Feasibility of Waste Engine Oil Electrooxidation with Ni-Co and Cu-B Catalysts

2022

To implement a circular economy policy, methods of using waste products as a starting point for other technologies are constantly researched. One of the waste products that should be disposed of after use is waste engine oil (WEO). Despite the permanent introduction of the electrification of cars, the number of combustion vehicles (and, thus, the production of WEO) is constantly increasing. For these reasons, the reuse of WEOs is extremely important; e.g., to use these oils for energy purposes. One of the potential uses of this type of oil is as fuel for fuel cells (for direct electricity production). To lower the production costs of electrodes for fuel cells, catalysts that do not contain …

Methanol electrooxidation with Cu-B catalyst

2016

In the last few years alternative energy sources have been fast developing. One of these sources is fuel cell. Due to development of the renewable energy sources, the powering of fuel cells with bio-fuels is very important. The one of this fuel is methanol. The use of fuel cells on a large scale is mainly limited by the high cost of catalysts - mainly platinum. Elimination of Pt as catalyst would allow for wider commercial application of fuel cells. The paper presents a study of methanol electrooxidation on electrode with Cu-B alloy catalyst. Researches were done by the method of polarizing curves of electrooxidation of methanol in glass vessel. An aqueous solution of KOH was used as the el…

wytwarzania energii elektrycznej z substancji odpadowych, jak i technologii oczyszczania ścieków. Ogniwa te charakteryzują się niskimi kosztami inwestycyjnymi. Ze względu na znakomite własności katalityczne, w wysokowydajnych ogniwach paliwowych (np. wodorowo-tlenowych), jako katalizator stosowana jest platyna. Jednak koszt platyny praktycznie uniemożliwia stosowanie jej w MFC. Z tego względu należy poszukiwać innych katalizatorów nie zawierających metali szlachetnych. W mikrobiologicznych ogniwach paliwowych najczęściej stosuje się elektrody grafitowe. Praca przedstawia analizę możliwości wykorzystania stali nierdzewnej oraz stopu Cu-B jako katalizatora elektrody paliwowej w mikrobiologicz…
