This book was released on 2013-05-27 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Research for the development of more efficient photocatalysts has experienced an almost exponential growth since its popularization in early 1970’s. Despite the advantages of the widely used TiO2, the yield of the conversion of sun power into chemical energy that can be achieved with this material is limited prompting the research and development of a number of structural, morphological and chemical modifications of TiO2 , as well as a number of novel photocatalysts with very different composition. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a systematic account of the current understanding of the relationships between the physicochemical properties of the catalysts and photoactivity. The already long list of photocatalysts phases and their modifications is increasing day by day. By approaching this field from a material sciences angle, an integrated view allows readers to consider the diversity of photocatalysts globally and in connection with other technologies. Design of Advanced Photocatalytic Materials for Energy and Environmental Applications provides a valuable road-map, outlining the common principles lying behind the diversity of materials, but also delimiting the imprecise border between the contrasted results and the most speculative studies. This broad approach makes it ideal for specialist but also for engineers, researchers and students in related fields.

Book Synopsis Organic electronic materials for hydrogen peroxide production by : Maciej Gryszel
Download or read book Organic electronic materials for hydrogen peroxide production written by Maciej Gryszel and published by Linköping University Electronic Press. This book was released on 2020-02-25 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen peroxide (H2O2) is an important oxidant, used in various fields of industry, such as paper manufacturing, production of polymers, detergents, and cosmetics. Considering that the molecule degrades only to H2O and O2, it is regarded as a green chemical. Unfortunately, the incumbent method of H2O2 synthesis, based on anthraquinone oxidation, although efficient, is not environmentally friendly, as it requires fossil fuels and significant energy input. Therefore, there are efforts underway to reduce the ecological impact of hydrogen peroxide production. Some of the most promising approaches involve catalytic reduction of O2 to H2O2 in an aqueous environment. This can be coupled with water oxidation. As the required energy could be delivered in different ways, hydrogen peroxide synthesis can be achieved by electrocatalysis, photoelectrocatalysis, or photocatalysis. This thesis explores the possibility of using organic electronic materials as catalysts for H2O2 evolution in oxygenated water solutions. Organic electronics is a field of materials science focused on conducting and semiconducting organic molecules. These materials offer many possible advantages, related to low cost, flexibility, and good optoelectronic properties. Huge progress in the field over the last years led to their commercial applications in e.g. organic light emitting diodes and photovoltaics. Only very recently have organic electronics begun to be considered from the point of view of catalysis. In the first two papers, we investigate electrocatalytic activity of an organic pigment (PTCDI) and a conducting polymer (PEDOT) towards oxygen reduction to hydrogen peroxide. Both types of catalysts are chemically stable and able to operate in a wide pH range. In paper 3, we demonstrate that H2O2-evolving photocathodes can be based on an organic PN heterojunction, giving devices of a record-breaking performance. In the first part of paper 4, the same concept was tested for a naturally-occurring semiconductor, eumelanin, leading to a first report of photoelectrocatalytic properties of this material. In the second part of paper 4, as well as in papers 5 and 6, we explore, respectively, photochemical hydrogen peroxide synthesis with eumelanin, organic semiconductors, and organic dyes. We show that the photostability of catalysts is higher for materials with low-lying HOMO level and it can be increased by an addition of a reducing agent to the reaction system. Our findings prove that already existing organic electronic materials can be successfully applied in H2O2 evolution for environmentally friendly chemical synthesis, suggesting their use in harvesting of solar energy and in situ generation of hydrogen peroxide for biomedical applications. Väteperoxid (H2O2) är en viktig oxidant som används inom olika industrier, såsom papperstillverkning och produktion av polymerer, tvättmedel och kosmetika. Med tanke på att molekylen bryts ner till vatten (H2O) och syre (O2) betraktas den som en grön kemikalie. Tyvärr är den befintliga metoden för framställning av H2O2 baserad på oxidation av en antrakinon, en metod som är effektiv, men inte miljövänlig eftersom den kräver fossila bränslen och betydande energitillförsel. Det pågår därför ansträngningar för att minska den ekologiska effekten av väteperoxidproduktionen. Några av de mest lovande metoderna involverar katalytisk O2 till H2O2-reduktion i vattenlösning, kombinerat med vattenoxidation. Eftersom den nödvändiga energin kan levereras på olika sätt kan väteperoxidsyntesen uppnås genom elektrokatalys, fotoelektrokatalys eller fotokatalys. Denna avhandling undersöker möjligheten att använda organiska elektroniska material som katalysatorer för framställning av H2O2i syresatta vattenlösningar. Organisk elektronik är ett område inom materialvetenskap med fokus på ledande och halvledande organiska molekyler. Dessa material erbjuder många fördelar, såsom låg kostnad, flexibilitet och goda optoelektroniska egenskaper. Enorma framsteg på området har under de senaste åren lett till deras kommersiella tillämpningar i till exempel organiska ljusemitterande dioder och fotovoltaik. Nyligen har också organisk elektronik börjat övervägas ur katalysens synvinkel. I de två första artiklarna undersöker vi en elektrokatalytisk aktivitet av ett organiskt pigment (PTCDI) och en ledande polymer (PEDOT) i respekt till syrereduktion och väteperoxidproduktion. Båda typerna av katalysatorer är kemiskt stabila och kan arbeta inom ett brett pH-område. I artikel 3 visar vi att H2O2-producerande fotokatoder kan baseras på en organisk PN-gränsyta, vilket ger enheter med en rekordbrytande kapacitet. I den första delen av artikel 4 testades samma koncept för en naturligt förekommande halvledare, eumelanin, vilket ledde till en första rapport om fotoelektrokatalytiska egenskaper hos detta material. I den andra delen av artikel 4, samt i artikel 5 och 6, undersöker vi fotokemisk väteperoxidsyntes med eumelanin, organiska halvledare och organiska färgämnen. Vi visar att fotostabiliteten hos katalysatorer är högre för material med lågt liggande HOMO-nivå och att den kan ökas genom en tillsats av ett reduktionsmedel till reaktionssystemet. Våra fynd visar att redan befintliga organiska elektroniska material framgångsrikt kan tillämpas i H2O2-utvecklingen för miljövänlig kemisk syntes, vilket antyder att de kan användas för att ta tillvara på solenergi och för produktion av väteperoxid inom biomedicin.
