Abstract In response to the global climate change and energy crisis, electrocatalytic CO 2 reduction reaction (ECR) is regarded as one of potential ways simultaneously reach conversion obtain various value‐added products. Currently, several challenges remain for in‐depth understanding ECR from fundamentals, including ambiguous structure‐activity relationships, uncontrollable catalytic selectivity, complex mechanisms. Compared traditional metal nanoparticle‐based materials, atomically dispersed catalysts (ADCs) have aroused significant interest owing their maximal atomic utilization simplified site configuration, offering a superior platform discussing relationships during ECR. Especially, adjacent pairs (AAPs) within ADCs are gradually emphasized novel concept follow synergistic mechanisms Herein, first time broad AAPs analyzed how reached effect summarized. view varying on different supports, three types supports illustrated (containing graphene model, functional porous frameworks, metals oxides), aiming help scholars with more insights in broadening feasible ADCs.

Abstract Exploiting advanced amphiphilic solid catalysts is crucial to the development of Pickering emulsion catalysis. Herein, covalent organic framework (COF) nanoparticles constructed with highly hydrophobic monomers as linkers were found show superior amphiphilicity and they then developed a new class emulsifiers for Employing COFs emulsifiers, emulsions controllable type droplet sizes obtained. COF materials have also been demonstrated serve porous surface coatings replace traditional modifications stabilizing emulsions. After implanting Pd into COFs, obtained catalyst displayed 3.9 times higher catalytic efficiency than in biphasic oxidation reaction alcohols. Such an enhanced activity was resulted from high area regular structure COFs. More importantly, because their tunable pore diameters, catalysis remarkable size selectivity achieved. This work first example that applied catalysis, providing platform exploring frontiers
