Copolymerization with 2,4,6-triaminopyrimidine (TAP) is developed for precise substitution of one nitrogen carbon atom in the triazine ring polymeric g-C3N4. Direct incorporation C4N2 from TAP into network retains structural features g-C3N4, but induces rolling-up g-C3N4 sheets tubular configuration. The band gap energy narrowed 2.7 to 2.4 eV by a negative shift valence photocatalyst, which enhances charge-carrier migration and separation, leading higher photocatalytic activity NO gas...
In the semiconductor photocatalyst system for overall water splitting, cocatalysts play crucial roles because they provide not only redox active sites but also charge separation function photogenerated electrons and holes. this work, we have investigated cubic structured NaTaO3 with six equivalent {001} facets to address following two important questions: Can occur among facets? How can charges be separated on surface photocatalytic reactions? Charge location probe experiments by...
Development of a simple and efficient strategy for improving the catalytic activity cobalt-based catalysts toward hydrogen evolution from sodium borohydride (NaBH4) is paramount but remains challenging. Here, we reported facile approach to tune performance NaBH4 hydrolysis with Co-based prepared by using cobalt sulfate as precursor or mixture sulfur-containing salts/cobalt salts raw material. With use precursor, CoSO4-doped Co3O4 sample was formed it exhibited excellent generation ∼500 mL...
NAD(P)H cofactor is a critical energy and electron carrier in biocatalysis photosynthesis, but the artificial reduction of NAD(P)+ to regenerate bioactive 1,4-NAD(P)H with both high activity selectivity challenging. Herein, we found that coupled system Ni3S2 electrode Rh complex an electrolyte (denoted as Ni3S2-Rh) can catalyze superior selectivity. The optimized 1,4-NADH be up 99.1%, much higher than for (80%); normalized Ni3S2-Rh about 5.8 times 13.2 complex. performance attributed...
Rare-earth (Eu 3+, Tb 3+) ion co-doped YBO 3 phosphors with a morphology of uniform flower-like assembly are fabricated by facile hydrothermal method without the use surfactant, organic ligands, or further sintering treatment. Photoluminescence (PL) studies have demonstrated that under excitation 365 nm ultraviolet (UV) light, 3:Tb Eu 3+ emits white including three emissions: blue band attributed to self-trapped excitons (STEs), green due transition 5D 4– 7F j ( = 6, 5, 4, and 3), red 0– 0,...
In this paper, a 'green' and safe hydrothermal method has been used to reduce graphene oxide produce hemin modified nanosheet (HGN) based electrochemical biosensors for the determination of l-tyrosine levels. The as-fabricated HGN were characterized by UV–visible absorption spectra, fluorescence Fourier transform infrared spectroscopy (FTIR) spectra thermogravimetric analysis (TGA). experimental results indicated that was successfully immobilized on reduced (rGO) through π–π interaction. TEM...
Ultrasmall CoO<sub>x</sub> nanoparticles on sulfonated graphite exhibit highly efficient water oxidation activity and can be used for electrochemical solar oxidation.
Developing the ability to synthesize compositionally and morphologically well-defined gibbsite particles with high yield is an ongoing need that has not yet achieved required level of rational design. Here we report optimization a clean inorganic synthesis route based on statistical experimental design examining influence Al(OH)3 gel precursor concentration, pH, aging time at temperature. At 80 °C, optimum conditions concentration 0.5 M, pH 9.2, 72 h maximized reaction up ∼88%. The resulting...
We present a general hydrothermal method without any organic solvent or surfactant for the synthesis of YBO3:Eu3+ nano- and micro-structures. The samples were excellent quality with uniform, well dispersed, self-assembled self-purified YBO3:Eu3+. Single crystal nanoflakes gathered together to evolve into hierarchical architecture eight different types three dimensional morphologies. Strong photoluminescence spectra obtained at 592, 611 627 nm excitations wavelengths 254 363 nm. emission are...
Development of photocatalytic oxygen evolution reaction (OER) and hydrogen (HER) photocatalysts with a narrow bandgap is important for solar water splitting. Herein, Sr 2 CoWO 6 double perovskites light absorption edge ≥700 nm are synthesized by solid‐state method varying the precursor ratios. The sample Co/W ratio 1:4 has conduction band (CB) valence (VB) located at −0.82 0.95 V versus normal electrode (NHE) pH = 7, respectively. As result, both OER HER observed even without loading any...
