Nickel (II) Phthalocyanine-Tetrasulfonic Acid Tetrasodium Salt as a High-Performance Organic Anode for Ion Battery

Abstract

Nickel (II) phthalocyanine-tetrasulfonic acid tetrasodium salt, with super chemically stability and high electrochemical capacity, is proposed as novel organic anodes. Ex situ FTIR patterns evidence the bonding effects between positively charged Li ions and negatively charged Pc molecules, which greatly benefits the stable reversibility and real capacity of TsNiPc. To conquer the poor conductivity of the organic molecular, graphene oxide/TsNiPc composites have been fabricated through a facile hydrothermal freezedrying method. The capacity of TsNiPc@GO was maintained at 455 mAh g −1 after 100 cycles, when the capacity of 99.8 mAh g −1 from carbon was subtracted, the true capacity of TsNiPc was 335.2 mAh g −1 , which was superior to many organic anodes.

Facile Preparation of Self-Assembled Black Phosphorus-Dye Composite Films for Chemical Gas Sensors and Surface-Enhanced Raman Scattering Performances

“…From Figure j, it could be seen that the characteristic peaks of BP appeared on three composite films with a slight movement, which might be attributed to the different aggregation states of the composite films. For Figure j2,3, the bands at around 600–690 cm –1 are assigned to the C–N, Ni–N, and CN, which correspond to the A 1g modes. , In addition, the highest intensity features of TsNiPc can be found at 1340 and 1558 cm –1 , which is caused by CCC (A 1g ) and C–N (B 1g ) and CNCCC (B 1g ), respectively. A similar situation can be used to explain the Raman spectrum of the BPNS-PEI-TsCuPc film. , Moreover, the strong bonds at 1478 and 1538 cm –1 correspond to the ν 3 and ν 2 of TPPS, as shown in Figure j4 .…”

Analysis of the optical and electronic characteristics of Al/NiPc complex/p-Si diode

“…In this study, nickel phthalocyanine complex compound with molecular formula C 32 H 12 N 8 Na 4 NiO 12 S 4 (NiTsPc), which was obtained from Sigma-Aldrich company, was used. The molecular structure of the NiTsPc compound are shown in figure 1(a) [37][38][39]. The NiTsPc stock solution with a concentration of 0.00357 mol l −1 .was created by adding 0.035 g NiTsPc powder to 10 ml 18 MΩ resistive de-ionized water.…”
