| 4 | Vertical 3D Nanostructures Boost Efficient Hydrogen Production Coupled with Glycerol Oxidation Under Alkaline Conditions显示文摘Hydrogen production from electrolytic water is an important sustainable technology to realize renewable energy conversion and carbon neutrality.However,it is limited by the high overpotential of oxygen evolution reaction(OER)at the anode.To reduce the operating voltage of electrolyzer,herein thermodynamically favorable glycerol oxidation reaction(GOR)is proposed to replace the OER.Moreover,vertical Ni O flakes and NiMoNH nanopillars are developed to boost the reaction kinetics of anodic GOR and cathodic hydrogen evolution,respectively.Meanwhile,excluding the explosion risk of mixed H_2/O_(2),a cheap organic membrane is used to replace the expensive anion exchange membrane in the electrolyzer.Impressively,the electrolyzer delivers a remarkable reduction of operation voltage by 280 mV,and exhibits good long-term stability.This work provides a new paradigm of hydrogen production with low cost and good feasibility. | Shanlin Li Danmin Liu Guowei Wang Peijie Ma Xunlu Wang Jiacheng Wang Ruguang Ma | 2023 | Nano-Micro Letters2023，15，10： | 0 |
| 5 | A Bipolar and Small Singlet-Triplet Splitting Energy Host with Triplet Energy Lower Than a Blue Phosphor for Phosphorescent OLEDs in Panchromatic Range显示文摘A bipolar host material, 2,4,6-tris(3-(carbazol-9-yl)phenyl)-triazine (TCPZ), was synthesized according to re-ported method. Due to the higher triplet energy compared to green and red phosphors, TCPZ is suitable to host themin phosphorescent organic light-emitting diodes (PhOLEDs). Although the triplet of TCPZ is slightly lower than acommon blue phosphor, good blue PhOLEDs using TCPZ as the host were successfully demonstrated in this work.By low temperature emission measurement, it was found that the energy splitting between the singlet and triplet ofTCPZ is as small as 0.24 eV. Therefore, thermal activated energy transfer from triplet to singlet in the host TCPZ isexpected to occur, which can be afterwards efficiently transferred to the blue phosphor, hence enabling it to hostblue phosphor. As a result, TCPZ can be used as host for phosphors in panchromatic range. Additionally, sin-gle-carrier devices clearly prove its good bipolar transport feature, beneficial to device performance. By usingTCPZ as a host, high performance deep-red, green and blue PhOLEDs have been achieved, with maximum effi-ciencies of 9.3 cdoA 1 (13.2%), 81.3 cd·A 1 (23.1%) and 17.03 cd·A^-1 (10.4%), respectively. | Chuanjun Wang Gaowen Liu Shaojie Liu Xunlu Zhang Changjin Ou Lu Wang Wei Sun Baoxiu Mi Juan Song Zhiqiang Gao | 2016 | Chinese Journal of Chemistry2016，34，8： | 0 |
