A new molecular catalyst based on cobalt complex [LCoCl] (1) is formed by the reaction of N, N-dimethylethylenediamino-N,N-bis(2,4-dimethyl) phenol (H2L) with CoCl2 6H2O for electrolytic water reduction. To our knowledge 1 is by far the most active electrocatalyst for hydrogen generation from water with a turnover frequency (TOF) of 2744 mol of hydrogen per mole of catalyst per hour at an overp...

In this work an integrated facility is proposed that produces methanol from switchgrass and uses the captured CO2 to enhance the production capacity by 50% via CO2 hydrogenation. The process consists of two sections, biomass processing to syngas and its conversion to methanol, and the electrolytic section where hydrogen is produced to hydrogenate the CO2 that has been captured during syngas cle...

The behaviors of reduction of NpO2 by controlled potential electrolysis were studied, and a unique time course of electrolysis current was observed. It was concluded that NpO2 was reduced by two reduction processes, which were the chemical reaction with Np and the electrocatalytic reduction by adsorbed hydrogen atom on platinum electrode surface. The time courses of current for controlled poten...

Alkaline electrolyzers are the most widespread technology due to their maturity, low cost, and large capacity in generating hydrogen. However, compared proton exchange membrane (PEM) electrolyzers, they request use of potassium hydroxide (KOH) or sodium (NaOH) since electrolyte relies on a liquid solution. For this reason, performances alkaline governed by concentration operating temperature. D...

The comprises several equations such as equation, momentum energy transport equation. comp...

Electrolytic water splitting, as a promising route to hydrogen (H2) production, is still confronted with the sluggish anodic oxygen evolution reaction (OER) and its less value-added O2 production. Herein, we report bifunctional electrode fabricated by in situ growth of Mn-doped CoSe2 nanonetworks on carbon fiber cloth (Mn-CoSe2/CFC), which shows attractive electrocatalytic properties toward gly...

Hydrogen is considered to be the most promising candidate as a future energy carrier. One of the most used technologies for the electrolytic hydrogen production is alkaline water electrolysis. However, due to the high energy requirements, the cost of hydrogen produced in such a way is high. In continuous search to improve this process using advanced electrocatalytic materials for the hydrogen e...

Various basic, efficient and cheap techniques are used for the purpose of life forecast and failure detection of aluminum electrolytic capacitors which are utilized as a part of many power electronic converters. The main idea of these techniques is to calculate the values of Equivalent Series Resistance (ESR) and Capacitance (C). Observing the ESR values, valuation of changes in voltage and cur...
