Hydrogen desorption catalysts titanium
WebHydrogen storage may be the bottle neck in hydrogen economy, where hydrogen spillover is in dispute as an effective mechanism. In this context, activated carbon (AC) was doped with nitrogen by using ammonia gas, and was further decorated with platinum, palladium, nickel, rhodium, iridium and ruthenium, via an ultrasound-assisted impregnation method, … Web24 nov. 2024 · Aerogels have interconnected networks and preeminent pore structures. When used as the catalysts for oxygen reduction reaction (ORR), they can facilitate the mass transfer and expose more active sites. Here, we synthesized the Fe-doped titanium oxide-based aerogels (TA/Fes) by the sol–gel method combined with thermal …

Titanium hydride has been widely studied for hydrogen storage, thermal storage, and battery electrodes applications. Web27 dec. 2024 · Titanium nanotubes were hydrothermally synthesized via a two-step method for ODS (oxidative desulfurization). The catalysts’ structures were characterized by XRD (X-ray diffraction), FT-IR, UV-Vis (UV-Vis diffuse reflectance spectra), NH 3 -TPD, etc. The effects of O/S molar ratio and catalyst dosage, etc., were systematically investigated.
WebMeanwhile, it can be seen that hydrogen adsorption and hydrogen desorption are two consecutive steps occurring in HER, and there is a clear competition between them. If the catalyst surface is weakly bound to hydrogen atoms, the HER process will be difficult; conversely, when the binding strength of hydrogen atoms on catalysts is too strong, the … Web10 apr. 2024 · The development of electrochemical systems is key toward the decarbonization of chemical industry.
