Abstract Graphitic carbon nitride (g‐CN) is a promising heterogeneous metal‐free catalyst for organic photosynthesis, solar energy conversion, and photodegradation of pollutants. Its catalytic performance is easily adjustable by modifying texture, optical, and electronic properties via nanocasting, doping, and copolymerization. However, simultaneous optimization has yet to be achieved. Here, a facile synthesis of mesoporous g‐CN using molecular cooperative assembly between triazine molecules is

A multistep templating procedure is used to prepare graphitic carbon nitride (g-C3N4) and titanium nitride/carbon composites with ordered, 2D hexagonal porosity. First, the carbon nitride is prepared by nanocasting using a silica (SBA-15) template. This carbon nitride is then replicated as a metal nitride carbon composite, using a simultaneous templating/conversion scheme (“reactive templating”). Detailed facts of importance to specialist readers are published as ”Supporting Information”. Such d

Simple organic cooperative assembly of triazine molecules leads to three-dimensional macroscopic assemblies of low-dimensional graphitic carbon nitrides (g-CNs), for example, nanoparticles, nanotubes, and nanosheets. The approach enables the characterization of the cooperative properties and photocatalytic activities of low-dimensional g-CN materials in hydrogen evolution reactions from water under visible light.

I can Cu: Cubic mesoporous graphitic carbon nitride (c-mpg-C3N4) is an all-in-one chemosensor that plays the roles of ligand, fluorophore, and supporting material, enables the simple detection of metal ions, and is highly selective and sensitive to Cu2+.

A turn-on fluorescence sensor, Cu(2+)-c-mpg-C(3)N(4), was developed for detection of CN(-) in aqueous solution by simply mixing cubic mesoporous graphitic carbon nitride (c-mpg-C(3)N(4)) and aqueous solution of Cu(NO(3))(2). The highly sensitive detection of CN(-) with a detection limit of 80 nM is not only possible in aqueous solution but also in human blood serum.

Xanthophylls are oxygenated carotenoids that serve a variety of functions in photosynthetic organisms and are essential for survival of the organism. Within the last decade, major nor advances have been made in the elucidation of the molecular genetics and biochemistry of the xanthophyll biosynthesis pathway. Microalgae, yeast, or other microorganisms produce some of the xanthophylls that are being commercially used due to their own color and antioxidant properties. Currently, only a few microal

Einfache kooperative Zusammenlagerung organischer Triazinmoleküle führt zu dreidimensionalen makroskopischen Aggregaten aus niederdimensionalen graphitischen Kohlenstoffnitriden in Form von Nanopartikeln, -röhren und -blättern. Kooperative Eigenschaften und photokatalytische Aktivitäten dieser Materialien in der Wasserstoffentwicklung aus Wasser unter Bestrahlung mit sichtbarem Licht wurden charakterisiert. As a service to our authors and readers, this journal provides supporting information sup

Titanium oxide (TiO2) is a potential photocatalyst for removing toxic NOx from the atmosphere. Its practical application is, however, significantly limited by its low absorption into visible light and a high degree of charge recombination. The overall photocatalytic activity of TiO2 remains too low since it can utilize only about 4–5% of solar energy. Nitrogen doping into the TiO2 lattice takes advantage of utilizing a wide range of solar radiation by increasing the absorption capability towards

In this study, mesoporous silica SBA-15 was functionalized with primary, secondary, and tertiary amino-functional silanes onto the channel walls using a postsynthesis method as a first attempt to purify succinic acid from a fermentation broth. Ordered mesostructures of pristine and functionalized SBA-15 were evaluated using small-angle X-ray scattering (SAXS), transmission electron microscopy (TEM), and N2 adsorption/desorption isotherms. 13C and 29Si magic-angle spinning (MAS) nuclear magnetic

Unicellular gren algae of the genus Haematococcushave been studied extensively as model organisms for secondarystrong irradiance or nitrogen deficiency, unicellular gren algaeof the genus Haematococcus accumulate secondary carotenoidsin vesicles in the cytosol. Because secondary carotenoidaccumulation occurs only upon specific environmental stimuli,there is speculation about the regulation of the biosyntheticpathway specific for secondary carotenogenesis. Because thecarotenoid biosynthesis pathw

Although sodium hybrid capacitors (NHCs) have emerged as one of the most promising next-generation energy storage systems, further advancement is delayed primarily by the absence of high-performance battery-type anodes. Herein, we report a nature-inspired synthesis route to prepare hard carbon anodes with high capacity, rate capability, and cycle stability for dual-carbon NHCs. Shape- and size-controllable crystal aggregates of inexpensive triazine molecules are utilized as reactive templates th
