  Bio-inspired synthesis of TiO2 hollow nanospheres in agarose gels

  摘要：

  TiO2 hollow nanospheres have been synthesized in agarose gels by a bio-inspired method for the first time in this study. Their outer and inner diameter are about 99.7 and 56.8 nm, respectively, and their shell has bimodal mesopores about 3.8 and 5.5 nm in size. These mesopores may be formed through removing the agarose gel fibers embedded in the shell of TiO2 hollow nanospheres during their nucleation and growth. It is inferred that a spherical composite formed by protamine and agarose molecules takes a key role in the formation of TiO2 hollow nanospheres. After calcined at high temperature (400-600 degrees C) for 2 h, these TiO2 materials exhibit higher photocatalytic activity for the methyl orange decoloration than Degussa P25 under artificial solar light irradiation. This study may provide a novel and facile approach for the synthesis of metal oxide hollow nanospheres under mild conditions. (c) 2013 Elsevier B.V. All rights reserved.

  A ternary V—Ti—P mixed oxide is shown to catalytically dehydrate 2-methyl-tetrahydrofuran in high conversion to give piperylene, in good yield. Volatile products collected from this reaction contain piperylene in concentrations as high as 80 percent by weight. Dehydration of glycerol to acrolein in high conversion and moderate selectivity is also demonstrated. The catalyst is also shown to dehydrate other alcohols and ether substrates. The catalyst is resistant to deactivation and maintains activity between runs.

  The invention relates to a catalyst composition comprising a mixed oxide of vanadium, titanium, and phosphorus modified with alkali metal. The titanium component is derived from a water-soluble, redox-active organo-titanium compound. The catalyst composition is highly effective at facilitating the vapor-phase condensation of formaldehyde with acetic acid to generate acrylic acid, particularly using an industrially relevant aqueous liquid feed.

  A series of Fe-Ti mixed oxide model catalysts containing different Ti/Fe ratios were synthesized and applied as catalysts for the High Temperature Fischer-Tropsch reaction (HTFTS). XRD, H2-TPR and in situ Mössbauer and XAFS spectroscopy were applied to evaluate the role of Ti on the physical and chemical properties of Fe within the mixed metal oxide. It was observed that the Ti/Fe ratio determines

  合成了一系列具有不同Ti / Fe比的Fe-Ti混合氧化物模型催化剂，并将其用作高温费-托反应（HTFTS）的催化剂。XRD，H 2 -TPR和原位Mössbauer光谱和XAFS光谱用于评估Ti对混合金属氧化物中Fe的物理和化学性质的作用。可以看出，Ti / Fe比决定了起始原料中赤铁矿，假板钛矿和锐钛矿的相对含量。这些相之间的相互作用决定了HTFTS的催化性能。 我们的结果表明假板钛矿的存在：i）增强铁的分散；ii）介导并控制活化过程中Fe（III）物种向碳化物转化过程中还原和渗碳程度，并且iii）通过最小化碳化铁的再氧化来增加HTFTS条件下的稳定性。Ti / Fe比为1 / 2.1的材料具有最高的催化活性和稳定性。

• Biomimetic synthesis of inorganic nanocomposites by a de novo designed peptide

  Inspired by the synthetic biology and biomineralization mechanism, a de novo designed biomimetic strategy is developed for the synthesis of metal oxide–metal nanocomposites (NCs) in aqueous solution under ambient conditions in this study. Via the screening of amino acids, it is found that arginine (R) can induce the formation of TiO2 and SiO2 nanoparticles (NPs), while tyrosine (Y) can reduce Ag+ and Au3+ ions into Ag and Au NPs, respectively. Subsequently, an artificial bifunctional peptide, arginine4tyrosine2 (R4Y2), as an example of this strategy, is designed to synthesize inorganic NCs including TiO2–Ag, TiO2–Au and SiO2–Ag, in which the positively charged moiety (R4) accelerates the polycondensation of negatively charged Ti or Si precursors, and the phenolic hydroxyl moiety (Y2) reduces Ag+ or Au3+ ions. This strategy may open an avenue for the green and controllable fabrication of a broad spectrum of inorganic NCs using artificial peptides as the inducer, designed rationally through encoding different parts of functional amino acids.

  受合成生物学和生物矿化机制的启发，本研究开发了一种全新的仿生策略，用于在环境条件下合成水溶液中的金属氧化物-金属纳米复合材料（NCs）。通过筛选氨基酸，发现精氨酸（R）可以诱导TiO2和SiO2纳米颗粒（NPs）的形成，而酪氨酸（Y）可以将Ag+和Au3+离子分别还原为Ag和Au NPs。随后，以人工双功能肽精氨酸4酪氨酸2（R4Y2）为例，设计了一种合成无机NCs的策略，包括TiO2-Ag、TiO2-Au和SiO2-Ag，其中带正电荷的部分（R4）加速了带负电荷的Ti或Si前体的缩聚，而酚羟基部分（Y2）还原了Ag+或Au3+离子。该策略为使用人工肽作为诱导剂，通过编码不同功能氨基酸的部分进行合理设计，从而绿色可控地制备各种无机NCs开辟了一条新途径。
