Amolten salt process was developed to prepare CoP nanoparticles(NPs) embedded, N,P co-doped carbons with the combination of hand milling and high temperature carbonization. The characterization results implied that the as-prepared samples possessed mesoporous structures. Moreover, the mass ratios of the precursors affected the crystalline structures and the porosities of the final electrocatalysts. The as-prepared catalysts exhibited excellent electrocatalytic performances towards hydrogen evolution reaction(HER) under acidic and alkaline conditions. The as-prepared samples were designed as GxMyCoz, where x, y and z meant the amounts of glucose, melamine and CoCl2, respectively. The optimum sample of G6.0M2.0Co5.0 showed the best HER property with a low onset overpotential and a small Tafel slope, as well as excellent electrocatalytic stability.

过渡金属掺杂TiO_(2)目前仍被认为是最有前途的光催化材料之一,可以用于解决环境问题(如废水处理),但在解释金属离子对TiO_(2)基体作用机理上仍具有挑战性。评估了高分散Fe掺杂TiO_(2)催化剂的光催化活性并探究了其对TiO_(2)基在能带结构上的作用机理,通过超声浸渍法配合高温烧结法制备低质量分数(0.33wt.%)掺杂的FeOx/TiO_(2)复合催化剂,借助XRD,TEM,UV-Vis,PL和FLT对复合催化剂进行了表征分析。用罗丹明B(RhB)和亚甲基蓝(MB)模拟废水,在300 W汞灯(λ=365 nm)条件下对催化剂的性能进行评估。结果表明,MB可在15 min内达到完全降解,较纯TiO_(2)缩短了66%。该催化剂实现了原子级的Fe掺杂,促进电荷的分离从而提高了光催化活性。研究结果为环境污水治理问题提供了具体的解决方案,为过渡金属掺杂半导体光催化材料的设计提供了新思路。

本文首先以蔗糖为前驱体水热法合成碳微球,通过调整水热时间(6~24 h)改变碳微球粒径和表面性能,然后再以其为模板制备了LaFeO_3钙钛矿.X射线粉末衍射(XRD)、透射电子显微镜(TEM)、X射线光电子能谱(XPS)、N_2物理吸附等表征结果表明,样品均为钙钛矿结构,且晶系结构随碳微球水热时间的增加由斜方晶系向立方晶系转变;与无模板条件下制备的LaFeO_3相比,碳微球模板制备的LaFeO_3具有更好的比表面积、分散度和表面化学性能.室温下测试了LaFeO_3催化分解H_2O_2性能,以及H_2O_2氧化消除罗丹明B的性能.结果表明,LaFeO_3具有较好的催化H_2O_2氧化罗丹明B性能,其中以碳微球水热时间20 h为模板制备的LaFeO_3(标记为LaFeO_3-C20)表现出最高的活性;通过比较H_2O_2分解和氧化罗丹明B的活性变化可知,H_2O_2催化分解的中间产物是氧化罗丹明B的活性物种.最后,对LaFeO_3-C20样品进行了6次催化氧化罗丹明B的循环实验,发现催化剂在6次循环后无活性下降,说明LaFeO_3-C20在反应中有非常好的稳定性.
