Size-dependent capacitance of NiO nanoparticles synthesized from Ni-based coordination polymer precursors with different crystallinity

Battery-like behavior of Ni-ceria based systems: Synthesis, surface defects and electrochemical assessment

“…suggests a size-dependent electrochemical performance enhanced with decreasing particles size, as reported in previous works [64,65]. Indeed, peak currents recorded in cyclic voltammetry of the NiO-CeO 2 electrode are higher than those of NiO-CGO (Fig.…”

Porous Cobalt Metal–Organic Frameworks as Active Elements in Battery–Supercapacitor Hybrid Devices

“…On the basis of the overall results, the PCN electrode showed excellent performances without the aid of the conductive matrix, illustrating that large porous MOFs could be good candidates for a further study in the BSH device. In comparison with other alkaline BSH or energy-storage devices with superlong cycling lives, , the cycling endurance for pristine MOFs is still a choke point to be addressed. − Therefore, how to prepare stable and conductive large porous MOFs would be a focal point rather than just physically compositing with conductive materials in the future.…”

Recent Progress in Stimulus-Responsive Two-Dimensional Metal–Organic Frameworks

“…Metal–organic frameworks (MOFs) − have already displayed many natural features, for example, structural diversity and flexibility, tunable sizes and shapes, high porosity, remarkable open activity sites, and large surface area. − Within the frameworks, various swelling modes and adjustable secondary building blocks (SBBs) endow the MOFs to perfectly meet the requirements of the stimuli-responsive materials. More importantly, the elaborate selection of metal nodes comprising sole metal centers, multiple metal sites or metal clusters and the versatile SBBs could be arbitrarily chosen from the molecular level, which makes them much “smarter” in comparison to peer competitors …”
