Understanding the Dynamics Governing Electrocatalytic Hydrodeoxygenation of Lignin Bio-Oil to Hydrocarbons.

Electrocatalytic hydrodeoxygenation (EHDO) is a promising approach for upgrading biomass-derived bio-oils to sustainable fuels without the use of high-pressure hydrogen gas and elevated temperatures. However, direct EHDO for realistic hydrophobic lignin-based oil production remains challenging. Herein, we discuss the molecular dynamics that govern the EHDO of lignin bio-oil over Pt/C in an acidic electrolyte added with 2-propanol or a surfactant.

Strategy for Enhancing Catalytic Active Site: Introduction of 1D material InSeI for Electrochemical CO Reduction to Formate.

The presence of oxygen vacancies (V) in electrocatalysts plays a significant role in improving the selectivity and activity of CO reduction reaction (CORR). In this study, 1D material with large surface area is utilized to enable uniform V formation on the catalyst. 1D structured indium selenoiodide (InSeI) is synthesized and used as an electrocatalyst for the conversion of CO to formate.

Electro-assisted methane oxidation to formic acid via in-situ cathodically generated HO under ambient conditions.

Direct partial oxidation of methane to liquid oxygenates has been regarded as a potential route to valorize methane. However, CH activation usually requires a high temperature and pressure, which lowers the feasibility of the reaction. Here, we propose an electro-assisted approach for the partial oxidation of methane, using in-situ cathodically generated reactive oxygen species, at ambient temperature and pressure.

Tailoring the Nanoporosity and Photoactivity of Metal-Organic Frameworks With Rigid Dye Modulators for Toluene Purification.

Facile synthesis of hierarchically porous metal-organic frameworks (MOFs) with adjustable porosity and high crystallinity attracts great attention yet remains challenging. Herein, a micromolar amount of dye-based modulator (Rhodamine B (RhB)) is employed to easily and controllably tailor the pore size of a Ti-based metal-organic framework (MIL-125-NH ). The RhB used in this method is easily removed by washing or photodegradation, avoiding secondary posttreatment.

Catalytic Oxidation of Methane to Oxygenated Products: Recent Advancements and Prospects for Electrocatalytic and Photocatalytic Conversion at Low Temperatures.

Methane is an important fossil fuel and widely available on the earth's crust. It is a greenhouse gas that has more severe warming effect than CO. Unfortunately, the emission of methane into the atmosphere has long been ignored and considered as a trivial matter.
