“…From Figure d, it is noticeable that it keeps up 76% of its initial specific discharge capacity after 99 cycles. The specific discharge capacity of the CsPbBr 3 perovskite electrode is compared with those of the recently reported articles in Table . ,,,− ,, It is worth mentioning that not all perovskite materials are used in LIBs and fabricated energy storage devices using these perovskites as an anode are not measured under the same conditions (morphology and size of the perovskites, electrolyte, etc.). It is evident that the CsPbBr 3 perovskite anode for LIBs reported in the current work shows good specific discharge capacity.…”

Whenever the phrase metal halide perovskites is referred, we generally think of the optoelectronic applicability. Going beyond this, here, we report the usage perspective of CsPbBr3 as an active anode material in Li-ion batteries. To investigate its electrochemical behavior as an anode, half and full Li-ion batteries are fabricated by using a gel polymer electrolyte. The fabricated half-cell exhibits specific discharge capacities of ∼376, 261, 202, and 142 mA h g–1 at current densities of 30, 60, 150, and 200 mA g–1, respectively. The cell retains 79% of its initial specific discharge capacity after 100 cycles at a current density of 60 mA g–1. Any severe alteration or re-arrangement of the crystal structure in the Li+ intake/release process during the electrochemical cycling also suggests the notable stability of the fabricated CsPbBr3 perovskite. Experimental results are further corroborated via density functional theory. This work may endow a new avenue for the realization of other perovskite-based Li-ion batteries and motivates the researchers for possible integration of Li-ion batteries and solar cells and thereby envisages their potential as photobatteries.

“…The diameter of the MN-NMN09/NF structure is ≈1-2 μm. [33,34] To understand the effect of nitridation on the morphology, the Mo-Ni09 precursor was first calcined at high temperature under argon (Ar, 650 °C, 2 h) atmosphere, named Mo-Ni09-Ar. Its SEM image revealed that the "sword-head" morphology of the precursor was not maintained but exhibited rough surfaces (Figure S6, Supporting Information).…”

“…After hydrothermal reaction, the Ni-Mo precursors were treated in NH 3 atmosphere at 650 °C for 2 h, and porous sword-head-like structures assembled into flower-like morphology of the Mo 2 N-Ni 3 Mo 3 N with rough surfaces were formed on the NF (denoted MN-NMN09/NF) (Figure1c, inset and FigureS5b, Supporting Information). The diameter of the MN-NMN09/NF structure is ≈1-2 μm [33,34]. To understand the effect of nitridation on the morphology, the Mo-Ni09 precursor was first calcined at high temperature under argon (Ar, 650 °C, 2 h) atmosphere, named Mo-Ni09-Ar.…”

Realizing efficient electrocatalysts is a stepping stone toward achieving high‐performance alkaline water/seawater electrolysis, but remains a crucial challenge. Herein, heterogeneous Mo2N/Ni3Mo3N electrocatalysts on nickel foam (denoted MN‐NMN/NF) that is stable and active for the hydrogen evolution reaction (HER) in both alkaline water/seawater are demonstrated. The optimized MN‐NMN09/NF achieves an ultralow HER overpotential of 11 mV@10 mA cm−2 in 1.0 m KOH electrolyte, which is not only superior to the benchmark Pt/C catalysts but also the best reported ever among NiMo‐based electrocatalysts in an alkaline environment. Successively, the optimized MN‐NMN09/NF electrocatalyst can drive HER current densities of 10 and 500 mA cm−2 using low overpotentials of 9.37 and 123 mV in 1.0 m KOH seawater electrolyte, which remains durable after 120 h long‐term electrolysis at a constant current density of 500 mA cm−2. In situ Raman analysis reveals that the enhanced performance is attributed to the accelerated H2O adsorption and OH dissociation processes on the MN‐NMN surfaces. Theoretical analysis further confirms that rapid H2O adsorption‐dissociation kinetics and H adsorption‐conversion kinetics on the Ni3Mo3N/NiOOH and Ni3Mo3N/MoOx surfaces result in boosted HER capability. This work depicts a significant potential for designing stable and efficient hydrogen production electrocatalysts for both alkaline water and seawater electrolysis.

“…In terms of materials, methylammonium lead iodide (CH3NH3PbI3 or MAPbI3), a perovskite-like organic-inorganic metal halide, has emerged as a viable low-cost material for nextgeneration high-efficiency perovskite solar cells [18]. Furthermore, the sensitivity of perovskite materials allows this disadvantage to be turned into an advantage [19]. As far as we know, this is the first sensor system using MAPbI3 as a modifier that has appropriate results for measuring one of the main parts of the human diet.…”

A novel and sensitive electrode was suggested for the rapid determination of ascorbic acid (AA) using a glassy carbon electrode (GCE) modified with synthesized MAPbI3 and L-cys (L-cys/MAPbI3/GCE). Determination of ascorbic acid as an important component of the human diet due to help in decreasing blood pressure and improving endothelial function is crucial. The synthesized MAPbI3 was characterized by different methods, including transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), and X-ray diffraction (XRD). The fabricated electrode exhibited superior electrical conductivity and fast electron transfer kinetics. The results illustrated that the developed electrode had an outstanding electrocatalytic activity towards the oxidation of AA in 0.1 M Britton–Robinson buffer(B-R) as a supporting electrolyte. The modified electrode demonstrated a linear range in differential pulse voltammetry of 0.02–11.4 µM with a low detection limit of 8.0 nM for ascorbic acid. It can be stated that the proposed sensor can be successfully applied to the determination of ascorbic acid in human plasma samples.
