Electrochemistry with Micro- and Mesoporous Silicates

摘要: Publisher Summary This chapter presents an overview on the implication of microporous zeolites and ordered mesoporous silica-based materials in electrochemistry. There are numerous reasons why silicates attractive for electrochemical applications. Zeolites constitute a unique family displaying both ion exchange capacity size selectivity single component. would impart charge properties. The most commonly used connection to electrochemistry those characterized by rather high capacity, such as A, X, Y, L, mordenite, among some others. Silica-based materials, especially organic-inorganic hybrids, exhibit chemical physico-chemical features that might be readily exploited when modify electrode surfaces. responses ZMEs prepared with zeolite particles previously loaded redox species have been widely studied order understand located insulating environment likely undergo charge-transfer reactions how host affect their behavior. Most electron transfer involved associated mass transport so diffusion processes often limited sensitivity devices. Advanced applications electrodes modified (organo)silica were mostly developed field electroanalysis. Some other involving MPS reported, including gas sensors, potentiometry, electrochemiluminescence, photoelectrochemistry. films deposited surfaces sensitive adsorption, resulting measurable conductivity changes can detect gaseous analytes. Zeolite-polymer composite membranes well binder-free potentiometric sensing.
