Chem. Mater.最新綜述: 基于仿光合作用的半導(dǎo)體納米線——楊培東出品
|
|||||||||
|
納米線可以被定義為一種具有在橫向上被限制在100納米以下(縱向沒有限制)的一維結(jié)構(gòu)。懸置納米線指納米線在真空條件下末端被固定。典型的納米線的縱橫比在1000以上,因此它們通常被稱為一維材料。根據(jù)組成材料的不同,納米線可分為不同的類型,包括金屬納米線,半導(dǎo)體納米線和絕緣體納米線。納米線均在實(shí)驗(yàn)室中生產(chǎn),截至2014年尚未在自然界中發(fā)現(xiàn)。納米線可以由懸置法、沉積法或者元素合成法制得。懸置納米線可以通過對(duì)粗線的化學(xué)刻蝕得來,也可以用高能粒子(原子或分子)轟擊粗線產(chǎn)生。 Semiconductor Nanowires for Artificial Photosynthesis 共8頁 引文82篇 Chong Liu,†,§ Neil P.

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.請(qǐng)小伙伴們下載后給個(gè)好評(píng)! |
