Effect of doping TiO2 with Mn for electrocatalytic oxidation in acid and alkaline electrolytes

“…H 2 O 2 is a highly sought-after chemical due to its broad applications in industry, home, healthcare, and energy. [12][13][14] Unlike PEM electrolysis, the 2e À WOR does not rely on an acidic electrolyte. Rather, an alkaline electrolyte of potassium bicarbonate (KHCO 3 ) is commonly used.…”

Heat-fueled enzymatic cascade for selective oxyfunctionalization of hydrocarbons

“…Together with tuning carrier concentration, one might achieve an optimal alignment of the Fermi level and reaction potential. Furthermore, TEBC has a room for further engineering betterment of the system, such as surface engineering of catalyst 46 that can improve the H 2 O 2 generation capacity or a new reactor design 47 that can address the substrate/product loss issue and maximize the energy conversion efficiency. A methodology to generate a large temperature gradient to the reactor while consuming less power than that of current convection-based reactor would eventually increase the overall conversion efficiency of the TEBC.…”

Photoelectrochemical uranium extraction from uranium mine tailings seepage water

“…For the analysis of the feasibility of the proposed PEC U extraction method from the economic perspective, a cost-effective analysis is provided in Supplementary Note 11. We 50 . Hence, the net electrical power density of U is at least three and five orders of magnitude higher than the gross energy of H2 gas and concentrated H2O2, respectively.…”

“…On average, the net electrical energy density of U is estimated to be 43.3 MWh/kgU (Supplementary Note 13). In comparison, the gross energy densities of concentrated H2O2 (70% concentrated) and H2 gas, the state-of-art energy storage chemicals, were 0.58 kWh/kg and 33.35 kWh/kg, respectively 50 . Hence, the net electrical power density of U is at least three and five orders of magnitude higher than the gross energy of H2 gas and concentrated H2O2, respectively.…”

“…For long-term energy storage, converting and storing intermitting renewable electricity in the form of energy dense chemicals (e.g. H2 gas, H2O2) is of particular interest to the energy sector 50 . On average, the net electrical energy density of U is estimated to be 43.3 MWh/kgU (Supplementary Note 13).…”
