magnetic metals deposited on graphene hold the key to applications in spintronics. here, we present the results of Fe islands grown on graphene/Si C(0001) by molecular beam epitaxy, which are investigated by scanning tunneling microscopy. The two types of islands distinguished by flat or round tops are revealed, indicating bimodal growth of Fe. The atomic structures on the top surfaces of flat islands are also clearly resolved. Our results may improve the understanding of the mechanisms of metals deposited on graphene and pave the way for future spintronic applications of Fe/graphene systems.

近年来,在水处理领域中,利用高级氧化技术去除水中有机污染物引起了研究者的广泛关注.双氧水、过一硫酸盐(PMS)和过二硫酸盐(PDS)等氧化剂可以被含Fe,Mn,Cu和Co等过渡金属的催化剂活化,并通过产生的活性氧物质、高价金属或直接电子转移等途径实现污染物高效降解.其中,Co被认为是活化过硫酸盐最有效的物种之一.粉体ZIF-67和ZIF-9等Co基金属有机框架(Co-MOFs)在水体污染物去除方面得到了广泛关注,但面临稳定性差及回收困难等问题.经熔融-淬火工艺所制备的无定形MOF玻璃颗粒克服了粉体材料难以回收再利用的缺点,同时保持了其中催化位点的高活性.本文利用MOF玻璃作为非均相催化剂实现高级氧化降解水体微污染物,研究了其催化活化性能及反应机理.本文采用熔融-淬火方式将ZIF-62(Co)晶体转化成ZIF-62(Co)玻璃(ag-ZIF-62(Co)),并研究了ag-ZIF-62(Co)活化PMS降解磺胺甲恶唑(SMX)等微污染物的性能.粉末X射线衍射、傅里叶变换红外光谱、X射线光电子能谱(XPS)等表征结果表明,熔融-淬火过程使结构有序的ZIF-62(Co)晶体变成无定形的玻璃态ag-ZIF-62(Co),但并未破坏其中的有机配体和Co-N键.ag-ZIF-62(Co)可以在较宽的溶液pH范围(3.0-9.0)内高效催化活化PMS降解SMX等污染物.由于ag-ZIF-62(Co)玻璃活化PMS产生的SO_(4^(•-))自由基有可能被溶液中碳酸氢根消耗,所以溶液中的碳酸氢根浓度越高,SMX的降解效率越差.水中的氯离子会诱导产生HClO,从而提高ag-ZIF-62(Co)活化PMS降解SMX的效率.其他阴离子(如硝酸根、硫酸根与磷酸二氢根等)对ag-ZIF-62(Co)活化PMS降解SMX的效率无明显抑制或促进作用.利用自来水配制模拟含SMX废水,研究其中存在的多重阴离子和阳离子对ag-ZIF-62(Co)活化PMS降解SMX性能的影响.结果表明,ag-ZIF-62(Co)在30 min内对低浓度(1.0 mg/L)和高浓度(5.0 mg/L)SMX的降解效率均保持较高的水平.捕捉实验、电子自旋共振和自由基定量等实验证明了硫酸根自由基与单线态氧是降解SMX的主要活性物种.结合电喷雾质谱结果提出了SMX的降解路径,并评估了中间产物的毒性.利用XPS分析了ag-ZIF-62(Co)反应前后Co的价态变化,并结合其他实验结果阐明了硫酸根自由基与单线态氧的产生路径.为探究ag-ZIF-62(Co)在实际应用中的潜在价值,搭建了固定床反应器并填充ag-ZIF-62(Co).结果表明,ag-ZIF-62(Co)在反应器中能连续120 h活化PMS并高效降解SMX.此外,ag-ZIF-62(Co)还可以高效降解多种微污染物(如阿特拉津、双酚A、磷酸氯喹、氧氟沙星和罗丹明B等).ag-ZIF-62(Co)玻璃在水体系中活化PMS时,Co离子溶出低于GB 25467-20标准要求,有效地避免了Co离子带来的环境压力.综上所述,本文报道了ag-ZIF-62(Co)活化PMS降解水中SMX的性能,分析了不同因素对SMX降解效率的影响,并探究了活化PMS降解SMX的机理.通过搭建了固定床反应器,实现了对SMX的长时间高效降解,显示了ag-ZIF-62(Co)在AOPs中的应用潜力.本研究不仅为MOF玻璃在环境污染控制中的应用提供了新思路,也为后续MOF玻璃作为催化剂在环境催化领域的发展提供参考.

International Journal of Minerals,Metallurgy and materials 2018年第10期25卷 1132-1139页

作者： Shuang-hua zhang ya-jie zheng Pan Cao Chao-hui li Shen-zhi Lai xing-jun wang School of Metallurgy and Environment Central South University Western Region Gold Yili Co. Ltd

To provide a theoretical basis for a suitable process to extract gold from refractory gold concentrates, process mineralogy on the acid leaching residue of gold calcine was studied by chemical composition, X-ray diffraction, scanning electron microscopy-energy spectrum, and mineral dissociation analysis. The results showed that the acid leaching residue contained Au 68.22 g/t, Ag 92.71 g/t, Fe 0.44%, As 0.10%, and S 0.55%. Gold and silver minerals existed as native gold, argentite, and proustite. Quartz, the main gangue mineral, accounted for 78.33 wt/%. The dissociation degree analysis showed that the proportions of monomer and exposed gold in acid leaching residue were 96.66 wt%. The cyanidation results showed that the cyanide gold leaching rate of acid leaching residues was close to 100 wt%. However, the maximum cyanide gold leaching rate of gold calcine was only 85.31 wt%. This suggests that acid leaching can increase the gold dissolution rate in the cyanide process.

树干径向生长量(GROrate)和水分亏缺量(TWD)是树木响应环境因子的重要表征,分别受不同环境因子的影响,对环境因子的响应也不同。研究径向变化动态及其对环境因子的响应关系,对了解树木生长和生理特性应对气候变化具有重要意义。该研究利用高分辨率径向变化记录仪,连续记录2018-2020年红锥(Castanopsis hystrix)树干径向变化过程,同步监测环境因子,分析GROrate和TWD的动态变化及其与环境因子的关系。结果表明:径向生长的开始时间为3月4日至4月1日,结束时间为9月23日至11月5日,最大生长速率的出现时间为5月31日至6月8日。生长季内红锥生长呈不连续性,实际生长天数占整个生长季长度的47.8%-74.1%。生长季越长,生长发生的天数越多。日尺度上,在主要生长期(4-9月)环境因子中空气相对湿度(RH)、降水量(P)、光合有效辐射(PAR)和饱和水汽压差(VPD)与GROrate的相关性最强,而TWD的环境相关性与GROrate类似,但方向相反。21天滑动相关结果显示,在3年生长季的绝大部分时间VPD、P和RH是影响红锥径向变化的关键因素。月尺度上,GROrate与月降雨事件高度同步,而TWD与干旱期同步。因此红锥径向变化主要响应水分相关的环境因子,这将有助于更好地预测气候变化下森林动态的生长响应。
