Ti\u1ec3u s\u1eed:<\/h2>\n
In recent years, the annual increase in global CO2 emissions has been a serious threat to the ecological environment in which people live. (There has been 410 ppm in 2018 \u2013 data from the National Oceanic and Atmospheric Administration’s Hawaiian Islands Mauna Loa Volcano’s greenhouse gas monitoring station). Therefore, the capture, storage and conversion of CO2 has received wide attention from researchers. Toyota Central Research has used water and carbon dioxide as raw materials to synthesize useful substances using sunlight, and the energy conversion efficiency has increased to the highest 4.6% in the world. BASF in Germany converts carbon dioxide into a carbonate polymer material with a wide range of applications. Bayer can use carbon dioxide in flue gas from thermal power plants as the main raw material for the production of polyurethane materials. There is a stable catalyst market for the production of carbonates, but the utilization of CO2 is still far from enough. The conversion of hydrocarbon fuels is still in the basic research stage of application. China’s 13th Five-Year Plan and the Sino-US Joint Statement on Climate Change have made \u201ccarbon reduction\u201d a construction goal, encouraging the conversion of CO2 based fuels. And include it in the “13th Five-Year” National Basic Research Special Plan (Guo Ke Fa Ji [2017] No. 162). The use of solar energy to convert low-cost and abundant CO2 and water into a hydrocarbon fuel with convenient storage, mature technology, wide application fields and huge demand is a green solar chemical conversion technology.<\/div>\n

Product Evaluation: Evaluation of the catalytic product is the last and most important part of the overall system. The products taken are generally classified into offline (commonly known as “needle type”) and online detection (online). Depending on the nature of the catalytic product, the detection equipment generally has gas chromatography, mass spectrometry, and liquid chromatography.
