Electrochemical oxidation of lignin at IrO2-based oxide electrodes

Photocatalytic degradation of lignin on synthesized Ag–AgCl/ZnO nanorods under solar light and preliminary trials for methane fermentation

“…Most recently, some efforts have been done to find effective methods to degrade lignin for value-added biofuels and chemicals production, including enzymatic degradation (Chen et al, 2012) alkali pyrolysis (Guo et al, 2014), hydrothermal conversion (Barbier et al, 2012), electrochemical degradation (Tolba et al, 2010), biological degradation (Chang et al, 2014), photocatalytic degradation (Prado et al, 2013), etc. Among them, photocatalysis is considered as an environment friendly and promising technology due to excellent merits such as clean, effective, energy-saving, and low cost.…”

Effects of Oxide Composition on Structure, Surface Morphology, and Oxygen Evolution Behaviors of IrO₂-Ta₂O₅/Ti Anodes Prepared at a High Temperature

“…[38][39][40] Commercially available IrO 2 -Ta 2 O 5 coatings generally contain 70-80 mol% iridium and 30-20 mol% tantalum in combination with a titanium substrate, which are prepared by thermal decomposition of a precursor solution usually at a temperature of 450°C or more. The coatings obtained under such conditions are a mixture of crystalline IrO 2 and amorphous Ta 2 O 5 , which shows heterogeneous and mud-cracked surface and is known to have IrO 2 aggregates, flat areas, and cracks.…”

Novel Ti/Ta2O5-SnO2 electrodes for water electrolysis and electrocatalytic oxidation of organics

“…For example, they are efficient electrodes for sustaining the oxygen evolution reaction (OER), which is of great importance in water electrolyzers, rechargeable batteries, and zinc, copper, cobalt and nickel electrowinning processes. MMO electrodes have also been applied for electrochemical and, in particular, electrocatalytic oxidation of refractory organic compounds in wastewaters [9][10][11][12][13].…”
