under mild conditions because of the presence of a high surface area, basic pyridine units, and multiple hydrogen‐bond donors. The highly stable catalyst could be reused at least six successive times without a significant decrease of the catalytic efficiency or structural deterioration, thus the PMO‐UDF composite is considered as a promising material for CO 2 capture and conversion.
