Photocatalysis can offer solutions for the transformation of greenhouse gases, such as methane and carbon dioxide. In the paper, a candidate for such a photocatalyst is presented, based on a composite of titania with carbon spheres. The material was obtained using microwave assisted solvothermal synthesis, enabling good dispersion of titania. The studies of carbon dioxide and methane adsorption were performed under ambient pressure and temperatures of 40, 60, and 80 °C. The effect of temperature increase was less favorable for carbon dioxide than for methane. Satisfying values of carbon dioxide and methane uptake were obtained-3.94 mmol CO/g and 2.77 mmol CH/g at 40 °C.
光催化可为甲烷和二氧化碳等温室气体的转化提供解决方案。在本文中，提出了一种基于二氧化钛与碳球复合材料的光催化剂候选材料。该材料采用微波辅助溶剂热合成法制备，可实现二氧化钛的良好分散。在环境压力和40、60和80°C的温度下进行了二氧化碳和甲烷吸附研究。温度升高对二氧化碳的影响比对甲烷的影响更不利。在40°C时获得了令人满意的二氧化碳和甲烷吸附量——分别为3.94 mmol CO/g和2.77 mmol CH/g。
