A novel photoelectrochemical (PEC) sensor based on a nickel phthalocyanine-based metal organic framework (NiPc–Ni MOF) was prepared and used to detect Curcumin. The photosensitive material NiPc–Ni MOF was synthesized and characterized via scanning electron microscopy, transmission electron microscopy, and X-ray diffraction. Under white light irradiation, the NiPc–Ni MOF composite modified indium tin oxide glass electrode showed a good photocurrent response to the detection of Curcumin. The experimental conditions of a light source, pH, bias voltage, modifier concentration, and coating amount were optimized. The improved PEC sensor showed a linear range of 0.0025–16 μM and a detection limit of 0.8 nM. Moreover, the PEC sensor exhibited good stability, selectivity, and reproducibility. Finally, the PEC sensor was used to detect Swisse Curcumin tablets with satisfactory results. The method presented in this study is a new strategy for detecting Curcumin.

Nickel phthalocyanine (NiPc) can be at first glance a compelling catalyst for CO 2 reduction reaction (CO 2 RR) because of its Ni–N 4 site. Unfortunately, the pristine NiPc possesses a low catalytic activity resulting from the poor CO 2 adsorption and activation capabilities of the electron-deficiency Ni site. Herein, we develop nickel polyphthalocyanine (NiPPc) with extended conjugation to tailor the electronic density at the Ni active site. The enlarged π conjugation of NiPPc evokes the d-electrons localization, increasing the electronic density at the Ni site, which enhances its CO 2 adsorption and activation. Consequently, NiPPc supported on carbon nanotubes (NiPPc/CNT) in a flow cell delivers an excellent activity of −300 mA cm −2 for CO 2 RR with the CO selectivity of 99.8%, which is much higher than that of NiPc dispersed on carbon nanotubes. NiPPc/CNT exhibits an outstanding stability for CO 2 RR of more than 30 h at a current density of −100 mA cm −2 with an ultrahigh selectivity for CO, exceeding 99.7%. This work showcases a new way of tuning the electronic density of catalytic sites.

Developing a robust catalyst for CO 2 reduction reaction (CO 2 RR) is critical to achieving a closed carbon cycle. Yet, the process of CO 2 RR still faces enormous challenges, in part because of the lack of highly active, stable, as well as cost-effective electrocatalysts. In this work, we reported an effective and sample strategy to immobilize nickel phthalocyanine (Ni-Pc) molecules on the fruit-peel-derived carbon framework surface (denoted as Ni-Pc/CF and carbon framework denoted as CF) with exceptional CO production performances. Dispersed Ni-Pc molecules on the carbon materials are verified by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and Raman measurements. The obtained Ni-Pc/CF catalyst shows that the high faradaic efficiency (FE) exceeds 95.0 % over a potential of −0.7 to −0.9 V ( vs reversible hydrogen electrode (RHE), V RHE ), the maximum FE (99.1 %) can close to 100 % at −0.8 V, and the excellent stability over a 10 h reaction period. This work offers valuable insights into the immobilization of stabilized, highly dispersed molecule catalysts on carbon materials surfaces for selective reduction of CO 2 to CO.

In this article, the fabrication and characterization of a photoelectrochemical (PEC) rifampicin sensor based on graphene oxide grafted with Ni tetraamino phthalocyanine was described, which presents an excellent PEC activity, sensitivity, and material stability. The synthesized graphene oxide grafted with Ni tetraamino phthalocyanine was characterized using ultraviolet–visible (UV–vis), Fourier transform infrared (FTIR), scanning electron microscopy (SEM), and transmission electron microscopy (TEM) analyses. Specifically, detection for rifampicin was based on the reduction of photocurrent caused by binding of the analyte to the sensing electrode surface. The fabricated sensor was characterized in a broad linear response range (0.025–71.3 μM) and with a low detection limit (2.5 nM), outperforming the previously reported sensors and thus being well suited for quality control and other applications, as confirmed by successful real-life sample testing.

The efficiency of perovskite solar cells (PSCs) has increased from around 4% to over 22% following a few years of intensive investigation. For most PSCs, organic materials such as 2,2′,7,7′-tetrakis( N,N -pdimethoxyphenylamino)-9,9′-spirobifluorene (spiro-OMeTAD) are used as the hole transporting materials (HTMs), which are thermally and chemically unstable and also expensive. Here, we explored nickel phthalocyanine (NiPc) as a stable and cost-effective HTM to replace the conventionally used spiro-OMeTAD. Because of its high carrier mobility and proper band alignments, we achieved a PCE of 12.1% on NiPc based planar device with short-circuit current density ( J sc ) of 17.64 mA cm −2 , open circuit voltage ( V oc ) of 0.94 V, and fill factor (FF) of 73%, outperforming the planar device based on copper phthalocyanine (CuPc) that is an outstanding representative of metal phthalocyanines (MPcs) reported. Moreover, the device with NiPc shows much improved stability compared to that based on the conventional spiro-OMeTAD as a result of NiPc’s high stability. Photoluminescence (PL) and Impedance spectroscopy analysis results show that thermally deposited NiPc has good hole-extraction ability. Our results suggest that NiPc is a promising HTM for the large area, low cost and stable PSCs.

