修饰在磁棒状羟基磷灰石/MIL-101(Fe) 纳米复合材料上的 Ag NPs 作为还原某些硝基芳烃化合物的有效催化剂和有效的抗菌剂
摘要:
在这项工作中,通过将 Ag 和 Fe 3 O 4纳米粒子加载到羟基磷灰石/MIL-101(Fe) 金属有机骨架的表面上,成功合成了棒状磁性纳米复合材料。使用各种技术研究了 HAP/MIL-101(Fe)/Ag/Fe 3 O 4的结晶性质、尺寸、形态以及磁性和结构特性纳米复合材料,包括 X 射线衍射 (XRD)、傅里叶变换红外 (FT-IR) 光谱、拉曼光谱、场发射扫描电子显微镜 (FE-SEM)、能量色散 X 射线光谱 (EDX)、透射电子显微镜(TEM)、振动样品磁强计 (VSM)、BET 表面积测量和 zeta 电位分析。结果表明,纳米复合材料样品由附着在棒状羟基磷灰石/MIL-101(Fe) 上的Ag 和 Fe 3 O 4纳米颗粒组成。所制备的HAP/MIL-101(Fe)/Ag/Fe 3 O 4的催化和抗菌性能被研究。这种纳米复合材料被用作催化还原有毒污染物的多相催化剂,包括 4-硝基苯酚

A hair coloring composition comprising: (a) from about 0.0003 moles (per 100 g of composition) to less than about 0.09 moles (per 100 g of composition) of an inorganic peroxygen oxidizing agent; and (b) an oxidative hair coloring agent; wherein the pH of each of (a) and (b) is in the range of from about 1 to about 6 and wherein the combined mixture of (a) and (b) has a pH in the range of from about 1 to about 6. The products can provide excellent hair coloring and in-use efficacy benefits including excellent initial color and good wash fastness in combination with reduced hair damage at low pH.
A hair colouring and conditioning composition comprising:
(a) a hair colouring agent; and
(b) a hair conditioning agent;
wherein the composition provides an Average Combing Index Value of greater than 1.2 as measured by the Combing Technical Test Method.
The products can provide excellent hair colouring together with excellent conditioning, reduced hair damage, brittleness and dryness, and is convenient and easy to use.

Aromatic azole compounds such as 2-(4-aminophenyl)-5-amino-benzimidazole are prepared in an organic sulfonic acid solvent instead of polyphosphoric acid. This allows recovery and recycle of the solvent and avoids the handling and environmental concerns resulting from the use of polyphosphoric acid. The resulting compounds find use in the pharmaceutical industry, as anticorrosion agents, and as precursors for high-performance fibers having high strength, stiffness, and flame resistance.

Compositions for dyeing keratin fibers comprise (a) at least one keratin dyeing compound selected from aromatic systems which comprise at least one boronic acid or boronic ester moiety and which are capable of forming upon oxidation a nucleophile or an electrophile, (b) at least one additional keratin dyeing compound selected from the group consisting of auxiliary developers and auxiliary couplers, and (c) a cosmetically suitable medium. Methods for oxidatively dyeing keratin fibers comprise the steps of applying such compositions in the presence of an oxidizing agent and rinsing the hair. A hair coloring product in kit form comprises a first separately packaged container comprising a composition as described above and a second separately packaged container comprising an oxidizing agent.
