“…At the same time, the CNTs, as high‐speed channel of electron transfer, reduce recombination rate of electrons and holes, resulting in most of the electrons participating in photocatalytic process. The electrons of the CB or CNTs can react with the O 2 dissolved in water to generate ⋅O 2− radicals or other radicals . Besides, outstanding absorb ability of the CNTs can absorb organic pollutant molecules.…”

Recently, visible‐light response and high–efficient photocatalysis for polycyclic organic pollutants of cancer risk has attracted great attention. However, the efficient control and heterojunction fabrication of nanocomposite catalysts for enhanced separation and transfer of interfacial charges remains challenging. Herein, a ternary heterojunction composite photocatalyst (HTTC) was fabricated by utilizing the ultrathin layered titanium dioxide (TiO2) nanostructures, with photocatalytic reactive facets (A101 and R101) prepared from the commercially available TiO2, coating onto outside surface of multi‐walled carbon nanotubes (CNTs) with chemical connection of Ti‐O=C and Ti‐O−C bond, and then the single layer H2TCPP molecules chemically coated onto outside surface of ultrathin layered TiO2 nanostructures with formation of Ti−O‐C=O chemical bond by layer‐by‐layer (LbL) assembly. The interface layer synergistic effects greatly enhance photocatalytic efficiency for high concentrations solution of polycyclic organic pollutants (methylene blue (MB), Rhodamine B (RhB) and oxytetracycline (OTC) under visible light irradiation, and the photodegradation rates of the photocatalysts for MB (and RhB) were 61 times (and 8 times) higher than that of pure P25. The joint interfacial fabrication strategy and composite engineering affords us a facile guideline for the nanocomposite photocatalysts for environmental protection and ecological conservation.

“…Although the nature of this emission is not completely assessed, it is commonly accepted that it is due to surface defects, including OH‐ groups and oxygen vacancies. It is also known that the PL signal emitted from diatom skeletons can depend on the metal‐oxygen complexes caused by metal traces that can be found in silica frustules . Ref.…”

Nanostructured porous materials promise a next generation of innovative devices for healthcare and biomedical applications. The fabrication of such materials generally requires complex synthesis procedures, not always available in laboratories or sustainable in industries, and has adverse environmental impact. Nanosized porous materials can also be obtained from natural resources, which are an attractive alternative approach to man-made fabrication. Biogenic nanoporous silica from diatoms, and diatomaceous earths, constitutes largely available, low-cost reservoir of mesoporous nanodevices that can be engineered for theranostic applications, ranging from subcellular imaging to drug delivery. In this progress report, main experiences on nature-derived nanoparticles with healthcare and biomedical functionalities are reviewed and critically analyzed in search of a new collection of biocompatible porous nanomaterials.
