| 1 | Land surface emissivity change in China from 2001 to 2010显示文摘陆地表面放射率是在从热红外线的遥感的温度倒置的重要参数之一。用地的复数 L3 水平产品的 MOD11C3,时间空间的数据在中国陆地表面放射率设定因为从 2001 ~ 2010 的 10 年被获得。结果证明在西北沙漠区域的陆地表面放射率在中国是最低的,与小季节的变化。相反,在陆地表面放射率在有重要季节的变化东北中国和北 Xinjiang, Qinghai 西藏高原,长江山谷和东方、南部的中国。在冬季,在东北中国和北 Xinjiang 的陆地表面放射率相对高。Qinghai 西藏高原区域的陆地表面放射率从 11 月在低价值被维持到三月,当它在另外的月内变得更高时。长江山谷,东方、南部的中国,和四川盆的陆地表面放射率从 7 月变化到 10 月,并且在 8 月达到顶点。陆地表面放射率价值能被划分成五个层次:低放射率(0.61630.9638 ) ,中等低的放射率(0.96390.9709 ) ,中等放射率(0.97100.9724 ) ,中等高度的放射率(0.97250.9738 ) ,和高放射率(0.97390.9999 ) 。分别地,有低放射率,中等低的放射率和中等放射率的区域的百分比是大约 20% , 10% 和 20% 。中等高度的放射率区域完成瓷器陆地表面区域的 40%50% 。中等高度的放射率区域的内部年度的变化也是很清楚的,与二座山峰(在春天和秋天) 并且二马槽(在夏天和冬季) 。高放射率区域的内部年度的变化是很重要的,与在冬季(10%) 的一座山峰,当时仅仅 1% 或 2% 在另外的季节。在瓷器陆地表面放射率和温度的时间空间的分发之间有一个清楚的协会:越高放射率,越多降低温度,并且反过来也如此。放射率是任何对象的一个固有的性质,但是它的放射率的精确的值非常取决于它包围环境因素。 | WANG Xinsheng FAN Jiangwen XU Jing LIU Fei GAO Shoujie WEI Xincai | 2012 | Journal of Geographical Sciences2012，22，3： | 1 |
| 2 | Promoting CO_(2) and H_(2)O activation on O-vacancy regulated In-Ti dual-sites for enhanced CH_(4) photo-production显示文摘Engineering the specific active sites of photocatalysts for simultaneously promoting CO_(2)and H_(2)O activation is important to achieve the efficient conversion of CO_(2)to hydrocarbon with H_(2)O as a proton source under sunlight.Herein,we delicately design the In/TiO_(2)-VOphotocatalyst by engineering In single atoms(SAs)and oxygen vacancies(VOs)on porous TiO_(2).The relation between structure and performance of the photocatalyst is clarified by both experimental and theoretical analyses at the atomic levels.The In/TiO_(2)-VOphotocatalyst furnish a high CH_(4)production rate up to 35.49μmol g^(-1)h^(-1)with a high selectivity of 91.3%under simulated sunlight,while only CO is sluggishly generated on TiO_(2)-VO.The combination of in situ spectroscopic analyses with theoretical calculations reveal that the VOsites accelerate H_(2)O dissociation and increase proton feeding for CO_(2)reduction.Furthermore,the VOregulated In-Ti dual sites enable the formation of a stable adsorption conformation of In-C-O-Ti intermediate,which is responsible for the highly selective reduction of CO_(2)to CH_(4).This work demonstrates a new strategy for the development of effective photocatalysts by coupling metal SA sites with the adjacent metal sites of support to synergistically enhance the activity and selectivity of CO_(2)photoreduction. | Cong Chen Liang Chen Yangguang Hu Ke Yan Ting Wang Youju Huang Chao Gao Junjie Mao Shoujie Liu Benxia Li | 2023 | Journal of Energy Chemistry2023，，11： | 0 |
