was checked by the photocatalytic oxidation of methyl orange as a model compound under UV-vis light irradiation. The results show that, ALHTS catalysts acid leached by 20% sulphuric acid exhibit... recombination rate of the electron-hole pairs. The decoloration rate of methyl orange without adjusting pH reaches 87.3% under mercury lamp irradiation for 30 min. Key words: high titanium slag; hydro......

情况.然而,从图6(b)和(c)中可以发现,纯尿素所制备的g-C3N4光催化剂的具有最高的催化效率,2 h后,能达到96%的降解率,纯二氰二胺烧制出来的g-C3N4粉末催化效率只有约30%. 图6 不同g-C3N4粉末光催化降解甲基橙效果曲线 Fig. 6 Methyl orange degradation curves using different g-C3N4...的降解率变大,但是当催化剂到达一定浓度后,降解效率不再有明显提高.这可能是由于当催化剂浓度较高时,催化剂粉末的团聚以及光照深度的降低等原因导致降解效率的提升较慢. 图7 不同催化剂浓度情况下光催化降解甲基橙效率 Fig. 7 Photodegradation efficiency curves using catalyst of methyl orange......
, pectin, hemicellulose, and lignin, which are major constituents of orange peel, contain methyl esters that do not bind metal ions significantly. However, these methyl esters can be modified to carboxylate... Trans. Nonferrous Met. Soc.
