Photoelectrocatalytic reduction of carbon dioxide to methanol at cuprous oxide foam cathode

Tailoring copper oxide semiconductor nanorod arrays for photoelectrochemical reduction of carbon dioxide to methanol.

Solar photoelectrochemical reduction of carbon dioxide to methanol in aqueous media was driven on hybrid CuO/Cu2O semiconductor nanorod arrays for the first time. A two-step synthesis was designed and demonstrated for the preparation of these hybrid copper oxide one-dimensional nanostructures on copper substrates. The first step consisted in the growth of CuO nanorods by thermal oxidation of a ...

Exergy and Energy Analysis of Effective Utilization of Carbon Dioxide in the Gas-to-Methanol Process

Two process models are used to convert carbon dioxide into methanol. These processes have been extended and improved using Aspen Plus simulator software. Both processes are found in the CO2 correction system. In this machine, the desired synthesis gas is produced in a flexible configuration. At the same time, the conversion of CO2 to hydrogen via a copper-based catalyst ha...

Discovery of a Ni-Ga catalyst for carbon dioxide reduction to methanol.

The use of methanol as a fuel and chemical feedstock could become very important in the development of a more sustainable society if methanol could be efficiently obtained from the direct reduction of CO2 using solar-generated hydrogen. If hydrogen production is to be decentralized, small-scale CO2 reduction devices are required that operate at low pressures. Here, we report the discovery of a ...

Photocatalytic Reduction of Carbon Dioxide to Formic Acid, Formaldehyde, and Methanol Using Dye-Sensitized TiO2 Film

A bifunctionalized TiO2 film containing a dye-sensitized zone and a catalysis zone is designed for visible-light photocatalytic reduction of CO2 to chemicals continuously. Charge separation can be accomplished with electron transferring to catalysis zone and positive charge transforming to anode. Highly efficient conversion of CO2 to formic acid, formaldehyde, and methanol is achieved through t...
