Currently, conventional dimethoxymethane synthesis methods are environmentally unfriendly. Here, we report a photo-redox catalysis system to generate dimethoxymethane using a silver and tungsten co-modified blue titanium dioxide catalyst (Ag.W-BTO) by coupling CO reduction and CHOH oxidation under mild conditions.

A high valent Fe(VI) homogenous catalyst was synthesized following electrochemical route for the efficient removal of a greenhouse gas (NO) by mediated electro catalytic oxidation (MEO) in an electro-scrubbing process. This paper describes the room temperature degradation of NO using a consistently generable hexavalent Fe(VI) homogenous catalyst. The ferrate (VI) was electrochemically generated by employing a membrane divided cell, and quantified by monitoring the changes in the ORP (oxidation/reduction potential) along with a potentiometric titration by the chromite method using chromium Cr(III) as a titrant.

Because of the abundance of transition metals, their enhanced electrochemical/chemical efficiency on par with the benchmark catalysts, long-term stability, etc., the expansion of transition metal/metal oxide-based electrocatalysts for oxygen evolution, urea oxidation reactions and 4-nitrophenol reduction becomes indispensable. In particular, the abundant availability along with improved electrochemical performance is crucial for fuel cell applications when it comes to large scale commercialization.

Online monitoring of gas pollutants in the gas phase at room temperature using an electrochemical macro gas flow sensor is challenging and important for the pollutant treatment process. In this work, for the first time, we tried to explore the homogeneous and heterogeneous application of Ni(II) (CN) in the KOH environment for the removal and monitoring of toxic nitric oxide gas. The homogeneous electrogenerated Ni(I) (CN) was effectively removing the toxic nitric oxide gas by electro scrubbing method and the novel Ni(II) (CN) and KOH modified electrode used for heterogeneous sensor application with high sensitivity, and reliability toward Nitric oxide gas.
