<h2>Summary</h2><h3>Background</h3> Regular, detailed reporting on population health by underlying cause of death is fundamental for public decision making. Cause-specific estimates mortality and the subsequent effects life expectancy worldwide are valuable metrics to gauge progress in reducing rates. These particularly important following large-scale spikes, such as COVID-19 pandemic. When systematically analysed, rates allow comparisons consequences causes globally over time, providing a...
Photocatalytic water splitting is a sustainable technology for the production of clean fuel in terms hydrogen (H2). In present study, (H2) efficiency three promising photocatalysts (titania (TiO2-P25), graphitic carbon nitride (g-C3N4), and cadmium sulfide (CdS)) was evaluated detail using various sacrificial agents. The effect most commonly used agents recent years, such as methanol, ethanol, isopropanol, ethylene glycol, glycerol, lactic acid, glucose, sodium sulfide, sulfite,...
Solar conversion of carbon dioxide and water to value-added chemicals remains a challenge.
Solar-driven heterogeneous photocatalysis has been widely studied as a promising technique for degradation of organic pollutants in wastewater. Herein, we have developed sulfite-enhanced visible-light-driven photodegradation process using BiOBr/methyl orange (MO) the model photocatalyst/pollutant system. We found that rate MO was greatly enhanced by sulfite, and enhancement increased with concentration sulfite. The constant improved 29 times presence 20 mM Studies hole scavengers suggest...
Direct electrolysis of pH-neutral seawater to generate hydrogen is an attractive approach for storing renewable energy. However, due the anodic competition between chlorine evolution and oxygen reaction (OER), direct splitting suffers from a low current density limited operating stability. Exploration catalysts enabling OER overpotential below hypochlorite formation (≈490 mV) critical suppress chloride facilitate splitting. Here, proton-adsorption-promoting strategy increase rate reported,...
MXenes, a class of two-dimensional (2D) carbides and/or nitrides, are increasingly utilized in various electrochemical reduction reactions owing to their electronic conductivity, specific surface area, and tunable chemistry. Previous studies have indicated that the performance MXenes catalyzing hydrogen evolution reaction (HER) oxygen (ORR) is influenced by termination groups. However, our understanding how these groups affect electrocatalytic remains limited, especially for nitride MXenes....
A new class of treatment processes called advanced reduction (ARPs) is proposed. ARPs combine activation methods and reducing agents to form highly reactive radicals that degrade oxidized contaminants. Batch screening experiments were conducted identify effective by applying several combinations (ultraviolet light, ultrasound, electron beam, microwaves) (dithionite, sulfite, ferrous iron, sulfide) degradation four target contaminants (perchlorate, nitrate, perfluorooctanoic acid, 2,4...
In this work, effects of some experimental parameters (supporting electrolyte, initial pH, and current density) on aluminum corrosion anodic dissolution during electrocoagulation process were investigated. Potentiodynamic polarization tests, impedance spectroscopy measurements potentisotatic density transients used to evaluate verify supporting electrolyte pH corrosion. The presence NaCl Na2SO4 shifted the potential toward more cathodic potentials, indicating that is catalyzed by Na2SO4. On...
The immobilization of molecular switches within materials can give rise to new bulk properties that are useful for a variety applications.
With the synthesized Au/hydroxyapatite (HAp) nanocomposites, HAp nanorods favored adsorption of hydrazine, thus bringing hydrazine closer to catalytic sites Au nanoparticles and increasing efficiency oxidation.
Electrocatalytic water splitting using renewable electricity is widely recognized as a promising approach toward sustainable green hydrogen production. However, the energy efficiency of conventional electrolysis hindered by sluggish kinetics anodic oxygen evolution reaction. Several innovative strategies have been proposed to replace reaction, aiming lowering levelized cost hydrogen. One most notable emerging pursue alternative oxidation reactions. Here, we take critical look at an array The...
Sluggish kinetics of the anodic oxygen evolution reaction (OER) and minor upstream upsets in feed water quality remain bottlenecks for efficient electrolysis, which is exacerbated under near-neutral pH environments due to H2O dissociation. In this work, we report introduction a NiSx interlayer Co-(NiFe) oxide/nitride catalyst on nickel foam substrate. Postmortem OER characterization neutral synthetic seawater (SSW) shows that stable cationic [Co-(NiFe)]δ+ anionic [O-N]δ– surface species...
