Synthesis of Inorganic Phosphorus Compounds and Their Changes in Structure and Surface Property by Grinding

几种非有机磷酸盐化合物是由研究引起的结构、催化活动和人性敏感性引起的变化。当crystalline AIPO_4有机磷化合物在催化活性和物理化学性质中的变化在有机溶剂和水的混合物中合成，它对顺式-2-丁离子异构化的催化活性已经退化，它的特定表面区域、波体积，也意味着波辐射也已经退化。同样，在克里斯汀YPO_4的情况下，其1-butene异构化的催化活动被消除，其特定的表面区域和Porno体积被减少，也意味着Porno半径被消除。当水晶钛（HPO_4） _2·nH_2O和TiP_2O_7在地面上改变了表面酸度，并且由于特定表面区域的1-butene异构化而变得更好。在被研磨的磷酸盐活动中的增加 ... More 这是一种假定，要暴露出一种不对称物质在它们的体积中，以及模拟物质在计算后对活性物种的转变。BPO_4对顺式-2-butene或propene的分子化的活动已被研磨所增加。特定的表面区域也同样增加，而Porno体积和平均Porno半径减少。该活动主要归因于青铜酸网站的存在，而其他因素如Porn体积和平均Porn Radius应该受到考虑。对钛（HPO_4）_2·nH_2O和Cu-P-Y复合氧化物对其人性感应特性的影响：钛（HPO_4）的固酸度2·nH_2O与其电传导密切相关，当它被放置在湿大气层中。“它的电抵抗力对人类的依赖允许它作为人类传感器而被利用。”在制造过程中。Ti （HPO_4） _2·nH_2O is subjected to grinding and heating。通过这样的治疗，其酸性物质将发生变化，并且作为一个结果，人性化感知的性格也将发生变化。因此，从Ti （HPO_4） _2准备的湿度传感器·nH_2O与从非地面Ti （HPO_4） _2准备的湿度传感器相比，它们之间没有明显的差异。类似的结果被用于Cu-P-Y复合氧化物传感器。Less（低）

Several inorganic phosphorus compounds were synthesized and their changes in structure, catalytic activity, and humidity-sensitivity by grinding were investigated.1. Synthesis of several inorganic phosphorus compounds and their changes in catalytic activity and physicochemical propertyWhen crystalline AIPO_4 which were synthesized in a mixture of organic solvent and water was ground, its catalytic activity for cis-2-butene isomerization was decreased, and its specific surface area, pore volume, and mean pore radius were decreased too. In the case of crystalline YPO_4 also, its catalytic activity for 1-butene isomerization was decreased, and its specific surface area and pore volume were decreased, although mean pore radius was increased. When crystalline Ti (HPO_4) _2・nH_2O and TiP_2O_7 were ground, their surface acidity was changed, and the activity for 1-butene isomerization as well as the specific surface area were increased. The increase in activity of those phosphates by grinding … More was considered to be due to the exposure of an amorphous material involved in the bulk of them, and the transformation of the amorphous material to active species after calcination. The activity of BPO_4 for the oligomerization of cis-2-butene or propene was increased by grinding. The specific surface area was also increased, while the pore volume and mean pore radius were decreased. The activity was mainly ascribed to the presence of Bronsted acid sites, although the other factors such as pore volume and mean pore radius should be considered.2. Effect of grinding of Ti (HPO_4)_2・nH_2O and Cu-P-Y composite oxides on their humidity-sensing characteristics The solid acidity of Ti (HPO_4) _2・nH_2O is closely related to its electric conductivity when it is placed in a wet atmosphere. The dependence of its electric resistance on humidity allows it to be utilized as a humidity sensor. In the manufacturing process. Ti (HPO_4) _2・nH_2O is subjected to grinding and heating. By such treatments, its acidic property will be changed and as a result the humidity-sensing characteristic will also be changed. Therefore, the humidity sensor prepared from Ti (HPO_4) _2・nH_2O which was ground before being pressed and heated was compared with that prepared from non-ground Ti (HPO_4) _2・nH_2O.However, contrary to expectation, there is no significant difference between them. Similar result was obtained for Cu-P-Y composite oxide sensor. Less
