N-doped NaTaO3 synthesized from a hydrothermal method for photocatalytic water splitting under visible light irradiation

Journal of Energy Chemistry 2017年第3期26卷 515-521页

作者： Che-Chia Hu hui-hsin Huang Yu-Chi Huang Department of Chemical Engineering and R&D Center for Membrane Technology Chung Yuan Christian UniversityTaoyuan City 32023TaiwanChina

NaTaONcatalysts were synthesized by a hydrothermal（H） and a solid-state（S） methods in this *** H-and S-NaTaONsamples were characterized by X-ray diffraction（XRD）, scanning electron microscopy（SEM）, transmission electron microscopy（TEM）, UV–visible（UV–vis） diffuse reflectance spectroscopy, and photoluminescence（PL） spectroscopy. The XRD patterns of the H-and S-samples showed peaks indexed to the pure phase of perovskite NaTaOand minor peaks assignable to TaNat various synthesis temperatures. Substitution of oxygen by nitrogen ions causes the light absorption of the H-and S-NaTaONsamples to be extended to the 600–650 nm region, thus making the samples visible-light active. The NaTaONsamples exhibited photocatalytic activity for Hand Oevolution from aqueous methanol and silver nitrate solutions under visible-light irradiation. The UV–vis and PL spectra of the Hand S-catalysts revealed the presence of cationic vacancies and reduced metallic species, which acted as recombination centers. These results demonstrated that the preparation method plays a critical role in the formation of defect states, thereby governing the photocatalytic activity of the NaTaONcatalysts.

Interpurchase Time of Customer Behavior in Cloud Computing

引用

Journal of Electronic Science and Technology 2013年第2期11卷 197-200页

作者： hui-hsin Huang Department of Business Administration Aletheia University

Cloud computing is an increasingly popular paradigm for accessing computing resources. For marketing application, this paper proposes a dynamic model of customer interpurchase time with geometric distribution. This model considers that there is a change point in interpurchase time and two types of probability density functions are demonstrated （time decreasing before changing; time increasing after changing）. With the description of change point, Bernoulli and Poisson distributions also are discussed in the model construction.

Aldosteronoma causing Conn’s syndrome: a case report and literature review

引用

Health 2009年第4期1卷 269-273页

作者： hsin-hui Shao Hock-Liew Eng Wen-Sheng Huang Joseph Nybo Lin 不详

We report a case of primary aldosteronism caused by bilateral solitary aldosteronomas occurring 6 months apart, the diagnosis being confirmed by clinical features. Multiple aldos-terone-producing adenomas can be unilateral or bilateral. If bilateral, most of them are found simultaneously. Bilateral solitary aldosterono-mas occurring at separate times are rarely re-ported and the pathogenesis is still elusive. We believe, from this case, the postoperative fol-low-up in patients with primary aldosteronism is mandatory.
