1. Highly efficient halogen-free solvent processed small-molecule organic solar cells enabled by material design and device engineering

Energy Environ. Sci., 2017, Advance Article

DOI: 10.1039/C7EE00805H



Small molecule donor materials have emerged as promising candidates for organic solar cells (OSCs) due to their simple synthesis, well-defined molecular structures, high reproducibility, easy purification and high crystallinity. The reported efficient small molecule solar cells (SM-OSCs) commonly suffer from limitations of large energy loss (Eloss) and low charge carrier mobilities. Here, the authors develop and provide an interesting strategy via tactical material design and device engineering for developing high-performance SM-OSCs.


基于具有诸多优势,比如简单的合成方法、明确的分子结构、良好的可重复性、便捷的纯化过程和高结晶度,小分子给体材料在有机太阳能电池(OSC)中很有应用前景。之前报道的高效率小分子太阳能电池(SM-OSC)通常会受到高能量损失(Eloss)和低电荷载流子迁移率的限制。在本文中,四川大学彭强教授团队通过细致的材料设计和器件工程成功发展了一种开发高性能SM-OSC的有效策略。本文入选“2017 Energy and Environmental Science HOT articles”。

2. Ammonia Synthesis from N2 and H2O using a Lithium Cycling Electrification Strategy at Atmospheric Pressure

Energy Environ. Sci., 2017, Accepted Manuscript

DOI: 10.1039/C7EE01126A



Hot, fresh, novel strategy for the synthesis of ammonia using uses N2 and H2O at atmospheric pressure, as a potential alternative to the Haber process! The three steps of the demonstrated electrochemical lithium cycling process are LiOH electrolysis, direct nitridation of Li, and the exothermic release of ammonia from Li3N, which reproduces the LiOH, completing the cycle.


这篇新鲜出炉的论文报道了一种新颖的电化学锂循环策略,在常压下实现了由氮气和水合成氨。反应过程包括LiOH电解、Li的直接氮化、由Li3N放热释放氨并再生LiOH三个步骤并可循环进行,有望取代著名的哈伯法!本文入选“2017 Energy and Environmental Science HOT articles”。

1. Hybrid photocathode consisting of a CuGaO2 p-type semiconductor and a Ru(II)–Re(I) supramolecular photocatalyst: non-biased visible-light-driven CO2 reduction with water oxidation

Chem. Sci., 2017, 8, 4242-4249

DOI: 10.1039/C7SC00940B


Researchers in Japan have developed a new hybrid photocathode consisting of a CuGaO2 p-type semiconductor and a Ru(II)-Re(I) supramolecular photocatalyst. The photocathode displayed photoelectrochemical activity for the conversion of CO2 to CO. A photoelectrochemical cell encompassing this photocathode and a CoOx/TaON photoanode allowed the visible-light-driven catalytic reduction of CO2 using water as a reductant.


日本东京工业大学和京都大学的研究人员开发了一种由 CuGaO2 p型半导体和Ru(II)-Re(I)超分子光催化剂组成的新型复合光阴极材料,这种光阴极可以实现CO2到CO的光电化学转化。包含该光阴极和CoOx/TaON光阳极的光电化学电池能在可见光的照射下利用水来实现CO2的催化还原。

2. Enhancing the Reactivity of Nickel(II) in Hydrogen Evolution Reactions (HER) by β-Hydrogenation of Porphyrinoid Ligands

Chem. Sci., 2017, Accepted Manuscript

DOI: 10.1039/C7SC02073B



Scientists in Beijing report for the first time that ß-hydrogenation of porphyrin enhances electrocatalytic HER reactivity using nickel porphyrinoids. DFT calculations suggest that ß-hydrogenation renders more electron density localized on the Ni centre and hence, generates a highly reactive Ni hydride intermediate. The findings have the potential for the further design of metal molecular catalysts.


北京大学张俊龙、王炳武、郑捷等科研人员首次报道了利用异卟啉镍络合物进行卟啉的β-氢化过程来增强电催化析氢反应(HER)的活性。密度泛函理论计算表明,β-氢化使镍中心的定域电子密度升高,因而产生高反应活性的氢化镍中间体。这一发现有望用于进一步设计金属分子催化剂。
