Oxygen evolution on well-characterized mass-selected Ru and RuO2nanoparticles

“…Of the different water splitting technologies, proton exchange membrane (PEM) electrolysers are arguably the most amenable towards small-scale delocalized storage of renewable electricity. 4 Whereas traditional electrolysers operate in base, proton exchange membrane (PEM) electrolysers operate in acid. They hold some distinct advantages over traditional alkaline electrolysers, namely: 14 (a) high efficiency at high current density, (b) the ability to manage fluctuating power inputs, (c) a solid electrolyte, and (d) a fast start up time.…”

Highly active and durable non-precious-metal catalysts encapsulated in carbon nanotubes for hydrogen evolution reaction

“…[5][6][7][8][9][10] However, 3d TMs are not stable in acids and therefore exclude their application in an acidic solid polymer electrolyte (SPE), which is considered to be more efficient and exquisite for HER compared with the alkaline electrolyser. 11 In recent years, molybdenum-based materials, such as MoS 2 , [12][13][14][15][16][17][18][19] MoSe 2 , 14,20 Mo 2 C, 21,22 MoB, 22 MoS 2 analogues, 23 NiMoN x , 24 and Co 0.6 Mo 1.4 N 2 , 25 have evolved as possible alternatives for HER in acidic electrolytes, while the durability of Mobased catalysts is still not satisfactory when they suffer strongly acidic electrolytes under the long-time operation or accelerated degradation measurements.…”

Recent progress on electrochemical production of hydrogen peroxide

“…Electrochemical devices [56] and electrolysis of water [60] operated at ambient temperature and pressure [90] in small plants can be helpful in storage, electrochemical energy conversion process, and in transformation, as they require minimal capital investment. In electrochemical production of H 2 O 2 catalyst at the electrodes is of crucial importance so presently, the main challenge in focus is to find a material that can efficiently and selectively produce H 2 O 2 .…”

“…Electrochemical devices can be helpful in playing a major role in the transformation, as they require minimal capital investment and can be operated at ambient pressures and temperature in small plants. [56] Herein, production of hydrogen peroxide from reduction of oxygen is focused, a chemical with particularly increased electrochemical production. [16] Direct process of H 2 O 2 synthesis does not make use of embedded energy released upon reacting H 2 and potentially explosive mixtures of oxygen and hydrogen are need to be handled during the process.…”
