对甲基橙溶液的光催化降解测试结果表明, 600℃为两种方法的最佳热处理温度, 浸渍-水热法制得的催化剂光催化效果明显强于溶胶凝胶法, 且水热法600 ℃热处理的催化剂催化效果强于商品TiO2(P25). 两种负载型催化剂光催化降解甲基橙的反应均符合表观一级动力学方程, 降解率高于自制未负载活性炭TiO2 粉体.

Monolayers of transition metal dichalcogenides (TMDCs) are atomically thin directgap semiconductors with potential applications in nanoelectronics, optoelectronics, and electrochemical sensing. Recent theoretical and experimental efforts suggest that they are ideal systems for exploiting the valley degrees of freedom of Bloch electrons. For example, Dirac valley polarization has been demonstrated in mechanically exfoliated monolayer MoS2 samples by polarization-resolved photoluminescence, although polarization has rarely been seen at room temperature. Here we report a new method for synthesizing high optical quality monolayer MoS2 single crystals up to 25 μm in size on a variety of standard insulating substrates (SiO2, sapphire, and glass) using a catalyst-free vapor
solid growth mechanism. The technique is simple and reliable, and the optical quality of the crystals is extremely high, as demonstrated by the fact that the valley polarization approaches unity at 30 K and persists at 35% even at room temperature, suggesting a virtual absence of defects. This will allow greatly improved optoelectronic TMDC monolayer devices to be fabricated and studied routinely.