The heterogenized metallomacrocycles with atomically dispersed active sites are identified as the promising candidates for electrocatalytic CO 2 reduction reaction (CO 2 RR), where their unique heterointerface with interaction between sp 2 carbon and macrocyclic molecules is important but remains vague. Herein, based on well-structured nickel phthalocyanine and porphyrin with the same functional groups (MeNiPc and MeNiPp), the influences of heterointerfacial effect on catalytic performances are systematically disclosed. Through the molecular structure-induced self-adaptive adsorption with optimized heterointerfacial distance, MeNiPc/graphene reveals a high CO Faradaic efficiency of ~99% in a wide potential window, greatly outperforming the MeNiPp/graphene counterpart (≤29.6%). Detailed measurements and theoretical calculations decipher that the higher CO 2 RR activity of MeNiPc/graphene is attributed to the unique electronic structures of the Ni-N 4 configurations suitable for well-suited heterointerfacial charge transfer and rapid CO desorption. Additionally, the extended research confirms the universality of heterointerface engineering on boosting the catalytic performances.

For solving the problems of high solubility in electrolytes, poor conductivity and low active site utilization of organic electrode materials, in this work, 1,4,5,8-naphthalenetetracarboxylic dianhydride (NTCDA) grafted nickel phthalocyanine (TNTCDA-NiPc) was synthesized and used as an anode material for lithium ion batteries. As a result, the dispersibility, conductivity and dissolution stability are improved, which is conducive to enhancing the performance of batteries. The initial discharge capacity of the TNTCDA-NiPc electrode is 859.8 mA h g−1 at 2 A g−1 current density, which is much higher than that of the NTCDA electrode (247.4 mA h g−1). After 379 cycles, the discharge capacity of the TNTCDA-NiPc electrode is 1162.9 mA h g−1, and the capacity retention rate is 135.3%, which is 7 times that of the NTCDA electrode. After NTCDA is grafted to the phthalocyanine macrocyclic system, the dissolution of the NTCDA in the electrolyte is reduced, and the conductivity and dispersion of the NTCDA and phthalocyanine ring are also improved, so that more active sites of super lithium intercalation from NTCDA and phthalocyanine rings are exposed, which results in better electrochemical performance. The strategy of grafting small molecular active compounds into macrocyclic conjugated systems used in this work can provide new ideas for the development of high performance organic electrode materials.

In this study, a novel electrochemical sensor was designed to detect luteolin (Lu) with the composite of gold nanoparticles and nickel phthalocyanine-based 2D conductive metal-organic frameworks (Au NPs@NiPc-Cu MOFs) for the first time. The NiPc-Cu MOFs exhibit excellent conductivity, large specific surface area, and porous structure, which can accelerate the mass transfer process of target molecules. To further improve the sensitivity of the sensing platform, Au NPs with outstanding conductivity were introduced to the surface of NiPc-Cu MOFs to prepare Au NPs@NiPc-Cu MOFs. The synergistic effect of NiPc-Cu MOFs and Au NPs endows the sensor with excellent electrocatalytic performance and outstanding sensitivity. Under optimal conditions, the electrochemical sensor has a wide linear range (0.1–40 μM). Moreover, the prepared sensor possesses good stability and anti-interference ability. This method does not require complicated sample pretreatment, simple operation, and short detection time, which can provide a new method for the rapid detection of Lu.

The sluggish oxygen evolution reaction (OER) attracts increasing attention for the storage and/or conversion of clean energy. However, the whole design of precursor and product is studied a few for efficient photocatalytic and electrocatalytic water oxidation . Here, we report the large-scale synthesis of one-dimensional (1D) nanohybrids (NHs) of 50-nm nickel perylene diimide (Ni-PDI) nanowires loading iron hydroxide (Fe(OH) 3 ) nanoparticles through one-step hydrothermal reaction . The Fe(OH) 3 @Ni-PDI NHs as OER photocatalyst possess the super activity, even high electrocatalytic performance after pyrolysis . Under visible light (λ > 420 nm), the photocatalytic oxygen evolution rate of 22,000 μmol g −1 h −1 can be achieved via the synergy between 1D Ni-PDI nanowires and in-situ generated iron (oxy)hydroxide as cocatalyst . Through pyrolysis of 1D Fe(OH) 3 @Ni-PDI NHs, the NiFe nanoparticles covered by NiFe 2 O 4 layer can be synthesized on 30-nm nitrogen-doped carbon nanowires (NiFe/NiFe 2 O 4 @NC). After optimizing the mole ratio of nickel to iron atoms (2:1) and pyrolysis temperature (800 °C), as-obtained sample exhibits the OER activity with the overpotential of 256 mV at 10 mA cm −2 and Tafel slope of 40 mV dec −1 in 1.0 M KOH. The work provides a universal strategy to design 1D nanostructure for efficient OER catalysis.

