Chem. Mater.最新综述: 基于仿光合作用的半导体纳米线——杨培东出品
|
|||||||||
|
纳米线可以被定义为一种具有在横向上被限制在100纳米以下（纵向没有限制）的一维结构。悬置纳米线指纳米线在真空条件下末端被固定。典型的纳米线的纵横比在1000以上，因此它们通常被称为一维材料。根据组成材料的不同，纳米线可分为不同的类型，包括金属纳米线，半导体纳米线和绝缘体纳米线。纳米线均在实验室中生产，截至2014年尚未在自然界中发现。纳米线可以由悬置法、沉积法或者元素合成法制得。悬置纳米线可以通过对粗线的化学刻蚀得来，也可以用高能粒子（原子或分子）轰击粗线产生。 Semiconductor Nanowires for Artificial Photosynthesis 共8页 引文82篇 Chong Liu,†,§ Neil P. Dasgupta,† and Peidong Yang* ,†,‡,§ †Department of Chemistry and ‡Department of Materials Science and Engineering, University of California, Berkeley, California 94720, United States §Materials Science Division, Lawrence Berkeley National Laboratory, Berkeley, California 94720, United States * E-mail: p_yang@berkeley.edu. Biographies Peidong Yang received a B.S. in chemistry from University of Science and Technology of China in 1993 and a Ph.D. in chemistry from Harvard University in 1997. He did postdoctoral research at University of California, Santa Barbara before joining the faculty in the Department of Chemistry at the University of California, Berkeley in 1999. He is currently professor in the Department of Chemistry, Materials Science and Engineering and a senior faculty scientist at the Lawrence Berkeley National Laboratory. He is S. K. and Angela Chan Distinguished Chair Professor in Energy. He was recently elected as MRS Fellow and is a member of American Academy of Arts and Sciences. He is the deputy director for the Center of Integrated Nanomechanical Systems. He is one of the founding members for DOE Energy Innovation Hub: Joint Center for Arti fi cial Photosysn- thesis (JCAP) and served as its north director for the fi rst two years. Yang is an associate editor for Journal of the American Chemical Society and also serves on editorial advisory board for number of journals including Accounts of Chemical Research and Nano Letters. He was the founder of the Nanoscience subdivision within American Chemical Society. He has co-founded two startups Nanosys Inc. and Alphabet Energy Inc. He is the recipient of MRS Medal, Baekeland Medal, Alfred P. Sloan research fellowship, the Arnold and Mabel Beckman Young Investigator Award, National Science Foundation Young Investigator Award, MRS Young Investigator Award, Julius Springer Prize for Applied Physics, ACS Pure Chemistry Award, and Alan T. Waterman Award. According to ISI (Thomas Reuters), Yang is ranked as No. 1 in materials science and No. 10 in chemistry for the past 10 years based on average citation per paper, and he has an h-index of 105. His main research interest is in the area of one dimensional semiconductor nanostructures and their applications in nanophotonics and energy conversion. ABSTRACT: In this Perspective, we discuss current challenges in artificial photosynthesis research, with a focus on the bene fi ts of a nanowire morphology. Matching the fl ux between electrocatalysts and light-absorbers, and between individual semiconducting light-absorbers, are two major issues to design economically viable devices for arti fi cial photosynthesis. With the knowledge that natural photosynthesis is an integrated nanosystem, individual building blocks of biomimetic arti fi cial photosynthesis are discussed. Possible research directions are presented under an integrated device design scheme, with examples of our current progress in these areas. Coupling all of the components together, including electrocatalysts, light-absorbers, and charge transport units, is crucial due to both fundamental and practical considerations. Given the advantages of one-dimensional nanostructures, it is evident that semiconductor nanowires can function as essential building blocks and help to solve many of the issues in artificial photosynthesis.请小伙伴们下载后给个好评！  |
