Plasmonic nanostructures which are characterized by strong light absorption through the excitations of collective free electron oscillations is known as surface plasmon resonance (SPR). Such nanostructures have recently shown a great potential for solar energy conversion.
　　Although the plasmonic hot electrons in water reduction have been extensively studied, exactly how the plasmonic hot holes participate in the water splitting reaction has not yet been well understood. In particular, it's still illusive that where the plasmonic hot holes participate in water oxidation.
　　Recently, the research group led by Prof. LI Can in Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), identified the water oxidation reaction sites in plasmonic photocatalyst Au/TiO2 and fabricated a visible-light-induced overall water splitting system based on surface plasmon effect. This work has been published in J. Am. Chem. Soc. (DOI: 10.1021/jacs.7b04470).
　　They clearly demonstrated that the plasmon-induced water oxidation reaction takes place at the reaction sites localized at the interface between Au and TiO2. The reaction sites are positioned by photodeposition together with element mapping by electron microscopy, while the distribution of holes is probed by surface photovoltage imaging with Kelvin probe force microscopy. Density functional theory also corroborates these findings by revealing the promotion role of interfacial structure (Ti-O-Au) for oxygen evolution.
　　Gold-semiconductor interface is identified as reaction sites for water oxidation
　　On the basis of this found, they successfully assembled an artificial Z-scheme photosynthesis system with redox ions for overall water splitting under visible light illumination. What’s more, this group even developed an all-solid plasmon-induced Z-scheme system for overall water splitting, very recently. This is more important and challenge to achieve overall water splitting in an all-solid artificial photosynthesis system. This work has been published in J. Catal..

　　From May 2017, four DeNOx industrial units have been successfully carried out in Hebei Donghai Steel group Co. Ltd (flue-gas flux: 250000Nm3/hr), Xuzhou Dongxing Energy Co. Ltd (flue-gas flux: 300000Nm3/hr), Tangshan Dafeng Coking Co. Ltd (flue-gas flux: 170000Nm3/hr), Qian’an Jiujiang Coal Storage and Transportation Company (flue-gas flux: 250000Nm3/hr) for removal of NOx from coke oven flue gas. These units were all loaded with high-efficiency low-temperature DeNOx catalysts developed by DNL0901.
　　 
　　 
　　Since 2013, DNL0901 has focused on the denitrification of coke oven flue gas, and developed an efficient low-temperature SCR catalyst for the denitrification of coke oven flue gas.
　　In 2015, DNL0901 jointed with Jiangsu WOTE environmental protection equipment Engineering Co. Ltd and Jiangsu Yizhou Coking Co. Ltd to establish the first low-temperature DeNOx industrial demonstration unit for reduction of NOx emissions from the 3# coke oven in Jiangsu Yizhou Coking Co. Ltd, and in 2016 Jiangsu Yizhou Coking Co. Ltd continued to use our technology for the denitration construction of the remaining three coke oven.
　　These four sets of denitration device have run stably in more than one year and the stable operation of these four sets has played a good demonstration role in the process of flue gas denitration in the coking industry of China.
　　This year, our denitration technology continues to be widely used in the coking industry. Since the commissioning of these four units, the outlet nitrogen oxide concentration of the denitrification unit can be less than 100 mg/m3, which shows very good denitrification effect, and ensures that the nitrogen oxides of the coke oven flue gas meet the standard limit.

　　In the last few years, the flexible electrodes with high active materials loadings have attracted extensive attentions due to the increasing development of flexible and wearable electronic devices.
　　Generally, only the flexible 1D and 2D materials, such as carbon nanotube, carbon fiber, and graphene which can be intertwined or laminated with each other, have been applied as the body materials of flexible electrodes successfully. The 0D nano particles which are more diverse and cost-effective cannot be used as the main materials of the flexible electrodes yet.
　　The research group of Energy Storage Technology Research Department, which is led by ZHANG Huamin, LI Xianfeng and ZHANG Hongzhang from Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS), has firstly prepared the flexible electrodes boased on 0-D nanoparticle with controllable shapes successfully. The preparation is via coupling phase inversion and freeze-drying methods. This work has been published on the Nano energy (Nano energy, 2017, 39, 418-428).
　　Schematic illustration of the formation process of as-prepared electrode and the assembled Li-S battery
　　This flexible and shapeable electrode presents an ultra-high sulfur loading which is 24 mgcm-2. After 100 cycles, the initial areal capacity and the capacity retention can achieve to 27.1 mAhcm-2 and 64.1%, respectively.
　　In addition, Li-ion battery electrodes based on 17 mgcm-2 0-D Li3V2(PO4)3(LVP) electrode could also be obtained. It can achieve an excellent C-rate performance and present good cycling stability, which are 94 mAhg-1 at 5C and nearly 100% capacity retention at 1C during 100 cycles.
　　This study further broadens the materials options for flexible electrodes and creates the conditions for the application of 0-D nanomaterials in flexible electrochemical energy storage devices.
