The corrosion inhibition efficiency of 1-hexylpyridinium bromide for carbon steel in molar hydrochloric acid has been investigated by gravimetric, linear polarization, electrochemical impedance spectroscopy and scanning electron microscopy techniques.
A highly selective and sensitive dopamine electrochemical sensor based on nitrogen-doped graphene quantum dots-chitosan nanocomposite-modified nanostructured screen printed carbon electrode is presented, for the first time. Graphene dots were prepared via microwave-assisted hydrothermal reaction of glucose, nitrogen doping was realized by introducing ammonia in mixture. Chitosan incorporation played a significant role towards selectivity hindering ascorbic acid interference enlarging peak...
In this work, we report on the design of an enzyme-less sensitive and selective electrochemical electrode for ascorbic acid (AA) detection using a modified screen-printed melanin-like nanoparticles (Mel-NPs). Cyclic voltammetry shows that melanin-modified exhibits high electrocatalytic activity acid. The serve as shuttle to transport electrons from surface. is endowed with large dynamic window ranging 5 500 ppb. quantification limits were estimated be 0.07 0.23 ppb, respectively. was...
Hydrogen is the kind of pure, renewable energy that required for world to begin relying less and on fossil fuels it currently consumes. The production hydrogen by electrocatalytic water splitting deemed be preferable consumption generation clean reliable energy. A catalyst's ability catalyze significantly influenced number exposed active sites in catalyst. Thus, purpose current work offer a simple inexpensive strategy synthesize double non-noble metal catalyst VSe2/MoSe2 via one-step...
Recently, tungsten disulfide (WS2) has received considerable attention in aspects of electrocatalytic oxygen evolution reactions (OER). However, due to the restricted number active sites, WS2 nanoflower a high overpotential OER. Thus, we provide herein doping approach for with non-noble aluminum (Al) metal increase sites an effort enhance OER activity WS2. The positive effect Al-doping on material results lower operating overpotential. In comparison undoped WS2, skeleton-like structure (0.04...
To progress the clean hydrogen-gas-based energy economy, there is a demand for cost-effective, highly efficient catalysts to facilitate hydrogen evolution reaction process (HER). Due amazing catalytic capabilities of two-dimensional materials, extensive research has been done on these structures. However, most described syntheses take lot time, are challenging, and ineffective. The present work demonstrates performance recently reported nanodiamond/graphene composite microsphere ND-GCSs as...
Two-dimensional (2D) nanomaterials are useful for building gas sensors owing to their desirable electronic and optical properties. However, they usually suffer from selectivity, because cannot discriminate between molecules. Functionalization with organic molecules can be used tailor surfaces recognize a specific family of compounds. In this study, solid-state density functional theory (DFT) was elucidate the functionalization MoS2 substituted aromatic diazonium salts (R = −H, – CH3, −CO2H,...
The inhibitive effect of 1-benzylpyridazin-1-ium bromide ionic liquid (MS20) on the corrosion carbon steel in molar HCl has been investigated by means weight loss measurements, kinetics and thermodynamics studies. A marked decrease rate (CR) was observed with increasing MS20 concentration. An effective inhibition ca. 91.3% efficiency (IE%) reached at 1 mM inhibitor temperature showed an reaching a peak value 97.5% 343 K. Results clearly revealed that activity proceeds via chemisorption...
Regulatory bodies play a crucial role in establishing limits for food additives to ensure quality and safety of products, as excessive usage poses risks consumers. In the context processed animal-based foodstuffs, nitrite is commonly utilized means slow down bacterial degradation. this study, we have successfully leveraged redox activity an electrochemically deposited polydopamine (pDA) film onto gold nanoparticle (AuNP)-modified screen-printed electrodes (SPCE) develop sensitive versatile...
