Metal-organic frameworks (MOFs), as a very promising category of porous materials, have attracted increasing interest from research communities due to their extremely high surface areas, diverse nanostructures, and unique properties. In recent years, there is a growing body of evidence to indicate that MOFs can function as ideal templates to prepare various nanostructured materials for energy and environmental cleaning applications. Recent progress in the design and synthesis of MOFs and MOF-derived nanomaterials for particular applications in lithium-ion batteries, sodium-ion batteries, supercapacitors, dye-sensitized solar cells, and heavy-metal-ion detection and removal is reviewed herein. In addition, the remaining major challenges in the above fields are discussed and some perspectives for future research efforts in the development of MOFs are also provided.

“…For example, spindle-like porous a-Fe 2 O 3 was prepared from MIL-88-Fe and used for high-rate lithium batteries. 30 In contrast to other precursors, MOFs provide the versatile and abundant choices in designing and constructing the hierarchically structured nanostructures of metal oxides because of their various metal ions, a family of polyfunctional organic compounds and a variety of topological architectures and morphologies. 29 Hierarchical ZnO parallelepipeds were fabricated from Zn-based MOF precursors and used as an efficient scattering layer in dye-sensitized solar cells.…”

Novel hierarchical ZnO hollow cubes are constructed using the interpenetrated 0D nanoparticles through directly decomposing the Zn-based metal-organic frameworks (Zn-MOF, ZIF-8). After decomposition at 450 1C for 1 h, the as-prepared ZnO well maintains the original ZIF-8 shape with relatively high surface area (45 m 2 g À1 ), thereby realizing fast surface reaction kinetics of benzene molecules. In contrast to singular 0D ZnO nanoscale counterparts, the unique ZnO nanostructure assembly renders the well exposed surfaces and defect states, enhancing significantly chemical sensitivity towards gaseous benzene. The present work provides a facile and versatile approach for designing the high-performance chemical sensing materials.

“…This is also proven by the fact that the seminal work of O'Regan and Grätzel is the most cited article in the whole energy field (5) and more than 17,000 papers (SciFinder database) have been written to propose new materials, characterization techniques, and large-scale implementation of DSSCs (7). At present, efficiencies higher than 14% have been obtained (8) and the current research efforts are focused on the improvement of the long-term stability of these devices (9)(10)(11).…”

Glass GlassHowever, despite the record efficiency of 14.3% and the recent large-scale industrial production, DSSCs still depend on oil-derived electrolytes and nanostructured electrodes designed by expensive templating agents.This trend is changing, and in recent years the scientific community has started to propose natural polymers as substitutes for the more expensive and oil-derived materials. In this article, we present some electrolytes and electrodes developed with these new materials and demonstrate how the DSSC device is gradually approaching the highly cited and mentioned artificial leaf.
