Abstract: The present invention is generally directed to the production of low-carbon syngas from captured CO2 and renewable H2. The H2 is generated from water using an electrolyzer powered by renewable electricity, or from any other method of low-carbon H2 production. The improved catalysts use low-cost metals, they can be produced economically in commercial quantities, and they are chemically and physically stable up to 2,100° F. CO2 conversion is between 80% and 100% with CO selectivity of greater than 99%. The catalysts don't sinter or form coke when converting H2:CO2 mixtures to syngas in the operating ranges of 1,300-1,800° F., pressures of 75-450 psi, and space velocities of 2,000-100,000 hr−1. The catalysts are stable, exhibiting between 0 and 1% CO2 conversion decline per 1,000 hrs. The syngas can be used for the synthesis of low-carbon fuels and chemicals, or for the production of purified H2. The H2 can be used at the production site for the synthesis of low-carbon chemical products or compressed for transportation use.

Abstract: The present disclosure provides a synthesis method of a g-C3N4/C composite material based on a hollyhock stalk, including the following steps: (1) pretreatment of hollyhock stalks; and (2) fabrication of the g-C3N4/C composite material. In this method, with the hollyhock stalk as a carbon skeleton, g-C3N4 is spread on a template surface to form a laminated layer, and a composite system with a special structure is constructed. Compared with pure phase g-C3N4, the composite material substantially increases specific surface area and has a clear interface; the carbon skeleton not only functions as a rigid support, but also increases the electron transfer efficiency of the composite material, thereby improving the separation efficiency of photogenerated carriers and the utilization rate of visible light. Raw materials used in the method are inexpensive and environmentally friendly, which can be used for industrial production and bulk production of eco-friendly materials for harnessing environmental organic pollutants.
