Selective Electrochemical Reduction of Nitrogen to

The electrochemical nitrogen reduction reaction (NRR) provides a sustainable and alternative avenue to the Haber-Bosch process for ammonia (NHsub3/sub) synthesis. Despite the great efforts made on catalysts and electrolytes, unfortunately, current NRR suffers from low selectivity due to the overwhelming competition with the hydrogen evolution reaction (HER). Here, we present an adjusted

Functionalized layered double hydroxide applied to heavy

The use of functional material can help mitigate the pollution by heavy metals, which presents an array of risks to human production and life. This work provides a comprehensive review of the current knowledge on functionalized layered double hydroxide (LDH) as a heavy metal absorption material, by synthesizing the information from a total of 141 relevant publications published since 2005.

Ionic electroactive polymer metal composites:

After dehydrating the polymer samples, they are placed into a mixture of methanol (30–40% by weight)/ ionic liquid 72 and sonicated at 65 to 80 C. The diffusion of the ionic liquid into the Nafion membrane depends on the ionic liquid used, but is typically slow and therefore high temperatures (80 C) and long soaking times (4 h) are required.

PEH:Emulsion Treating

2017/4/26Ultrasonic tests can measure the wall thickness of vessels and piping to detect the existence and extent of corrosion. Mitigating or controlling corrosion of emulsion-treating equipment usually is accomplished by excluding oxygen, using corrosion inhibitors, applying internal coating, and/or using special metallurgy.

Polymer electrolyte membrane (PEM) fuel cells and electrolysers offer efficient use and production of hydrogen for emission-free transport and sustainable energy systems. Perfluorosulfonic acid (PFSA) membranes like Nafion and Aquivion are the state-of-the-art PEMs, but there is a need to increase the operating temperature to improve mass transport, avoid catalyst poisoning and electrode

What Are the Effects of Sulfuric Acid on Metal?

2021/2/18In practice, not all of these metals will react with sulfuric acid under normal circumstances. Although the pure metals will react, some elements, when exposed to air, quickly acquire a layer of oxide. The effects of this acid on metal oxides vary, but in some cases

Help with Alkene Synthesis

Explanation: Two sets of reagents are required to convert butanone into 2-butene. First, we use to reduce the butanone into a 2-butanol.Second, we use heat and acid to dehydrate the butanol and yield the final desired product. 1. ; 2. Heat/ may seem like an acceptable answer choice. may seem like

Frontiers

Achieving the goal of living in a sustainable and greener society, will need the chemical industry to move away from petroleum-based refineries to bio-refineries. This aim can be achieved by using biomass as the feedstock to produce platform chemicals. A platform chemical, 2,5-furandicarboxylic acid (FDCA) has gained much attention in recent years because of its chemical attributes as it can
