Investigation on the Active Sites for NO Oxidation Reaction over MnOx-CeO2 catalysts

24-Mar-2017 | Zhihui Sun; Jun Wang; Jinxin Zhu; Chen Wang; jianqiang wang; Meiqing Shen, New Journal of Chemistry, 2017

MnOx-CeO2 is a potential substitute for commercial Pt-based diesel oxidation catalyst. To better investigate its active sites for NO oxidation reaction, a series of MnOx-CeO2 samples with low Mn doping amounts (≤ 5%) were synthesized by the incipient-wetness impregnation method. The catalysts ...

Correlating Carrier Density and Emergent Plasmonic Features in Cu2–xSe Nanoparticles

17-Mar-2017 | Lauren E. Marbella; Xing Yee Gan; Derrick C. Kaseman; Jill E. Millstone, Nano Letters, 2017

Recently, a wide variety of new nanoparticle compositions have been identified as potential plasmonic materials including earth-abundant metals such as aluminum, highly doped semiconductors, as well as metal pnictides. For semiconductor compositions, plasmonic properties may be tuned not only by ...

Materials, Vol. 10, Pages 309: ZT Optimization: An Application Focus

17-Mar-2017 | Tuley, Richard ; Simpson, Kevin, Materials, 2017

Significant research has been performed on the challenge of improving thermoelectric materials, with maximum peak figure of merit, ZT, the most common target. We use an approximate thermoelectric material model, matched to real materials, to demonstrate that when an application is known, average ...

Modulation‐Doped In2O3/ZnO Heterojunction Transistors Processed from Solution

15-Mar-2017 | Dongyoon Khim, Yen‐Hung Lin, Sungho Nam, Hendrik Faber, Kornelius Tetzner, Ruipeng Li, Qiang Zhang, Jun Li, Xixiang ..., Advanced Materials, 2017

This paper reports the controlled growth of atomically sharp In2O3/ZnO and In2O3/Li‐doped ZnO (In2O3/Li‐ZnO) heterojunctions via spin‐coating at 200 °C and assesses their application in n‐channel thin‐film transistors (TFTs). It is shown that addition of Li in ZnO leads to n‐type doping and ...
