The platform's versatility was demonstrated through the light-assisted hydrogenation of carbon dioxide, wherein this stable compound was transformed into gaseous reduction products, such as methane and carbon monoxide, through the application of heat and light. To comprehensively assess the impact of key variables such as light intensity, temperature, pressure, and flow rate, we conducted systematic experiments across a range of heterogeneous catalysts (See Supplementary Information for details). Among these catalysts, commercially available cobalt(II,III) oxide (Co3O4) was selected as a benchmark, providing a well-established reference for comparative analysis with other catalysts. Figure illustrates the selectivity, conversion, and productivity of the reaction under various operational conditions. Notably, the cobalt oxide catalyst exhibited remarkable selectivity towards methane production, with its formation increasing with rising reaction temperatures.
