Thermal Effect on Photoelectrochemical Water Splitting Toward Highly Solar to Hydrogen Efficiency

“…Another study of thermal effects on BiVO 4 photoanode was conducted by BiVO 4 /CoO x photoanode. [120] The dynamic of hole transfer was analyzed by scanning photoelectrochemical microscopy (SPECM) and intensity modulated photocurrent spectroscopy (IMPS). SPECM is the powerful equipment for in situ analysis of fast and slow dynamics behavior using ultra microelectrode.…”

Superhydrophobicity-Enabled Efficient Electrocatalytic CO2 Reduction at a High Temperature

“…The rapid carbon dioxide (CO 2 ) emissions associated with increased fossil fuel consumption have led to global warming and the energy crisis. − Electrocatalytic reduction of CO 2 into fuels and chemical feedstocks is an important approach to address this global issue. − Electrocatalyst and reaction interface microenvironment optimization are commonly used strategies to promote the CO 2 reduction reaction (CO 2 RR) in efficiency and selectivity. − Increasing the reaction temperature is thought to promote the CO 2 RR because the kinetics of the elementary reaction is generally exponentially dependent on the temperature according to the Arrhenius law. − Unfortunately, as the temperature increases, the solubility of CO 2 decreases, and the reaction rate of the hydrogen evolution reaction (HER), a major competing reaction to the CO 2 RR, increases. , As a result, the CO 2 RR can be performed only at relatively low temperatures.…”

Fabrication of a Novel Co/CoO@Fe2V4O13 Composite Catalyst as a Photoanode for Enhanced Photoelectrochemical Water Oxidation

“…Electrochemical and photoelectrochemical water oxidation is a carbon‐free solution for producing energy. Photoelectrochemical (PEC) process, in which semiconductor photocatalysts converts solar power into chemical energy, has emerged as a promising, green, low‐cost, and carbon‐free solution in recent years [3–9] . This process produces hydrogen as a clean and carbon‐free energy source, unlike the conventional coal‐steam reforming reaction that accounts for 90 % of hydrogen production and causes a large carbon footprint and energy consumption [10,11] .…”
