In this paper we present the results of a Fourier self-deconvolution and least-squares analysis of the MIR spectral data for KZn1−xCoxF3. An interpretation is given in terms of low-lying electronic transitions within the 4T1g(4F) ground manifold of Co2+ ions and their vibronics. We ...

课题组已在J.Am.Chem.Soc.上在线发表了题为“Photocatalytic CO2 conversion of M0.33WO3 directly from the air with high selectivity:insight into full spectrum induced reaction mechanism”的研究相关成果。文章的第一作者为武汉理工大学副教授吴晓勇和博士研究生李源,张高科教授为第一通讯作者,武汉理工大学赵焱...
DFT计算和in situ FT-IR结果表明,在光催化转化CO2反应中,M0.33WO3样品中的W5+位点在活化CO2分子的同时,也活化了水分子。光催化剂中的碱金属与W5+协同作用,增强了其宽谱光驱动的光催化转化CO2的活性。并通过介电函数计算和光催化条件实验的结果,探索了近红外光诱导的光催化还原CO2机理,结果证实近红外光诱导的小...
