Considering the ever-increasing world demand for energy and the negative consequences of climate change, it is necessary to pay more attention to the development of renewable energy resources. Recently, a lot of emphasis has been placed on renewable ways of obtaining electricity such as solar, wind, and thermal, however, taking into account their volatility, there is a need for intermittent energy storage. Nowadays most commonly used intermitted storage medium is lithium-ion batteries, however, due to the high cost and scarcity of lithium it’s not suitable for large-scale applications. One way is to use hydrogen as a storage medium. For now, only 4% of wolds hydrogen is produced using electrolysis. Decoupled electrolysis has major benefits in comparison with traditional electrolysis methods which increases the need for low-cost high-capacity electrode materialsSurfactant has a significant role in TiO2 capacity in acidic conditions. TiO2 capacity increases by 50 % without surfactant and is 166.68 F/g compared to 118.03 F/g. In alkaline conditions, differences can’t be observed. In comparison with P25 pure TiO2 capacity is increased by 2.4 times in acidic conditions. Major factors for this difference are particle size and a rutile crystal phase with a lower gravimetric capacity. Cycle times haven’t significantly changed even after 500 cycles.