Curcumin is extensively utilized across various domains including the food, pharmaceuticals, and chemical industries. However, excessive curcumin intake may induce tissue necrosis, thereby posing a substantial threat to human health, making rapid and precise detection of curcumin levels paramount. Here, tetranitro nickel phthalocyanine (NiPc) was synthesized via a solid-phase method. Subsequently, it underwent an azo condensation reaction with p-phenylenediamine (PPDA) under the assistance with potassium hydroxide. This process was used to fabricate a nickel phthalocyanine-based covalent organic framework material (PPDA-NiPc COF). Herein, NiPc serves as the acceptor unit (A) with high electron-accepting capability, while PPDA functions as the donor unit (D) to provide electrons. The D-A architecture established through imine bond formation, which significantly enhances photogenerated charge carrier separation and transfer. The photoelectrochemical sensor constructed based on two-dimensional COF exhibits remarkable sensitivity for curcumin detection. It demonstrates a favorable linear response within the concentration range of 0.05 to 50 μM, with a detection limit as low as 1.46 nM. Moreover, this detector possesses superior stability and reproducibility and enables accurate quantification curcumin in real samples. This study not only expands COF material applications in photoelectrochemical sensing but also provides a novel strategy for detecting curcumin.

Herein, a novel composite solid-state polymer electrolytes (CSEs) was regulated by introducing CoNi-MOF (Metal-organic framework) @NiPc (Nickel phthalocyanine) nanofiller (CMN) into PEO (polyethylene oxide) matrix. In this novel system, the NiPc uniformly wrapped around the surface of MOF through hydrogen bond bridging, avoiding the agglomeration of the MOF particles. The chemisorption between Ni 2+ in NiPc and the O atoms in the bis(triffuoromethanesulfonyl)imide anion (TFSI − ) restricted the mobility of the anions within the CSEs, which improved the release of Li + ions from the NiPcLi. In addition, the π-π conjugated groups present in NiPc facilitated a spontaneous formation of additional lithium ion transport channels within the PEO (polyethylene oxide) matrix. The novel CSEs displayed a Li + transference number of 0.79 and ionic conductivity (2.65 × 10 −4 S cm −1 ). The nitro groups at the peripheral position of NiPc acted as intermediaries that firmly combined the PEO and MOF via the formation of mutual hydrogen bonds, avoiding the shedding of active materials from the base polymer and ensuring long-term stability. Moreover, the decrease in the HOMO (highest occupied molecular orbital) energy level of the obtained CSEs indicated an improvement in its ability to resist oxidation. Consequently, an Li//Li(Ni 0.8 Co 0.1 Mn 0.1 O 2 ) (NCM811) high-voltage battery containing the obtained CSEs displayed good performance. The Li + transport and enhanced electrochemical stability window of the MNPL were further revealed by theoretical calculations. Overall, these results demonstrated a new strategy for the design and preparation of high-performance CSEs through the introduction of multifunctional MPc (Metal phthalocyanine) for solid-state rechargeable Li-metal batteries.

A porous MA–VA–PcNi polymer was prepared by grafting nickel phthalocyanine (PcNi) onto the main chain of a maleic anhydride–vinyl acetate (MA–VA) polymer, and an MA–VA–PcNi electrode is prepared by electrospinning technology to inhibit the agglomeration of the active powder effectively, which produces spherical particles with a diameter of 100–300 nm. The synthesized MA–VA–PcNi polymer is used as the anode for lithium-ion and sodium-ion batteries, exhibiting excellent energy storage behaviors. The MA–VA–PcNi/Li battery displays a high capacity of 610 mA h g−1 and can still remain at 507 mA h g−1 with a retention rate of 83.1% after 400 cycles at a current density of 200 mA g−1. Even at a high current density of 2 A g−1, the specific capacity can remain at 195 mA h g−1. In addition, the MA–VA–PcNi/Na battery displays a high capacity of 336 mA h g−1 and can still remain at 278 mA h g−1 with a retention rate of 82.7% after 400 cycles at a current density of 100 mA g−1. A high specific capacity of 164 mA h g−1 can also be achieved at a high current density of 1 A g−1. After nickel phthalocyanine (PcNi) was grafted onto the MA–VA polymer, aggregation between phthalocyanine rings was effectively prevented, and this exposes more active sites. At the same time, the spherical particles obtained by electrospinning technology further improve the dispersion and increase the number of active sites of the active materials. Finally, the electrode materials show excellent energy storage behavior for lithium-ion and sodium-ion batteries, which provides a new idea for designing high-performance energy storage materials for organic electrodes.
