“…Calculating the surface area of native Sorites (after removing the top layer) using the Brunauer–Emmett–Teller theory yields a value of ≈5 m² g −1 . This value is comparable to the surface area reported for other biological scaffolds in use (1.4–51 m² g −1 ) . Coating Sorites with Co followed by etching of the template doubled the surface area of the structures (≈8 m² g −1 ).…”

Given their unique properties, tremendous progress is realized in the use of nanostructured materials for various applications. However, their incorporation and fabrication into prototypic devices remain challenging due to their limited ability to form hierarchical 3D structures through the use of large scale, low cost, and facile processes. Herein, this challenge is addressed and the growth of unique hierarchical structures is demonstrated by coating calcareous foraminiferal shells with metal oxide materials via simple and inexpensive processes conducted on a large scale. Foraminifera are highly diverse and abundant marine unicellular protists surrounded by large, ranging from 0.1 mm to more than 200 mm in size, identical porous, and complex hierarchical shells. In the present study, these hierarchal structures are investigated in electrochemical water oxidation reactions and tested in terms of their ability to purify water from inorganic (metal ions) contaminates. The remarkable performances of the prototype filters and catalysts developed here, among the best recorded values in both fields, are reported. These findings thus open new perspectives for catalytic and water purification applications.

In the present study, the authors have synthesized biosilica from marine diatoms (Amphora sp.) by using an optimized procedure with a combination of acid and salt washing treatments. The purification of frustules employed a simple methodology that combines acid digestion and rinsing with hydrogen peroxide. The content of Amphora sp. biosilica has been analyzed through energy-dispersive spectroscopy. The result declares the purity of biosilica, which is highly pristine in comparison to diatomaceous earth. The structural architecture of Amphora sp. is typically amorphous in nature. Moreover, Amphora sp. biosilica has a mesopore diameter and a surface area of 4·838 nm and 332 m2/g, respectively, which are relatively higher than those from previous reports. The adsorption/desorption isotherm results suggest that the derived frustules have a highly porous architecture, which shows their great potential to be used as drug delivery carriers, biosensors, biocatalysts and adsorbents in the future.
