Zirconium metal–organic frameworks (Zr-MOFs) are renowned for their extraordinary stability and versatile chemical tunability. Several Zr-MOFs demonstrate a tolerance for missing linker defects, which create “open sites” that can be used to bind guest molecules on the node cluster.
However, the inevitable shuttle effect of lithium polysulfides and/or dendrite growth of Li metal anodes hinder their commercial viability. Herein, the microporous Zr fumarate metal–organic framework (MOF)-801 (Zr) is considered to produce thin (≈15.6 μm, ≈1 mg cm 2) mixed-matrix membranes (MMM) as a novel interlayer for Li–S batteries.
Here, a more efficient autoxidation self-charging mechanism is realized by introducing hemoglobin (Hb) as a positive electrode additive in the polyaniline (PANI)-zinc battery system. The heme acts as a catalyst that reduces the energy barrier of the autoxidation reaction by regulating the charge and spin state of O 2.
Lithium–sulfur batteries are considered as promising candidates for next-generation energy storage devices for grid applications due to their high theoretical energy density. However, the inevitable shuttle effect of lithium polysulfides and/or dendrite growth of Li metal anodes hinder their commercial viability.
In the Li 2 S 6 -loaded MOF-801 (Zr), a new 13 C site of around 175 ppm emerged and it can be attributed to the thermal decomposition of dioxolane solvent during the preparation of the polysulfides solution since only a correlation between the new 13 C site and the proton from solvent was observed.

Cubic-phase Li 7 La 3 Zr 2 O 12 (LLZO) garnet is a promising solid electrolyte candidate for next-generation Li batteries. As a viable approach, the desired cubic-phase formation of LLZO relies on elemental doping. In this regard, various dopants such as Al and Ga are doped into the LLZO samples, which are synthesized using a solid-state reaction method.

Blumenthal, in contrast, believes that zirconium oxide is almost insoluble in water, acid and alkali solutions, and organic solvents and therefore is not mobile. Indeed, the mobility and/or bioavailability of Zr depend on its chemical form. Certain chemical forms of Zr (e.g., zirconium carbide and zirconium oxychloride) are slightly soluble, whereas others are …
