Re: Researchers invent novel catalyst to convert carbon dioxide

The first line says University of Amsterdam (UvA) have invented a new catalyst that can efficiently convert carbon dioxide (CO2) to carbon monoxide (CO). We are to assume that the equation yields a free Oxygen molecule...

Re: Researchers invent novel catalyst to convert carbon dioxide

Here is another Elemental boron is an effective photothermocatalyst for the conversion of carbon dioxide

A "self-heating" boron catalyst that makes particularly efficient use of sunlight to reduce carbon dioxide (CO2) serves as a light harvester, photothermal converter, hydrogen generator, and catalyst in one.

The researchers want to use this ordinary photothermic effect to increase the efficiency of catalytic systems. Their material of choice is powdered elemental boron, which very strongly absorbs sunlight and efficiently converts it photothermically, heating itself up remarkably. This allowed the team to carry out the efficient reduction of CO2 to form carbon monoxide (CO) and methane (CH4) under irradiation in the presence of water, with no additional reagents or co-catalysts.

Irradiation causes the boron particles to heat up to about 378 °C. At this temperature it reacts with water, forming hydrogen and boron oxides in situ. The boron oxides act as "traps" for CO2 molecules. The hydrogen is highly reactive and, in the presence of the light-activated boron catalyst, efficiently reduces the CO2 by providing the necessary protons (H+) and electrons.

Re: Researchers invent novel catalyst to convert carbon dioxide

OK.. it's a mazing how a few keystrokes can render different results.

With Low Temp plasma Techniques, we get two things we can work with
1. Dry Reforming of Methane Using Plasma-Catalysis
2. Methanation of CO2

Below 200 degrees (F), High Voltage Plasma, and a Nickel Coated Anode,
these things are possible, right now as we speak.

THIS would be yet ANOTHER excellent working experiment at the MDRS.
