Summary: Tuning the electronic structure of the active centers in covalent organic frameworks (COFs) is crucial for balancing the adsorption ability and reactivity of oxygen in the 2e(-) oxygen reduction reaction (ORR) for electrocatalytic synthesis of hydrogen peroxide (H2O2). By introducing different by-design building blocks, the adsorption ability of oxygen molecule (O-2) can be finely tuned, and the binding strength of O-2 is positively correlated with the electron-donating ability of the active center. The newly designed TP-TD-COF exhibits higher 2e(-) ORR activity and selectivity due to its stronger electron-donating ability and higher adsorption strength of O-2 on the electron-rich active center. This work reveals the fundamental structure-activity relationship in H2O2 synthesis and provides a strategy for designing metal-free COF catalysts through rational modulation of their electronic properties at the molecular level.

Summary: In this study, core-shelled hybrids of covalent organic frameworks and metal-organic frameworks are constructed to catalyze the oxygen evolution reaction. The high oxygen evolution reaction activity in the core-shelled Co-COF@MOF catalyst is due to the synergetic roles between the Co and Fe sites, which promote the formation of O* from OH*.

Summary: Metal-organic frameworks (MOFs) have potential in electrocatalysis due to their adjustable ligand structures, but their poor stability hinders practical applications. This study introduces an innovative strategy of leveraging metal nodes to enhance both the catalytic activity and stability.

Additionally, the incorporation of Rh into the MOF enabled a robust stability of over 60 hours in seawater electrolyte.

Summary: We have reported a unique vinyl coordination polymer (CP), [Zn(4-Fb)(2)(tkpvb)](n), which can undergo a rare photopolymerization reaction to form a two-dimensional CP integrated with a one-dimensional linear organic polymer. This CP exhibits a phenomenon of photoinduced nonlinear lattice expansion upon light irradiation at different wavelengths. It can be dispersed in polyvinyl alcohol (PVA) to form a composite film, which can undergo various photopolymerization-driven macroscopic mechanical motions when exposed to UV light. These findings provide new insights into the development of CPs-based smart photoactuators, which can be applied in the field of microrobotics.

Summary: This study proposes a systematic approach to screen efficient double-atom catalysts (DACs) for urea production, using nitrogen and carbon dioxide as precursors, with the help of density functional theory (DFT). The results show that co-doped graphdiyne with CrB and MnB double atoms emerge as potential electrocatalysts for urea production, displaying low energy barriers and the capability to suppress the formation of unwanted by-products. The study establishes a theoretical framework for the evaluation of DACs in electrocatalytic urea synthesis.
