In this study, titanium chips (TC) generated from industrial facilities was utilized as TiO2 support for hydrogenation of carbon dioxide (CO2) to methyl alcohol (CH3OH) over Cu-based catalysts. Nano-sized CuO and ZnO catalysts were deposited on TiO2 support using a co-precipitation (CP) method (CuO-ZnO/TiO2), where the thermal treatment of TC and the particle size of TiC2 are optimized on CO2 conversion under different reaction temperature and contact time. Direct hydrogenation of CO2 to CH3OH over CuO-ZnO/TiO2 catalysts was achieved and the maximum selectivity (22%) and yield (18.

- The greenhouse effect caused by carbon dioxide (CO2) is a critical global issue, prompting research into converting CO2 to methyl alcohol (CH3OH) using catalytic methods.
- A honeycomb-typed monolith was utilized as a catalyst support, which underwent both thermal and acid treatment to enhance its surface properties.
- Experiments indicated that while higher temperatures improved CO2 conversion in the hydrogenation process, they reduced selectivity for CH3OH, with optimal results achieved at around 250 degrees Celsius and 20 atm pressure.
