1. Site-isolated manganese carbonyl on bipyridine-functionalities of periodic mesoporous organosilicas: efficient CO₂photoreduction and detection of key reaction intermediates

Chem. Sci., 2017, Advance Article

DOI: 10.1039/C7SC03512H

European scientists have developed CO₂ reduction catalysts that exhibit high photoreduction activity in the presence of a photosensitizer. An earth abundant Mn complex was immobilized on bipyridine-periodic mesoporous organosilica (bpy-PMO) platform materials, and catalysed the reduction of CO₂ to CO and HCOOH with up to approximately 720 turnover number (TON). A range of reaction conditions were investigated, and the catalytic activity remained high when using simple photosensitizers such as organic dyes and Zn-porphyrin. These findings can be used to further develop efficient CO₂ photoreduction catalysts.

欧洲的科学家开发出一种在光敏剂存在下具有高光还原活性的二氧化碳（CO₂）还原催化剂。锰（Mn）元素在地壳中含量丰富，他们将Mn络合物固定于联吡啶-有序介孔有机硅（bpy-PMO）材料，可将CO₂还原成一氧化碳（CO）和甲酸（HCOOH），转换数（TON）高达近720。他们还对一系列的反应条件进行考察，反应即便使用简单的光敏剂，如有机染料和锌卟啉，仍然保持高催化活性。以上发现可用于进一步开发高效的CO₂光还原催化剂。

2. A matrix of heterobimetallic complexes for interrogation of hydrogen evolution reaction electrocatalysts

Chem. Sci., 2017, Advance Article

DOI: 10.1039/C7SC03378H

Researchers in the US and Taiwan investigated structure-function relationships of bioinspired HER electrocatalysts. The group generated a series of four bimetallics with gradually increasing nitrosylation, by incorporating non-innocent NO ligands on the acceptor units. The small differences in donor/acceptor units did not influence the overall structures but did affect catalytic performances. Incorporation of NO ligands resulted in energetically more accessible catalytic current, but at the expense of a stronger acid and a lower turnover frequency. Computational studies identified key features that may guide future synthetic targets.

美国与中国台湾的研究人员研究了析氢反应（HER）中所使用的仿生电催化剂的结构-功能关系。该团队通过在受体单元上掺杂非无辜的氮氧配体，合成了一系列共四种亚硝基化逐步增加的双金属催化剂。催化剂中供体/受体单元的微小差异并不会影响整体结构，但却对催化性能产生影响。氮氧配体的引入可以获得能量更为接近的催化电流，但却产生较强的酸和较低的转换率。计算研究得出的关键信息可能对未来的目标合成具有指导意义。
