Electrochemical synthesis of ammonia via the nitrate reduction reaction (NO3RR) has been intensively researched as an alternative to traditional Haber–Bosch process. Most research focuses on low concentration range representative level in wastewater, leaving high range, which exists nuclear and fertilizer wastes, unexplored. The use a concentrated electrolyte (≥1 M) for higher rate production is hampered by poor hydrogen transfer kinetics. Herein, we demonstrate that cocatalytic system...
A common challenge for electrochemical ammonia synthesis in an aqueous phase is the consumption of Faradaic charge by competing hydrogen evolution reaction (HER), which reduces efficiency desired conversion, i.e., nitrate reduction (NO3RR) to ammonium. This problem particularly severe when a single-phase catalyst operated at high current limits, thus cocatalyst system that works synergistically acquisition and deoxygenation needed promote NO3RR over HER. Herein, we select well-known HER Mo2C...
Abstract A power conversion efficiency (PCE) as high 19.7% is achieved using a novel, low‐cost, dopant‐free hole transport material (HTM) in mixed‐ion solution‐processed perovskite solar cells (PSCs). Following rational molecular design strategy, arylamine‐substituted copper(II) phthalocyanine (CuPc) derivatives are selected HTMs, reaching the highest PCE ever reported for PSCs employing HTMs. The intrinsic thermal and chemical properties of CuPcs result with long‐term stability...
Electrochemical redox flow desalination is an emerging method to obtain freshwater; however, the costly requirement for continuously supplying and regenerating species limits their practical applications. Recycling of spent lithium-ion batteries a growing challenge sustainable utilization. Existing battery recycling methods often involve massive secondary pollution. Here, we demonstrate system couple with lithium recovery from batteries. The spontaneous reaction between cathode material...
Flavonoids are essential nutrient compounds in kiwifruit, yet the specific regulatory mechanism governing their biosynthesis remains poorly understood. In this study, we identified an R2R3-MYB transcription factor (TF), AcMYB22, associated with flavonoid kiwifruit. Two alleles of AcMYB22 were isolated: AcMYB22-1 is exclusively present cultivar "Hongyang", while both and AcMYB22-2 its mutant "H-16", nine single nucleotide polymorphisms. Overexpression kiwifruit resulted enhanced yellow flesh...
Abstract Dopamine (DA) and uric acid (UA) are biomolecules of great consideration that coexist in human body. It is essential challenging to detect them simultaneously with high sensitivity. This paper reports a novel electrochemical biosensor based on the nanocomposites cobalt phthalocyanine (CoPc) anchored graphene quantum dots (GQDs) for DA UA detection. The GQDs incorporation CoPc nanorods partial end stretching significantly enhances electrocatalytic activity promotes electron transfer...
Efficient and stable hole‐transporting materials (HTMs) are necessary for perovskite solar cells (PSCs) with excellent efficiency long‐term stability. Here, two A 3 B‐type metal phthalocyanine (MPc) compounds prepared as dopant‐free HTMs conventional n‐i‐p structured PSCs. Mono‐ n ‐butyl‐substituted zinc hexamethyl‐mono‐n‐butyl‐substituted (Me 6 Bu‐ZnPc) synthesized through ring‐expansion method, their exact structures characterized using nuclear magnetic resonance mass spectroscopy. The...
We demonstrate a molecular design strategy to enhance the efficiency of phthalocyanine (Pc)-based hole-transporting materials (HTMs) in perovskite solar cells (PSCs). Herein, two titanyl (TiOPc) derivatives are designed and applied as dopant-free HTMs planar n-i-p-structured PSCs. The newly developed TiOPc compounds possess eight n-hexylthio groups attached either peripheral (P-SC6-TiOPc) or nonperipheral (NP-SC6-TiOPc) positions Pc ring. Utilizing these PSCs with mixed cation...
Main observation and conclusion In this paper, pristine cobalt(II) phthalocyanine (CoPc) non‐peripheral octamethyl substituted CoPc (N‐CoMe 2 Pc) are the focus of electrochemical investigation. N‐CoMe Pc nanorods (NR) were synthesized by a facile precipitation process from sublimated bulk powders their properties explored. Due to large specific surface area, capacitance performance was significantly higher than that powder sample. exhibited better pseudocapacity compared with NR, which is...
The molecular organic Lewis acid bis(pentafluorophenyl)zinc [Zn(C 6 F 5 ) 2 ] is reported as an efficient p‐type dopant for poly(3‐hexylthiophene‐2,5‐diyl) (P3HT), to be used hole‐transporting material (HTM) in perovskite solar cells (PSCs) the first time. To date, most PSCs use lithium bis(trifluoromethane)sulfonimide salt (LiTFSI) and 4‐ tert ‐butylpyridine ( t BP) standard additives HTMs. However, such dopants can induce deleterious effects on device stability. Herein, effect of...
