Decomposition of Methanol Catalyzed by Cu-ZnO@C

Hong C.-I., Kang H.Y., Chang F-C, Paul Wang H., National Cheng Kung University, TW

Decomposition of methanol (DM) to CO and H2 can be catalyzed by Cu-ZnO@C core-shell nanoreactors. It is found that reactivity of DM catalyzed by the nanoreactors increase with an increase in the fractions of ZnO [...]

Photocatalytic Performance of Ag modified and doped TiO2 nanoparticles

Cho C-P, Chang L.-H., National Chi-Nan University, TW

In this work, TBOT was used as the titanium source for preparation of TiO2 nanoparticles, followed by calcination at 500°C for 2 hours to achieve fine TiO2 nanoparticles powder (S1). The obtained S1 powder was [...]

Life Cycle Assessment for Assessing Carbon Footprints of Water Supply System in Taiwan

Hu A.H., Huang C-Y, Huang C-Y, Fan C-W., National Taipei University of Technology, TW

This study aims to calculate the carbon footprints of two water supply systems in Taiwan, one is a traditional water treatment plant (FYWTP) and another is a seawater desalination plant (KSDP) and each with different [...]

Adsorption of Tetramethylammonium Hydroxide (TMAH) on Y-type Zeolite

Chang S., Lu C., National Chung Hsing University, TW

Y-type zeolite have high TMAH removal efficiency when pH>4 with solid-liquid ratio (S/L) of 2 g/L in 20 minutes. The correlation coefficients of Langmuir and Freundlich isotherm models are 0.973 and 0.997, respectively. The exponential [...]

Deposition of TiO2/Ni/CuO/ITO multi-layered cell for solar-driven water splitting

Wu K.R., National Kaohsiung Marine University, TW

In this study, a photoelectrolysis cell based on multilayered TiO2/Ni/CuO (M-cell) photoelectrode is prepared on ITO substrate (110 nm thick) using a multi-target direct current and radio-frequency magnetron sputtering technique in which Ni acts as [...]
