The fundamentals and challenges of CO<sub>2</sub>-to-C<sub>2+</sub> reduction are first introduced. Then, we summarized design conceptions of MOF-based Cu catalysts from three aspects: engineering the electronic properties of Cu, regulating the local reaction environment, and managing site exposure and mass transport. Further, the latest progress of CO<sub>2</sub> reduction to C<sub>2+</sub> products over MOF-based Cu catalysts, namely Cu-based MOF, MOF-derived Cu, and Cu@MOF hybrid catalysts, are discussed.

In our stent coating, the incorporated Cu acts as a sustainable catalyst for converting endogenous NO donors into NO, and the immobilized arginine serves as a precursor for NO generation under the effect of endothelial nitric oxide synthase (eNOS). The presence of heparin endows the stent coating with anticoagulant ability and enhances eNOS activity, whilst rapid capture of EC by VEGF accelerates re-endothelialization.

The conjugated VEGF contributes to the formation of a new and intact endothelium on the stent surface to counteract inappropriate vascular cell behaviors. The long-lasting NO flux inhibits smooth muscle cell (SMC) migration and prevents its excessive proliferation, reducing the risk of endothelial hyperplasia.
