To solve those problems, solar energy is considered as a promising future energy and the conversion of CO2 into valuable materials is believed as an effective approach to control the emission of greenhouse gases. In recent years, we have made an effort to develop novel materials for dye-sensitized solar cells (DSSCs) and to convert CO2 into novel solid materials.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'> The dye-sensitized solar cell (DSSC) plays a leading role in the third generation photovoltaic devices. Currently, platinum is used as a standard counter electrode due to its excellent conductivity and catalytic activity. However, its practical application will be limited by its high cost and rare source. Therefore, it is necessary to develop efficient Pt-free counter electrodes for DSSCs. Very recently, we developed a novel strategy for the synthesis of shape-controlled 3D graphene sheets, which are based on our invented reaction of Li2O and CO to graphene. Furthermore, the synthesized 3D graphene sheets exhibited excellent performance as a counter electrode for DSSCs with a high energy conversion efficiency (7.8%) comparable to that of an expensive noble Pt electrode.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'> The conversion of CO2 represents a great challenge due to its high stability and low reactivity. However, we found that Li3N can rapidly react with CO2 into two important types of solid materials-carbon nitrides and lithium cyanamide. Different from current processes of CO2 conversion that are endothermic, this reaction is exothermic. Therefore, it constitutes not only a novel process for CO2 sequestration, but also a unique approach for synthesis of carbon nitrides and lithium cyanamide.<o:p></o:p></span></p><p class=MsoNormal><o:p> </o:p></p></div><div><div><div><p class=MsoNormal><b><span style='font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></b></p><p class=MsoNormal><b><span style='color:#1F497D'>Bio of Dr. Hu</span><span style='color:#002E7A'>: </span></b><o:p></o:p></p></div></div><div><div><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='color:#1F497D'>Dr. Yun Hang Hu is Charles and Carroll McArthur Endowed Chair Professor at Michigan Technological University.
