3D Ordered Macroporous Mn, Zr-Doped CaCO Nanomaterials for Stable Thermochemical Energy Storage.

Developing high-performance Ca-based materials that can work for long-term heat transfer and storage in concentrated solar power plants is crucial to achieve the large-scale conversion of solar photon fluxes to dispatchable electricity. This work demonstrates that a series of Mn, Zr co-doped CaCO nanomaterials with the 3D ordered macroporous (3DOM) skeletons are successfully prepared by a novel strategy of templated metal salt co-precipitation. The characterization results indicate that a majority of Zr and Mn are atomically dispersed into the highly-crystallized CaCO framework, whereas a minor amount of Mn is present in the form of CaMnO nanoparticles (NPs).

Magnetic Chitosan/ZrO Composites for Vanadium(V) Adsorption while Concurrently being Transformed to a Dual Functional Catalyst.

Spent adsorbents for recycling as catalysts have drawn considerable attention due to their environmentally benign chemistry properties. However, traditional thermocatalytic strategies limit their applications. Here, we developed an enhanced photocatalytic strategy to expand the range of their applications.
